The new Synergistic Research BLUE fuses ....
I’ve replaced all 5 of the SR BLACK fuses in my system with the new SR BLUE fuses. Cold, out of the box, the BLUE fuses stomped the fully broken-in SR BLACKS in a big way. As good as the SR BLACK fuses were/are, especially in comparison with the SR RED fuses, SR has found another break-through in fuses.
1. Musicality ... The system is totally seamless at this point. Its as if there is no system in the room, only a wall to wall, front to back and floor to ceiling music presentation with true to life tonality from the various instruments.
2. Extension ... I’ve seemed to gain about an octave in low bass response. This has the effect of putting more meat on the bones of the instruments. Highs are very extended, breathing new life into my magic percussion recordings. Vibes, chimes, bells, and triangles positioned in the rear of the orchestra all have improved. I’ve experienced no roll-off of the highs what so ever with the new BLUE fuses. Just a more relaxed natural presentation.
3. Dynamics ... This is a huge improvement over the BLACK fuses. Piano and vibes fans ... this is fantastic.
I have a Japanese audiophile CD of Flamenco music ... the foot stomps on the stage, the hand clapping and the castanets are present like never before. Want to hear natural sounding castanets? Get the BLUE fuses.
4. Mid range ... Ha! Put on your favorite Ben Webster album ... and a pair of adult diapers. Play Chris Connor singing "All About Ronnie," its to die for.
Quick .... someone here HAS to buy this double album. Its a bargain at this price. Audiophile sound, excellent performance by the one and only Chris Connor. Yes, its mono ... but so what? Its so good you won’t miss the stereo effects. If you’re the lucky person who scores this album, please post your results here.

Overall impressions:
Where the RED fuses took about 20 hours to sound their best, and the BLACK fuses took upwards of 200 hours of total break-in, the BLUE fuses sounded really good right out of the box ... and that’s without doing anything about proper directional positioning. Not that the BLUE fuses don’t need breaking in, they do. The improvement continues through week three. Its a gradual break-in thing where each listening session is better than the last.
Everything I described above continues to break new ground in my system as the fuses continue breaking in. Quite honestly, I find it difficult to tear myself away from the system in order to get things done. Its truly been transformed into a magical music machine. With the expenditure of $150.00 and a 30 day return policy there’s really nothing to lose. In my system, its like upgrading to a better pre amp, amp, CD player or phono stage. Highly recommended.
Kudos to Ted Denney and the entire staff at SR. Amazing stuff, guys. :-)

PS: If you try the SR BLUE fuses, please post your results here. Seems the naysayers, the Debbie Downers and Negative Nellie’s have hijacked the original RED fuse thread. A pox on their houses and their Pioneer receivers.

There is a free on-line test for high frequency hearing.
http://www.noiseaddicts.com/2009/03/can-you-hear-this-hearing-test/ This test requires the speakers being capable of reproducing high frequencies. My Audio Engine speakers do that (my wife's computer's generic speakers for $20 stop between 12 and 15Khz). My hearing test resulted in a max frequency of 17Khz. When I was a child with asthma, I could hear between 20 and 30Khz. Children with bronchial diseases for some reason can hear high frequencies and transformer humming can be an annoyance. |
It is nice that designer Ted Denney with Synergistic Research Inc. is participating on this thread. I have found it insightful when designers/manufacturers show up here to discuss and help us understand their products. Unfortunately, Ted's posts here have largely reiterated SR's marketing rhetoric about how they believe their fuses sound, but have not answered the technology-based questions that have been asked here about how any fuse, and specifically their fuses, can affect the tone and sound of a system to the degree indicated by both their marketing advertisements and by many of their fuse users. I am also curious about how they are moving the technology forward to the point where each of four iterations of fuses can have such a reportedly "profound" improvement over the previous iteration. Thanks for any insights. |
As someone who likes to know how things work, I would be delighted to read anything Mr. Denney wishes to share. Having said that, I can think of a number of perfectly valid reasons why he might choose not to. The obvious fact that the skeptics and detractors try to gloss over for their own purposes is that the performance of SR products is completely independent of his willingness, or unwillingness, to explain how they work. |
Why would any manufacturer reveal how his/her products work? In a totally competitive market like audio there are those waiting on the side lines to steal someone else’s technology and profit from it. Ted Denney owes these yahoos nothing. His road to success is to continue producing innovative products that are perceived to perform beyond the price paid by the end consumer. As a result, the man is experiencing a ton of success, and deservedly so. Here’s the key: "Help as many people get what they want FIRST, and you will get what you want in return." tommylion ... You’re getting fantastic cello and double bass sound now, right? Amazing, no?? The combination of the tube dampeners and the Blue fuses are killer. But ... just wait until the "secret tweak" comes on the market. Like the old vaudeville crooner used to say ... "You ain’t heard nuttin’ yet. :-) And speaking of music, does it get any better than this: https://www.youtube.com/watch?v=3UTmuKLoEeQ https://www.youtube.com/watch?v=upJ3OgMRiUA And she lives on ... https://www.youtube.com/watch?v=ZSfgCIGd7k4 Frank |
Since there seems to be some confusion regarding the question I’ve left on the table, I’ll point out that I for one have never asked for "trade secrets" or any proprietary stuff from Uncle Ted…simply some general description of why this fuse does what is claimed. For some this "ruins" the thread since apparently inexplicable faith in mysterious things is somewhat tenuous to the insecure. I get it. Regarding my "if it sounds good, it’s good" post (context…that's an actual thing), there’s "good" and there’s what I see as preposterous faith based claims of sonic transformation to systems far beyond what could be caused by a fuse, and, of course, my test of the black version which determined they don’t do anything but add the risk of random melting. That’s simply not good. My virtual hat’s off to Uncle Ted though, as his marketing genius of raising the price on an "improved" (!) version of his latest Magic Fuse (only a year or so since the last version showed up) immediately starts the stampede of the Fuser Faithful to dump what seems to be $600,000 and counting into his coffers…for fuses. You’re realin’ ’em in Ted…well done! |
Look this has been going on and on and gets nowhere. A big "nothing burger" except people hear what they hear. If the fuses make people happy wonderful! Thats what hifis are for. My issue is with the attacks and frankly bullying of those who want to learn and remain skeptical. Kudos to Wolf for standing up to the bullies but at the same time the topic is going nowhere regarding learning anything new or useful IMHO. So what is the point in keeping asking? Now that the designer has chirped in it would seem the time is right to maybe learn something new? So far nothing though. Frankly I’ve never met a good designer who does not love to talk about his work. But why ruin a good thing I suppose. |
Lots of name-calling going on here. I sort of understand it coming from Frank since he is OP and defender of the faith but from you Geoff, stirrer of the pot, I have come to expect more originality. There are many designers/manufacturers here who have shared information about their designs without divulging the Colonel's secret recipe. Even Geoff provides a whole section of "Technical Explanations" on his website, describing how his products work, although I usually take a couple of hits and eat a mushroom before I can achieve an appropriate level of consciousness to even begin to understand. If Ted wants to explain some stuff, then I am all ears and maybe will learn something. If not, or if I only read more about how great these fuses sound, then nothing changes except Ted's bank account. Funny thing Frank, I actually have a Pioneer receiver in my HT system (guilty as charged) so I guess I better get back to that. |
Geoffkait 11-18-2017IMO the explanations that have been cited for the sonic benefits of SR and certain other boutique fuses have either involved measured differences that are much too small to account for the reported improvements (as I have explained in detail in numerous posts in various fuse-related threads here), or amount to **descriptions** of the physical characteristics of the fuse, or how it has been manufactured. A description is not an explanation. An explanation would make clear how the current being conducted by a fuse would be affected in such a manner and to such a degree that it would consistently improve the sonics of components that are completely different in design, that perform completely different functions, that are used in completely different systems, that can have either unregulated or well regulated internal power supplies, that are powered by AC having very different voltage and noise characteristics, that involve both AC and DC circuit applications, and that involve currents that do and do not vary with the dynamics of the music. I would expect that such an explanation could be provided without divulging company sensitive information. As noted above many designers are more than happy to provide comparable information. And in this case a meaningful explanation would, hopefully, satisfy many of the so-called "skeptics," and perhaps even result in a significant number of additional customers. Although I recognize the possibility that depending on the explanation the result could be the opposite. Regards, -- Al |
Al, nice try. The nice legalese notwithstanding. 😄 Nobody including myself or even HiFi Tuning ever suggested the differences in measurements explain the audible differences among fuses. But it is evidence nevertheless. Everybody and his brother except for a few outliers now understands that aftermarket fuses sound better than stock fuses. And we also know SOME aftermarket fuses sound better than OTHER aftermarket fuses, for a variety of pretty obvious reasons, I mean unless one turns a blind eye to them or plays dumb. We also know - as HiFi Tuning states on their web site - that cryo’d fuses sound better than non cryo’d fuses and that fuses CONSISTENTLY measure and sound better in one direction than the other. It’s an undeniable truth. Whoops, except for naysayers. One would have to be pretty stubborn, who knows why, to ignore all the evidence that is staring him in the face. Obviously, it would be a hard pill to swallow for some folk. 😛 Now, I realize I’m going to get a lot of the usual 12 Angry Men reponse, "But you can’t PROVE IT!! 😡 You assume proprietary information would not be revealed? Huh? Why assume anything? As I’ve said before any company who reveals anything is making a big mistake. There is no requirement to do so and it only sets the company up for who knows what. This is not a peer review committee. This is not Journal of Physics. This is not the faculty at Harvard. |
Al, Even if there was an explanation (which there isnt), the obligation to design and build good equipment falls to the audio component manufacturer - that is where the big $$$ are spent by the customer. If a merely different fuse causes an audible change in an audio component’s sound then the logical thing to do is to get rid of the unreliable POS component! Obviously |
Mapman sez: " Kudos to Wolf for standing up to the bullies." I had to laugh ... I've been called a shill, had my credibility questioned, demanded that I expose my receipts to prove that I've purchased the fuses in my system ... and I'M the bully? I've been insulted to no end in these pages and even abandoned the original Red fuse thread in an effort to dump the naysayers who continue to crash through the doors ... and I'M the bully? I HAVE to know how something works and unless I do, I can't be hearing what I'm hearing? For the umpteenth time .... I DON'T GIVE A FIG HOW THE FUSES WORK, only that they do. Originally, I tried one RED fuse and was so taken by the improvement that I enthusiastically shared the results with other members here at A'gon. That's it, pure and simple. To the naysayers ... Get a friggin' clue ... its none of anyone else's business how the fuses work. Denny owes no explanations to anyone. If he wants to give away trade secrets its up to him, but from what I know of Ted Denney so far, he's nobodies fool. My take is that the fuses use graphene internally ... and graphene is known to eliminate micro-arcing. Micro-arcing, like micro-vibrations have the effect of smearing and degrading the sound. And by the way, why no response from dbarger regarding how I attained my fuses? Not that I had to, but I took the time and effort to answer his questions as completely and honestly as I could ... and not even a simple "thank you??" Man, there's some strange folks lurking about. Here's an interesting article regarding graphene: https://www.newyorker.com/magazine/2014/12/22/material-question Frank |
@oregonpapa , don't give them the satisfaction of a reply. If they were in the same room, they'd be high-fiving themselves right now. Their hunger is insatiable and constant. I've been on the receiving end as well and do my level best to ignore them but sometimes you can't let the dumb stuff pass without a comment. Perservere. All the best, Nonoise |
Al, All solid vibrating surfaces generate shear wave interference which alters the original intended signal. All fuses have a solid element which is modulated by the signal that travels thru that element. Circuit breakers and my preference magnets are less prone to modulation and vibration created by the passing of signal. They will generate less interference by design or by material or both. Much of this interference in a standard fuse will be reflected back and forth along the conductor...because of the change in boundary speed and shape at either end of the element. My observations and experience tells me there is more cause to use a improved conductor type on the ac side than on the dc side. There is an audible improvement on both ac and dc ..so I apply to both. By nature there is more noise and therefore more shear wave interference on the ac side than the dc side of things. Some fuse sellers apply damping materials to alter or reduce interfering energy which will travel along the wire.They may not know why. The application of differing damping materials directly to a conductor will alter its shear wave velocity and also the speed at any intersecting boundary. The designer may have noticed a sonic difference when bees wax, is applied to a conductor vs candle wax,soy based or olive based material or a ceramic or a mineral. Any damping material will alter amplitude and frequency. I always search for a work around of any such material or method. Every solid material has a different velocity, a change in material will alter the speed and a change in shape will alter direction and again a change in polarity. These factors and events occur in all audio systems because all the solid materials that make up any system are in a continual state of motion. The fuse element is the most simple of all the solid conductors in any audio system . Its understanding and refinement of application could be applied to all other solid materials and shapes in a sound system. Interferring energy in many devices can be removed with the use of another solid material and terminated with a shape that reflects signal off and away from the signal pathway.Tom |
Wow. I think "poorly designed" is a stretch. There's No Way my Audio Research Reference 6 has a poorly designed power supply. Not in how both transparent and Just How Good it sounds. John Atkinson's measurements of the Ref 6 in Stereophile do not show any power supply defects, either. But I think there is some merit in your thought process, shadorne. A year or so ago, I tried SR Black fuses in my amps at the time, a pair of Ayre Acoustics MX-R Twenties. I heard No significant change in sound from the stock "two dollar" fuse when compared to the SR Blacks. Is that because they were installed in a differently designed component? Or because a preamp has influence over smaller signals than an amplifier? I don't know. When I tried a Black fuse in my Ref 6, the sound was transformed from marginally great to awesome. Also, a Sain Power Systems cord also gave a appreciable improvement in sound. So, in a way, I agree with you. I think the auditory improvements of fuses, in general, depend on the design of the equipment they are installed in. |
Tom (TheAudioTweak), thank you for your sincere, thoughtful,
and well composed explanation. What
you’ve written may be the best such attempt I have yet seen.
However, while I see no reason to dispute the possibility that it might explain the sonic benefits that have been claimed in at least a few applications, when it comes to many or most other applications it seems to me that there are some issues with it:
1)Regarding the following statement … All fuses have a solid element which is modulated by the signal that travels thru that element. Circuit breakers and my preference magnets are less prone to modulation and vibration created by the passing of signal. They will generate less interference by design or by material or both. Much of this interference in a standard fuse will be reflected back and forth along the conductor...because of the change in boundary speed and shape at either end of the element. … As I’m sure you realize, in many circuit applications fuses conduct neither a signal nor a current which varies as a function of signal. Or a current that even varies at all, aside from the repetitive and nominally sinusoidal variation within each 60 Hz AC cycle in the case of mains fuses. The current conducted by fuses in most preamplifiers, most source components, and even fuses in some power amplifiers (if they are biased in class A and provide large amounts of energy storage) has essentially zero variation from cycle to cycle. So I’m not sure that your statement has broad applicability.
2)Wouldn’t the shear wave effects you have described, to the extent they may occur in a one inch or so length of fuse wire and its associated boundaries, be completely swamped by corresponding effects in all of the rest of the wiring in the component, as well as in external wiring such as the power cord, as well as in the electrical parts in the component? As you pointed out yourself: … all the solid materials that make up any system are in a continual state of motion. The fuse element is the most simple of all the solid conductors in any audio system . Its understanding and refinement of application could be applied to all other solid materials and shapes in a sound system. 3)Most fundamentally, what leads you to conclude that the effect you have described, as it occurs in a fuse, would be great enough in degree to have audible significance with the **consistency** that has been reported, regardless of which of the extremely diverse applications I listed in my previous post is involved? In any event, thank you once again for what I consider to be an excellent attempt at an explanation. Best regards, -- Al

I suspect the vibration of walls in concert with seismic low frequency vibration would swamp any micro effects associated with fuses, capacitors, transformers, not that those effects would be inaudible in most cases. That’s why capacitors, fuses and transformers and CD transport mechanisms should be damped - using some effective means, of course, not an ineffective means. That’s also why aftermarket fuses often address vibration concerns, with beeswax, ceramic fuse bodies and such. Personally I like using pure natural cork. Aka Quark! Riddle me this. Why do high end amp manufacturers still insist on coupling the transformer directly to the chassis with BOLTS?! Pop quiz: how many concerns are there for fuses, in terms of signal quality? I’ve just given you one. |
oregonpapa wrote, "My take is that the fuses use graphene internally ... and graphene is known to eliminate micro-arcing. Micro-arcing, like micro-vibrations have the effect of smearing and degrading the sound." Not sure I go along with you on your detective work. For one thing I’m pretty sure the only manufactuer that opens up a fuse, and even then only drilling holes in the end caps, is Audio Magic. For another thing, the issue of micro arcing would most likely be on the outside of the fuse on the end caps, not inside the fuse, where the wire is soldered to the end caps. Also, I’m pretty sure you can see the black stuff on the *outside* of the Black Fuse. That is the Graphene, no? At least. Matrix containing Graphene. Ditto the Blue Fuse if I’m not mistaken, Graphene is on the outside of the fuse. Which of course leads up to my next Pop Quiz. Horray! Pop Quiz, if Graphene is applied to the *outside* of the fuse what the heck is its function? 😳 |
Graphene alone is a superior and faster conductor than copper or silver. If you painted the fuse shell and the endcaps then the fuse would still conduct even while the internal element has melted. You would only paint the endcaps and the the spring clamp housing. In my case I will coat the entire magnet with a graphene substance expecting further enhancement of the signal that travels on the outside while a polarity of shear is disapated thru the core on the inside. Tom |
Here is the skinny from the SR site: " The new SR BLUE Quantum Fuse was developed over a two year period and represents our most advanced UEF Technology to date. At its heart is a completely new UEF / Graphene coating that delivers a dramatic increase in resolution and holographic realism over SR Black. And thanks to a new conditioning process, break-in time is cut in half. In fact a brand new out-of-the-box BLUE Fuse should significantly out perform a fully broken-in BLACK Fuse and it only gets better from there with full performance after 200 hrs of continues power. To find out how good your components really are audition the new SR BLUE Quantum Fuse today. Sold with a no-risk 30-day money back gaurantee. $149.95 in all sizes." So you have 30 days to get the fuse singing in case of buyer remorse. I like the simple color coded model numbers. Its very easy to understand. Marketing genius there for sure. |
That’s only some skinny. Not the whole skinny. Smart move! 😀 Wait! Unless, unless...the wave is traveling on the OUTSIDE of the fuse! What say, Mapman? 😳 And why is the Blue Fuse blue if Graphene is applied to the outside of the fuse? Graphene is black. Or is it? Maybe Smurfs are involved. Or blueberries. |
@imgoodwithtools It is a simple matter of expectation. I expect audio component power supplies to be well designed and well built. My criteria for a good design is that it should be completely insensitive to small changes in incoming power. Like a huge dam across a river - the actual instantaneous flow of the river into the large reservoir lake created by the dam is totally immaterial and irrelevant to the instantaneous power quality generated by the power station below the dam. If your ARC Ref 6 is audibly affected by a fuse then you need to return it for maintenance or ask ARC if they are aware of such a minor detail audibly affecting audio signal output. This is to my mind a clear fault or design error. The purpose of buying high end high quality equipment is to enjoy audio that is completely free of parasitic contamination (from power or other extraneous factors) due to the extremely high quality robust over-engineered design and build. To have a piece of highly engineered equipment with THD+N specifications in the -100 dB performance range and then find out that the sound depends entirely on the type of fuse used - this is pathetic engineering. |
Holographic realism will not be provided by your fuse. The assumption that it can is simply silly, and, by the way, fear of seismic vibration is also a waste of time (sorry Kaitty, almost nobody cares about that), and the only "performance" a fuse provides is the one where it melts to protect things. There is nothing in any "special" fuse that coats the electricity with magic sauce or vibration resistance benefits or anything else that isn’t rendered useless once the raw electric current starts being processed by the rectifiers, diodes, caps, transformers or any other bits of the active power management of any component…if you think your "soundstage" or "holographic realism" is transformed by your fuse, regardless of the degree you overpay for it, you must have an active and easily influenced imagination. Special fuse designers have stumbled on a market almost unique in the world of technology…take an inexpensive component designed to simply provide the stop-gap safety action of melting to interrupt the rush of current that a component failure has caused, ascribe imagined importance to that half inch of wire, and sell it as an active tone enhancer. It's nonsense. The vast majority of amp and component designers ignore the claims of Magic Fuse salespeople, and so should everybody else. Also, way to go Yale! Boola boola! |
Just 20 year ago many couldnt conceive that a 3ft powercord swinging off the end of a mile long ac transmission line could improve the sound of ones system..Whats the ratio of length between a power cord and a transmission line.? Whats the ratio in length between a powercord and a fuse? The glass fuse is a fine line element in series with all the other conductors in an audio system. The fuse element is held in place at either end by the endcaps. To reduce the affects of shear on the overall fuse design all the materials would need to have the same shear velocity. That would mean the element the endcaps and the solder and the enclosure should all be of the same material or at least selected knowing that all these materials have different speeds and their inneraction. The other crucial factor maybe that the element is blunt force impacted by the geometry of the endcap. You will have a polarity of shear at either end of the conductor reflected back into oncoming traffic. Shear changes polarity and becomes more or less reflective with a change in boundary shape and angle. If the shear is reflected in either direction this may explain why fuses can sound better in one direction vs the other. They could offer more or less shear because of production differences from end to end and impurities at the connecting points the impedance would be different and alter direction. Tom |
Op, just responding to you since you seem to be “calling me out”. I haven’t really been paying much attention to this thread. I take it from your response that your blue fuses were free to you, as a beta tester, although you did not actually say that. The answer was kind of vague, so that was just my impression, since you asked. I have no issue with that. Beta testers can be useful. That said, there is a phenomenon of a chef always liking his own soup. Glad you are enjoying your system. |
Actually, there’s more to it. I hate to judge before all the facts are in but it appears to be tit for tat. He gets the fuses and for that he posts his "impressions." That’s a little bit different story. That’s why I said a few days ago, he went beyond the call of duty. SR gave a fuse or two and got a hundred posts or whatever in return. Pretty good payoff. What he said, in response to the dbarger question, in case I’m not interpreting it properly, "....I was grateful for the opportunity (to be a Beta tester for the Blue Fuse). I reported what I heard IN MY SYSTEM ... nothing more and nothing less. Sometimes opportunity knocks at the door and its up to us to take advantage of it or not. One more thing dbarger .... I am also beta testing the "secret and elusive super tweak." We’re almost done and approaching a release date. Has nothing to do with SR .... and its fantastic. I’m on my third version of it and each version is better than the last. Looks like the third time is charm." |
dbarger ... Thanks for the response. I thought you may have fallen off of the end of the Earth. Glad to see you posting here again. :-) geoffkait ... With the exception of the Blue fuses, I've paid full retail + tax + shipping for all of my fuses. Had the Blue fuses been a step back in SQ I would have said so. I have no dog in the fight other than trying to obtain a better sounding system and reporting the results here. theaudiotweak ... Over the years I've had so many "audiophiles" tell me that after market IC's and PC's were nothing but snake oil. Most said that you just can't do better than Radio Shack wire or Monster Cable that one could buy at Home Depot. Then they started on the wall outlets. And then various room treatments. And now the fuses. Same-o, Same-o. Only the names have changed. Wolfie ... The improved perception of 3-D holographic imaging is the result of the lower noise floor afforded by the fuses. When I say "in the room," with good recordings, I mean exactly that. Again, if you're not getting that kind of imaging, there is work to be done. It goes way beyond the fuses though. Are you familiar with the Shatki Holographs? If so ... how do they do what they do? http://www.6moons.com/audioreviews/shakti/hallograph.html I have four of them, each taking up one corner of the room. Take them out of the room and the sound stage collapses, along with the imaging, to the point that I wouldn't want to listen without them. I don't know how they work. Like the fuses, I don't care ... all I care about is that the DO work. Frank |
Same here, both Frank and I have our mutually unapologetically critical friend Robert to thank for his help. He has pointed out (my wife also agreeing) with every tweak and change I have made to my system whether it's better or worse or has no effect. He enthusiastically endorses the Hallographs (he has a pair, Frank and I have two pair) and the SR blue fuses. He says whatever works, do it and get rid of anything that makes our systems sound worse (despite high praise in the trade journals such as the Magico Qpods-yuk)!. I admit I do not have state of the art speakers. They are multi-driver big box type which do not image well by themselves. I have heard more modern speakers which are designed for imaging, especially two way monitors, speakers such as Audio Physic, Focals... The Hallographs allow pinpoint imaging with precise changes in angling the top wood array. 1/8" on my left array makes a significant difference in imaging (for some reason the right one can be 1/2" off and still stabilize the image whereas the pair I use at the mid-room reflection points can be adjusted to up to 1" before they radically alter the imaging). After using Hallographs, I have no need for side and front room audio baffles to absorb and reflect sound (before Hallographs, the room could have used a dozen baffles). They just focus the sound throughout the room. Together. the SR blue fuses and Hallographs create a wide sweet spot and an open, soundstage extending to about a 10' seating area. Great for guests. |
