Thiel Owners


Guys-

I just scored a sweet pair of CS 2.4SE loudspeakers. Anyone else currently or previously owned this model?
Owners of the CS 2.4 or CS 2.7 are free to chime in as well. Thiel are excellent w/ both tubed or solid-state gear!

Keep me posted & Happy Listening!

Hi everyone--long time reader but never posted. Have loved the Thiel sound ever since I got my CS0.5s back in 1996 which was all I could afford back then.  Gone through several generations from the 0.5 to 1.5 to 2.4 and ended up with a beautiful pair of Morado 2.7s.  After mating them with a pair of Bryston 28B-SST2s, I was in heaven and I couldn't be happier, but in the back of my mind I've always wondered if the 3.7s should be my end game. (That's partly the reason I got the Brystons--they're certainly overkill for the 2.7s, but I've heard they are a fantastic match for the 3.7s.).  That's when I saw Ronkent's ad selling his 2.7s, and I exchanged emails with him re: his thoughts between those and the 3.7s.  He then introduced me to this discussion, and I was blown away!

Over the last few days, I've been reading everyone's comments and not only have I learned so much from this group, especially from Tom (thank you), I was also pleasantly surprised that there is still a loyal following to what I guess I should call the "classic phase-coherent Thiel sound" (as opposed to the current, modern Thiel Audio sound).

Awesome discussion regarding the upgrading path.  Didn't think this was an option until now!  Looks like the 2.7s are last on the list, which is fine because I don't usually like to mess with anything unless I think there is a problem...or unless there is something better, whether it's measurable or even if it's just perceived to be better.  But alas, that's the audiophile's curse, is it not?  To tinker, mess around and upgrade in an endless search for better sound.

That said, I'm guilty as charged, with having this curse!  Heaven knows, if I had put the money I spent on audio equipment over the last 2 decades into Apple, I would be able to retire now, hahaha!  Still, this endeavor makes life interesting.  Again, thank you everyone for contributing to this discussion re: Thiels.  Keep it coming!

P.S. Prof, have you decided to sell your 3.7s or trade them in for another pair of speakers? Last I can recall you were still deciding. Let me know if you end up going with the former route--I may be interested in those 3.7s.
With all the talk about integrating a REL subwoofer and SS2, I’m curious about anyone else’s setup if you have one. I’ve got a Martin Logan Descent that has nice, tight bass complemented well with my previous 2.4s and which hasn’t skipped a beat integrating with my 2.7s. It’s amazing on musical passages and most movies but I have heard other subs, beasts intended to necessitate an annual budget for window repair, that really do sound better for certain blockbuster-type movies. Not ready to give up my ML just yet since these movies only make up less than 5% of the time I use my system.  Of course I would consider replacing it with a Thiel sub but that’s probably lowest in my list of changes. Bass is something I must plead ignorance because I’m not sure I could tell the difference between two high quality subs (unless one is in just another league or serves a very specific purpose like blowing the roof off your house). That said, does anyone else have ML that supplement the bottom of their Thiels? I would be curious how you came to your settings? I know everyone’s environment is different, but would like to know the process itself and if there was anything unique with respect to integrating with Thiels, particularly the 2.4/2.7.
Hi Prof, by any chance are your 3.7s in the Morado finish? While I used my 2.7s in 2-channel most of the time (which had increased after I upgraded my amplification), they’re a component of an entire home theater setup which includes MCS1 handling the center duties (hidden) and a pair of matching PCS in Morado that bring up the surround, and four HigherPlane 1.2 up in the ceiling (painted to match the ceiling). As a result, I wouldn’t be getting any 3.7s unless they are in the same finish.  Looks like a part of the audiophile curse is not just the endless tinkering but also layered upon that limitations beyond budget (of course) and real world restriction such as physical size in a room, color matching, or the WAF.
If they are in Morado, please keep me in mind if you decide to sell to another Thiel fan. If I’m the chosen one, they would be in a loving home with others of their kind ;-)
If they’re not in Morado, then my search for the holy grail will have to continue. I may very well never come across a nice pair of Morado 3.7s again (there was one that came up before I completed my home theater but were long gone before I did), but at least I have a fantastic sounding system as I continue that quest.
hi Jafant,
Besides the Bryston amps, I have a very modest system that was originally tailored for home theater.  It currently consists of Anthem AVM20 as a pre-amp processor.  For source, I have a Sony SCD-XA9000ES SACD for 2-channel but a cheap Sony DVD player, the model number of which I don't know.  Both the Anthem and SACD player have been giving me electrical problems (not turning on a few occasionally), so I've been thinking about getting a Bryston BDA-3 to be used as an external DAC or possibly getting the Anthem AVM60 to upgrade my surround sound processing, either of which I would use the cheap Sony DVD player as a transport until I find the funds to upgrade that.  I've got Straightwire between the Anthem and Bryston amps, with Kimber Kable for the rest of the interconnects, and generic 10awg copper speaker cable I think I got from Blue Jeans.
hi Prof,
My 2.7s are the exact same color. The original shipping box shows the finish as "Morado" but in reality it is Morado Rosewood, and looks just as you describe and matches the image you referenced.  My PCS, while also in a "Morado" finish, is not rosewood, so it has less of a reddish color and is more brown.  In natural sunlight, you can see the difference between the two finishes, but with my recessed lights at night, the Morado finishes look very similar.
Now that I know that your 3.7s are in the same finish as my 2.7s, I know they would fit nicely in my system.  Please consider me when you decide to sell your speakers: batman.fan.ebay@gmail.com
No worries, Prof.  If you decide to trade them in, sell locally, or even to the person who was the first to show interest, whoever that may be, then it was just not meant to be for me to own your pair and the quest will simply continue.  Life is too short to get hung up on these things :-)
Very interesting information, tomthiel, thank you for the science/history lesson.  I've always loved the nice woods that make up the Thiel cabinets, particularly in the x.7s where they actually curve on the side and inward towards the front of the speaker--simply breathtaking!  My 2.7s are definitely the darker, redder version of the Morado whereas the finish on the PCSs is just slightly lighter and less red. Perhaps UV exposure has caused the change in color, causing them to be different?  (The PCS are older and I purchased them second hand.)
Hi dancastagna,
I've got an all Thiel HT setup with very similar speakers to yours (MCS1 center, 2.7s fronts, PCS surrounds, Powerplanes rears, and 4x Higherplanes up top) except for a Martin Logan Descent sub.  It had a much more modest beginning with an Anthem AVM20 powered by their MCA50s: 180watts all channel driven at 8ohms, up to 265watts at 4ohms.  The amps were, IMHO, just adequate to drive the previous 2.4s and then the 2.7s.  I have since added Bryston 28-SST2s to power them and it was a world of difference.  The soundstage improved significantly, which I would attribute to improved upper-range bass response.  It just filled out the image better.  The MCA50s have been relegated to center channel and surround duties, which I think are perfectly fine (except maybe the center but I wasn't about to spend thousands of dollars on a matching Bryston just to power a channel I use less than 30-40% of the time.  Maybe someday...).  Sonically, I like the Anthem and chances are if I upgrade, I may get the AVM60 even though it's no longer manufactured in Canada--they're crafted in Vietnam now. FWIW, everyone who comes to watch a movie at my house are simply amazed at the sound.
As for the sub, the Descent is perfectly capable of movie duties, but I find it better suited to music since the bass it produces is nice and fast.  I've read that there are a few other unique subs that would simply leave others in blockbuster rubble, such as Seaton SubMersive F2, PowerSoundAudio T18HT, and Funk Audio 18.3 (haven't auditioned any of these in person).  But alas, I don't have a budget for both a high end 2-channel system AND a dedicated high end home theater.  Ironically enough, ever since I got the Brystons and opened up the Thiel 2.7s, I've been listening a lot more to 2-channel sound.
Regarding your question on 2 subs vs. 1, the issue of standing waves is much more prevalent with having a single sub.  Depending on your room, it can be a big issue or a small one.  Having 2 subs can really reduce that problem and give you more consistent sounding bass.
Let us know what you end up doing with your system.
Hi tomthiel,
You had mentioned that Jim used flat Goertz speaker cables for the 3.7 development.  If I'm not mistaken, in one of the PCS speaker reviews, he had the reviewer use their AG3 Divinity cables which changed the reviewer's perception of the sound.  These appear to be their top of the line--did Jim use these in particular for developing the 3.7s?  While I don't spend a lot on my speaker cables, I do understand that there is a material difference between silver, which is what the AG3s are made of, and copper.  Do you have any insight into why Jim chose silver?  I imagine he must have used copper and decided to go with silver due to some sort of shortcoming with that material, but that's complete conjecture on my part.
There were a few posts regarding positioning, so I will post my experience.  I started with the Thiel speaker manual and positioned my 2.7s in the beginning about 8 feet apart, 2.5 feet away from the wall, and I sat about 9 feet away.  I noticed that the soundstage opened up a bit more when I moved them a little further apart to about 8.5' (perhaps because I was sitting 9' away) and toe'd them in slightly.  Unfortunately, there are a lot of reflective materials in my living room that I cannot remove, and I can clearly hear the impact it has on the sound (slightly stronger sound emanating from the left side due to reflections).  Sometimes I just like to walk around when I listen to music, imagining the sound stage in the front.  And as others have mentioned, the height at which the ears are make a difference to the sound.  Still, the Thiels do a great job of keeping it centered and broad even if there are subtle difference as I walk around, sitting down or standing up.  By the way, I noticed that the difference between my system and other, cheaper mainstream systems is when I turn up the volume and walk into an adjacent room, the sound is still crystal clear, as if the singer was performing there.  The quality of sound from lesser systems are more muffled and don't project as well.  Just an interesting observation.
I’ve had someone more professional than I come in with a test CD and measuring devices to calibrate my system and adjust settings along with the speaker placement but there are some CDs that just don’t sound as good to me where the speakers are. It may very well be a bias with what I prefer to hear, or a flaw in the testing conditions whereby the test CD doesn’t accurately reflect the distribution of frequencies and audio wavelengths found in the difference CDs I listen to. In other words, I’m sure the placement and settings are ideal to listen to the test CD!
In the end, what matters to me is how I prefer to hear the sounds from each CD from wherever I am sitting or standing at that moment, however inaccurate they may be! That certainly is hypocritical I admit because after all, I love the Thiels for their accurate representation of the material. Could be that I’m ignorant, lazy or just simply human! I am not perfect, despite what I tell my kids.
geoffkait, you mentioned the XLO Test CD.  Did you do the setup and calibration yourself?  If so, do you have any tips?
Come to think of it, I haven't retested my system since I replaced the 2.4s with the 2.7s so it's been over 10 years.  The place where I bought my speakers is who originally came to my home to test and set up my system way back when, but they're no longer in business.  Should I try to find someone else to do it?  How hard would it be to do the testing and re-calibration myself, and what would I need?  I can borrow an SPL meter, standard one from Radio Shack I believe, from my brother-in-law (I think he still has it) but nothing else and no test CD.  What test CDs have people here used?  If someone can point me to a good site or discussion topic that shows what I need and how to set it up, I would greatly appreciate it.  I'm always willing to try something new, or at least take a look to see if it's beyond my capabilities and get someone else to do it!

Hi dancastagna,

I’m afraid there are just too many options, combinations and permutations of pre/processors and amps for you to have a definitive, singular solution. Tom’s advice will certainly help narrow the field, but in the end, I think you will need to audition as best you can the variety of amps and processors to see which one best suits your taste in music and movies.

When I decided to move up from the Anthems, I found that I preferred the more upfront presentation of the Brystons compared to the laid back attitude of the McIntoshes. And there is enough power and synergy from the amps that the music created with the Bryston/Thiel combo just sounds great to me despite the fact that the 28B amps don’t double down from 8ohm to 4ohm. There have been several recommendation from members here as to brands with which you can begin your search. While this can be a huge inconvenience, I find that the journey can be part of the fun...at least before you have to part ways with your hard-earned money!
I would certainly like to hear if anyone has paired their Thiels with a Datasat processor as well, and what they thought of the sound.
I wanted to share some comments from Gary Dayton, who worked for Thiel for 10 years, and is now at Bryston, and here is what he said:

"CS2.7s are very similar to CS3.7s. They don’t have quite the clarity because of the wood baffle vs. aluminum baffle and top. They have a touch more bass though perhaps not as extended.
"My time as service manager for THIEL taught me that the vast majority of people damage their loudspeakers with underpowered amplifiers because they drive them into clipping which sends high amounts of high frequency signal to the speakers that can least handle it - midranges and tweeters. Those drivers then get burned voice coils. Put another way, listening at levels beyond what the speakers can handle is what damages them regardless of power."

Combine this with the fact that my 2.7s has a low-to-average efficiency rating of 87db led me to get the 1000watt monoblocks. I’ve never looked back.

By the way, do you guys remember this beauty, the Thiel MCS1.2?
https://www.soundandvision.com/content/long-awaited-thiel-center

Gary said he did the basic design you see there, but the sample wasn’t even playable. He said "the plan was ultimately to use a version of the CS1.7 woofers and the CS3.7s coax. An aluminum baffle cast like the SCS4 baffle in a bent plywood cabinet."

Unfortunately, the plans were shelved after the new owners changed direction, and he suspects the sample is probably in a dump somewhere. I would have loved to have gotten my hands on it, and work with others here to get it in working order!
Thanks jon_5912 for forwarding the audio consultants list of used equipment. For those interested, I don't believe the HigherPlane 1.2's were ever priced at $2,180!  I think MSRP was around $995 or something like that.  So the price here of $990 isn't a discount at all.  Not to say that it's a rip-off because these are very rare nowadays given the introduction of atmos so getting your hands on some is a feat in and of itself.  Just didn't want anyone here to think they're getting a discount when they aren't, especially for used equipment.
For those interested in cabling, in my discussions with Gary Dayton, he also told me that my Thiels were internally wired with Straight Wire, so his entire system uses Straight Wire. (Not sure if it was specific for my 2.7s or PCS, or just Thiel speakers in general--I didn't ask for clarification.). Straight Wire cables were used in combination with the 3.7/Bryston set-up that elicited the following response from James Tanner, also from Bryston:

"We shared a demo room with Thiel at the recent Vegas Hi-Fi show in January (CES 2008) and used the 28B's on the Thiel CS 3.7's. Jim Thiel himself told me that it was the best sound they had ever had at a show. Also George Cardas of Cardas cables was so impressed with the setup he was sending people to our demo as his quote was - 'that's the best sound I have heard at a show in 20 years'."  Curious how this setup compares to the reference one used within Thiel with the Krell mono blocks and Goertz cabling.  Still, this is impressive evidence of the synergy here.

When I talked further with Gary, he expressed that he uses the Virtuoso R2 interconnects, but he recommended that I reach out to Jerry Willsie from Straight Wire to get his thoughts on my system.  Beyond the interconnects, Jerry recommended Pro Thunder power cables and Expressivo Grande II speaker cables.  While Gary believes Straight Wire take a scientific-based approach and price their cables accordingly, these reference cables Jerry's recommending are not cheap.  For example, the Virtuoso R2 are MSRP at $700/meter and the Expressive Grande are $1450 for an 8ft pair!

Jerry was also very helpful and willing to send cables directly to me so I can audition them for an extended period of time and compare them with my current Kimber Kables.  In terms of purchase, he said that I could keep what I liked and I could pay them, but they typically sell only through a dealer network, not directly. 
Hi Jab,
If S&V were listing them for $1400/each, then prices must have gone up without my knowledge, which is quite possible.  Back at the end of 2013, Crutchfield began clearing their Thiel inventory since they stopped carrying the brand. They sold the HigherPlane 1.2 for 50% off the MSRP of $990, at which point I grabbed a couple.  I confirmed it by checking my order confirmation which I still have.
Also, check out Thiel's press release back in 2007:
http://wircmedia.com/wp-content/uploads/2014/07/Inwall_Onwall_REL.pdf
Again, prices certainly may have gone up since then but the original MSRP was $990 each. 
Hi Jon_5912, if the price is per pair, then the pricing makes complete sense to me!  I must have missed that point, so thanks for the clarification.    
Hi pops, thanks for sharing your experience with SW.  Very interesting indeed!  I haven't spent much time with cabling other than making sure it's sufficient gauge (all at least 10awg).  However, as I finalize all my components, I'm sure I'll reach the point where cables will be the last area I want to investigate.
Thank you Tom for your thoughts.  Your comments that the internal wire is a different animal from the amp-2-speaker one does make me want to revisit just going with SW without auditioning others.  Maybe I should just save up my money and go with Goertz AG3!  Can't argue with the equipment Jim used himself, at least as a starting point.  Do you happen to know why Jim didn't demo the 3.7s with Goertz, but used SW?  Is it because SW just offered to front the equipment and marketing?  Not sure how the industry works...
I whole heartedly agree with you, prof, which is why I haven’t spent much on cable myself. However, when I upgraded my amp to monoblocks and needed longer interconnects, I took the opportunity to get some "better" second hand cables. I don’t need speaker cables that long anymore and as Tom has recommended I will be looking to get a shorter run. However, I’m just waiting to get some good, used Goertz at this point.

The two aspects of cables that would cause me to spend additional money isn’t necessarily about performance, but about: 1) its simplicity, and 2) investment potential.

First, you can argue that cable technology really hasn’t changed since it’s invention, short of better insulation materials. Anything else IMHO really doesn’t improve its capacitance or inductance, and resistance is a function of gauge. (Yes, I’m simplifying this a great deal). So unlike equipment that will wear much more quickly or become obsolete due to change in standards or technological advancements, cables will stand the test of time. It’s not like they don’t age, since copper does oxidize and dielectrics can lose their properties over time, but cables age much better than everything else in the audio chain.

Second, commodity metal prices increase over time. In the ’90s, copper sold at $0.80 to $1.00 per pound. Today it’s around $3. (Silver has been much more volatile, with prices of $8 per ounce in the ’90s and around $60 today. In the early 80s, speculators cause silver to run up to $100, so that may happen again. You don’t really see that with copper.)

Therefore, I am more apt to spend money on a nice set of cables knowing that it would last and I could possibly get my investment back if I sold it. I would also most likely go through many iterations of source equipment, D/A converters, processors, amps, and maybe even speakers before I needed to replace the cables.

But the reason I don’t spend additional money on cables is exactly about performance. I just can’t justify spending $3000 on a pair of speaker cables because I just don’t see the performance lift for the money. Alas, I am not a billionaire playboy like Bruce Wayne. Otherwise, I would get those Goertz AG3s and "speakers that you can hug with your arms and your legs." [reference to Lord Business in response to Bruce Wayne when Bruce said "You’re telling me that you have a machine to control the universe but you can’t listen to tunes and surround sound?" - The Lego Move 2014]
Does anyone know where I can pick up an extra aluminum grilles for a pair of Thiel PowerPlane 1.2s? Do you guys think Rob would have some? I called but he’s out until Monday.
Hello everyone, it’s been a long time. Lost my job and finally got a new one, so my audiophile hobby was put on hold. Had a chance to dust off my system and start listening again. Man I love good music and good sound!

Curious if there is a sonic difference (improvement) when adding outriggers, or it is merely to stabilize the speaker? In particular, does it change the sound from my 2.7s? I got them used a few years ago and the original owner didn’t have any but if there is a difference, I might try to track down a pair, perhaps Rob might have some?
Also, is there a difference in sound (again improvement) if I use the stabilizer feet that does come with the speakers in case I can’t source any outriggers? I apologize if this has been discussed previously or in another thread. If so, I would greatly appreciate a link to them. Thank you for your thoughts!
Thank you Warren, ronkent, jafant, brayeagle, prof and especially Warren and Tom for your thoughts. The insights here on this site coming from the forum members is incredible, and I always learn more than I ever think possible. I knew stability was one improvement from the feet but just reading about how that translates to sonic changes helps me understand the subtleties beyond what I believe my ears can discern.

Regarding the bottom of the 2.7s, they are indeed flat but my tile floor is not, so the right speaker is a little wobbly but the left speaker is fine. I put on the feet (atop isolation pucks) which has improved stability but because the sides of the speaker curve inward to the back, the rear feet are close together so the stability of the speaker is a concern of mine, especially since I live in earthquake-prone California! In fact, I was doing some dusting when I lost my balance and nearly knocked one of them over--which triggered a chain of thoughts about the sonic impact from changes to speaker stability and elevation. At this point, I think I might try to obtain a pair of outriggers to see how it impacts what I hear. If anything, it would improve the physical stability of the speakers--and that alone would be worth it to me.

By the way, I really enjoyed reading all the articles that members have forwarded here about the demise of Thiel Audio. Very interesting!
Thank you brayeagle—got those 28s used! I will definitely audition the BP17s, thanks for that suggestion. I also took a quick look at the SP4s and while the specs look incredible, I just can’t drop that much coin on tech that seems to change so much. @Prof, I’m actually very much interested in looking at options outside of Anthem and Bryston, and hopefully I’ll get some more feedback on what people have liked with their SS amps and Thiels. I’m a little nervous getting into tubes as I’d just be a noobie in that area. I don’t know how long they last, if tubes need to be replaced often, they look so delicate, are used tubes reliable, etc. Certainly this fear comes from ignorance and I’m the first to admit that I’m probably going to just stick with what I know and have used in the past: solid state. That said, if I can find more time to lean about tube preamps and can save up some money, I may venture into this arena. @Prof, what preamp do you use?
Hi Everyone,
My Anthem AVM20 pre/pro that I’ve had for over 15 years has just died. Originally, I was using my system for 75-80% HT and the remainder 2-ch. since then it’s now about 50/50. I’m looking for some thoughts on a pre/pro or preamp that has good synergy with my current setup, which I have slowly upgraded:
- Thiel 2.7s
- Bryson 28B2 monos
- Goertz Alpha Core AG3 speaker cables and Straightwire ICs
- Sony SCD-XA9000ES sacd player
- A dead Anthem AVM 20
- Martin Logan Descent sub
- and some cheap Sony blu-Ray player the model of which I can’t recall, lol!
I’d be open to going with a stereo preamp right now given that there seems to be a lot of change with HT at the moment with the evolution of object-based surround sound. In fact, I was originally going to get the Anthem AVM 60 but then Marantz came out with their 8805, then Emotiva with their RMC-1, and soon Monoprice with their 16-channel option...its enough to make my head spin!  Let me know what pre/pro or preamp you guys have heard (or possess) that has sounded good with a similar SS setup!
Thanks @holco. Never heard of Audio-gd, but am open to taking a look and will look at their products.  The price is really reasonable.  Has anyone else here used their preamps or DACs?

Thank you for the suggestion, jafant. My brother is starting to get into the hobby, despite my warnings of endless tweaking and empty pockets, hehe, and I may end up giving him my 9000es.  (Will tell him to stock up on parts.) Been looking at going all digital, but I don't think I've done it right--the SQ seems weak.  Not sure if it's because of the Anthem DAC, or perhaps the source.  I've been using my Mac Mini and ripping CDs at ALAC (Apple's lossless codec).  Perhaps the SACDs just sound so much better?  I didn't think there is an audible difference, so I'm thinking it's something else.  Either that, or its just the synergy of the 9000es SACD player with my system.  Will continue tweaking.

For those who have gone all digital and find the results acceptable (or preferable to physical discs such as CDs or SACDs), what have you used from source to the amp?  The Thiels are famous (or notorious) for being very revealing, so it's most likely sounding out a weakness in my chain from source to amp (don't think it's the amp to speaker).  Appreciate everyone's thoughts.
I’m struggling to make a decision now that my pre/pro is dead. Lately, I’ve become interested in digital delivery, both storing media via a NAS and streaming. I still have a CD collection but the digital aspect I find extremely convenient, especially as it relates to new music.

I don’t mind investing in equipment that would last a while, such as my 2.7s, Bryston 28Bs, Alpha Core AG3 speaker cables, and Straighwire ICs (since I don’t see myself replacing any of these). However, I don’t want to spend much money on things that change quickly, like certain technology and digital standards.

What do people think I should invest in and which things should I stay way from. For example, do DACs change often? If so, should I invest in a good preamp but get external DACs that I can swap out as technology changes? Appreciate everyone’s thoughts.
@Tomthiel, what did Jim use as a preamp when developing the CS3.7s, do you know? Were there certain brands or types (tube vs. ss) that he gravitated towards?
Hi Everyone,

3.7s owners I would like your feedback.  What is the minimum size room you think is appropriate for them?  I'm not asking for the optimal size, but one whereby if you went any smaller, it significantly damages the ability for the 3.7s to image properly.  If you've moved from a 3.7s to 2.7s (I think that includes you Prof if I'm not mistaken), or moved from 2.7s to 3.7s, I'd be particularly interested in your thoughts.  I've got a pair of 2.7s and there are a couple of 3.7s on the market that are whetting my appetite.  The 2.7s are perfect for my current listening room right now but we're in the process of moving so I'm curious as to what size room I should have to fit a pair of 3.7s appropriately.  Not sure the wife agrees with my priority list for the new home though:
- Short commute distance to work
- Quality schools for the kids
- Properly sized listening room for 3.7s... 

Tom,
Curious when Jim was developing the 3.7s did he use a particular room for listening/voicing them?  If so, what size was that room?  Or was not a part of the equation?

Sincerely,
Batmanfan
Thanks for your comments @tomthiel. I am not familiar with the process of developing speakers so the description you gave of the engineering chamber where speakers were put up with tweeters 10’ above the ground made me imagine the Bat cave with Thiel on pedestals, lol!  I learn so much in this thread, thank you everyone.

Anyone other thoughts, especially from those who own (or have owned) 3.7s and/or 2.7s regarding the minimum size of a room for a pair of 3.7s? If you do provide dimensions, please let me know what assumptions you’re apply, such as how far into the room the speakers are placed and how loud they are played. Thank you!
