Thiel Owners

Happy Friday ! All

Ok just tried 9 apart, indeed much better than 8 much more air between the instruments, sounstage is spectacular.

I have best results with very little toe in.

I cannot try 10 apart because my carpet is not wide enough but very happy with 9.

 In the next few years i should be able to have a dedicated room and therfore everything will be done for the system, 10 apart will not be a problem.

@Thieliste, Same here, long wall. I personally prefer long wall placement. I find imaging and bass response often improves with such a layout. But again, absorption directly behind the listener is required to avoid comb filtering. Even if it's just a temporary item used only during listening sessions. Also, pulling the speakers well out (>3') from the wall behind them will help with clarity. 

If using spikes, I suggest removing them while experimenting. Replace them when ideal positioning is established.

9' could be ideal, but don't be afraid to try wider. Especially with such available space from side walls. Just a slight tick of just a couple of degrees of toe in could easily compensate for the foreshortened distance of listener from loudspeakers. It might really open up the soundstage. Keep in mind the center of the woofer's relationships to the various boundaries. Experiment! Test recordings can speed up the process.

Good luck!

@unsound Yes seems that we have similar rooms, my system is long wall placement and i'm sitting close to the back wall about 9 feet from tweeters.

My room has very good acoustics as i have wooden floor, thick carpet under the system and thick curtains.

I use my dad's paintings as absorbers on the walls and furniture.

I'm lucky to have a wife that let's me use the living room almost like a dedicated listening room lol

I will try 9 feet apart and see how that goes.

8 feet apart and 10 feet to you , 

if I recall that is what Tom said this is the spacing he used for testing his mods . 

2.7 manual is 8ft apart and 8 to 10ft to listener , min 3 feet speaker center from side walls and 2 1/2 from front wall to rear of cabinet

toe in should be used only if you can't meet the min. to side wall spacing ,

I can't be 10 feet from the speakers , so I used the triangle formula of 8 x 10 x 10 this gave me an angle of just less than 48 degrees to the listener , my speakers are 84 inches apart and 104 inches to listening position , 37 inches to side walls and only 28.5 to the front wall .

So if you can sit further than 10 feet from the speakers  you can experiment with moving the speakers more than 8 feet apart keeping the same angle to the listener

^Thiel measured their speakers from a distance of 3 meters (approximately 10’), and a minimum of 8’ is required for driver integration and time alignment, aimed straight ahead. If I recall correctly, the 3 meter distance would have a convergence of 22 degrees behind the listener. As space allowed, close to an equilateral triangle for placement was recommended. So, in a room with available side wall space (at least 3’ and preferably 5’ or more) closer to 10’ apart center to center. As you have more than 5’ to side walls, closer to 10’ might work and provide for a bigger soundstage. The distance to listener is another variable to consider. If placed 10’ apart (center to center) and you have less than 10’ between listener and speaker, a bit of toe in might be needed. Toe in can be tricky, just a little bit goes a long way. Too much toe in, and you can shrink soundstage and perhaps even worse, introduce brightness. Another consideration would be the distance of woofer centers to front, rear and sidewalls, and though obviously less controllable, floor and ceiling. The ratios of which can be important for smoothing bass frequency. Simply put; it might be best not to have even multiples or divisibles of any of those distances.

FWIW, as I set up my Thiels, my room affords similar wide space between speakers and sidewalls, but regrettably doesn’t offer quite the ideal distance of listener to speaker. So, I set up mine 10’ apart (center to center), 7.5’ from center to sidewalls, cabinet backs 3’ from nearest wall, and a speaker to listener distance of 8.5’. with 2.5 degrees of toe in. If your room is similar to mine in that the back wall is close to the listener, I can’t emphasize how important some absorptive room treatment behind the listener can be!

Every room is different. Use the figures as a starting point and customize as necessary.

Hi guys, just a quick question regarding positioning.

How far apart were you able to set your Thiels from tweeter to tweeter without having a hole in the soundstage ?

Is it 9 or 10 feet or more ?

I have my 3.7s 8 feet apart as recommended in the owner's manual and pointing straight ahead as i have a lot of room from the side walls around 6-7 feet.

^It's not like it was when Lana, Dawn and Shari were there to pick up the phone.

Too bad. :-(

orchardsound

Yes, the website route works. That is how I got in touch with him.

Thanks, Tom,

So, the website route works then?

orchardsound - don’t take it personally - he can be hard to get.

What's the best way to contact Rob Gillum? I have a pair of Thiel CS 2.2 in need of a little TLC. I bought them new ~'93 and I've always liked them. I still have the original boxes! I sent a message through the website a couple of days ago but haven't heard a response. If he's still working out of Lexington I could just drive up and drop them off, I'm only a few hours away.

dseagle03

Welcome! Good to see you here. Give Rob some time to respond. He is a 1-Man operation.  I look forward in reading more about your Musical tastes.

Happy Listening!

First post! I have been following this forum for a couple of weeks and have been fascinated and overwhelmed with all of the information. I have a pair of 2.4's and 2.2's and have already emailed Rob Gillum about the 2.4 upgrades. This is exciting stuff.

vair68robert - I would also love to hear anyone's feedback about this wire configuration. Anybody have any experience and/or theoretical hypotheses?

Maybe it's my imagination but it seems like there's way more Thiel than usual on ebay right now.

PM sent.   Happy Listening!

I was happy to hear that @thieliste 's speaker shootout declared the Cardas Clear Beyond speaker cables the winner being an owner of Cardas cabling .  But for most the cost puts this out of reach for an average guy . While I tried and didn't succeed in using Cardas 9.5 awg ( the same used in the CCB ) in different configurations , parallel single runs , twisted and used as the negative with Cardas Neutral Reference used as the positive , I'm still always interested in speaker cable designs . The Cardas web site shows the Clear Beyond as a quad star but describes it as an octo star ? But at least they give you more information about cable designs and specs than most other manufactures .

Duelund conversion to DIY Helix Geometry Cabling  after reading this thread I've become curious about this design , are any Thiel owners using or have tried this design ?

Thank You for citing Transparent cables for your Esoteric player.

Happy Listening!

Well it is surprising but the Humboldt had much more grip than the Diablo 300 on my 3.7s.

Bass was much deeper, detailed and full body with the Humbold, the Diablo sounded lean compared to the Humboldt.

In Europe the Humboldt’s MSRP is 42K, i cannot think of any separates that could compete within this price range.

Well you don't need a degree in physics to determine a 600 wat amp will fill a room easier than a 200 watt amp with siliar amp output to fill a 21,000 cubic foot room 

duramax747

Right On!  Spec(s) are a starting point. Still, numbers do not tell the whole story.

Trust your Ears.

Happy Listening!

I have the 2,4 and when I use mu XA200.5 with them they are a different speaker. 

I use the X600.5 for the 7.2 as they just have the power to handle that load and play in a 35'x60' living room. 

^Interesting. For $55K the Humboldt's specs don't impress, especially for a load like the Thiel CS 3.7's. The Humboldt is rated for 320 Watts into 8 Ohms / doesn't come close to doubling down with 460 Watts into 4 Ohms and is not spec'd into 2 Ohms at all. The less than half the price Diablo on the other hand is rated for 300 into 8 Ohms doubles down to a greater and more linear response of 600 Watts into 4 Ohms (the CS 3.7's actual nominal load) and 950 into 2 Ohms. With the CS 3.7's 4 Ohm nominal / measured 2.4 Ohm minimum load and recommended power of 100 - 600 Watts (into an 8 Ohm load, with the understanding that the amp could double down as necessary) the Diablo appears to be better suited. For much less than $55K one could easily find separates with more apparent appropriate specs.

I had the proof that Thiel speakers are not the bottleneck in a system when i compared my Gryphon Diablo 300 to the Audionet Humboldt in my system.

My Diablo 300 felt like a broken amp compared to the Humboldt driving my CS 3.7s.

That's how much of gap there is in sound quality between the two amps, insane.

I will keep on upgrading the pre-power part of my system for sure in the future.

^Not all Pass Labs are suitable for all Thiels.

gcarlton

Good to see you here again. Agreed, Pass Labs and SR cabling are sonic matches for Thiel Loudspeakers.

Happy Listening!

I have cs 2.4 speakers I bought 15 years ago and mated with an old integrated amp. They always sounded just ok and i stopped listening 10 years ago.  I just picked up a new pass labs int 60 with an acoustic zen Krakatoa and level 4 synergistic research speaker cables. Finally, I have equipment that allows the real sound of these wonderful speakers to be heard.

Pieper - Thiel drivers are all highly serviceable. FF can be removed and replaced. Your speakers can live on. 

Sisters should be speakers..

@jafant yes, the tweeters in the cs2.4 have FF.

I know because I have a slight difference in openness between the two: and Rob Gillum told me that this is either due to some electronic problem (which sparked me to do the upgrade in stead of selling the speakers (I had them on eBay for a day or the, before deciding against getting rid of them..).. I have received my Fluke measuring device yesterday and have still to see if both sisters have the same values), or this may be due to a difference in the amount of FF in the tweeters....

If it's electronics, the problem is solvable. If it's the amount of FF there is nothing to be done... 

Y'all have a nice weekend👍🏼

Happy Friday! ALL

I just got a great deal on a pair of CS3's. Just 3's no dot anything. They sound great. I found out that they originally came with a bass equalizer. I bought one "working perfectly" on ebay, but, it is problematic, scratchy. I brought it to a shop recommended by my speaker repair place.

I mentioned to the tech that I believed it was only used to boost the bass of the 8 inch woofers, but, he led me to believe that it did more than that, almost like it was constantly monitoring the signal and adjusting it accordingly.

Sounds to me rather impressive for a "black box" .... any info on this?

Thanks!

77jovian

My condolences to your friend. I hope that he can recoup all that has been lost.

Happy Listening!

I had lunch this week with a friend of mine who lost his home in the Marshall fire in Colorado.  It didn't occur to me until we talked that, among his losses, were his Thiel 2 2's.  Sad day.

tomthiel

Thank You, as always, for being on-point.

Happy Listening!

jafant - Yes

The CS2 is the Dynaudio D28AF or later D28/2 which are Ferro-Fluid units.

The CS2.4 coax (I've been told, but not certain) is also F-F

Note there are many different formulae of F-F and only the correct one will keep the original parameters intact. Note also that a specific amount must be used.Too much will roll off the high end and too little doesn't give enough heat protection.

Rob is quite expert, I am not.

tomthiel

Are the tweeters/coax in models CS 2. or 2.4 filled with Fero-Fluid?

Happy Listening!

thieliste

Thank You for citing the Cables in the shoot-out. Cardas certainly had stiff competition. I have always wanted to demo Kubala and Tell-Q cables/cords.

Happy Listening!

@jafant My Gryphon VIP series SC and IC went against Odeion Sigma, Kubala Sosna Sensation, Cardas Clear Beyong and Tellurium Q Statement.

The best all around cables in my system were the Cardas Clear Beyond and therefore ordered them, should receive them whithin 3 weeks.

My Gryphon VIP series are up for sale.

Arvin - congratulations. The KEF Blade 2 is a magnificent piece of design and engineering. It does a whole lot right and I hope you enjoy them thoroughly.

Of course, it doesn't address time or phase, so I trust that you have figured that in your equation. Some Thiel fans get hooked on the coherence stuff and 'don't know what they've lost till it's gone'. (a la Joni Mitchell)

@arvincastro , Good luck, enjoy!

tomthiel

Thank You for the update. Good to read that Progress is being made.

I hope that Rob is doing well as CSS.

Happy Listening!

thieliste

which Cable models were in the shoot-out? How many days/weeks were involved?

Happy Listening!

arvincastro

Nice score on the KEF Blade 2 loudspeaker. Enjoy the Music. Stay well.

Happy Listening!

Hello, all!

I know it’s been a while since I last posted/contributed, but I have certainly kept up by lurking in the shadows.

It is with some regret that I will no longer be a Thiel owner as of tomorrow.  Earlier this afternoon, after a couple of months of toying around with the idea of replacing my Thiel 3.5’s, I was presented with an opportunity that I couldn’t pass up and bought a new pair of Kef Blade 2’s.  I find it fitting that I’m moving on from a speaker that was among the references of its day, to one that has been universally acclaimed as a reference performer, with state-of-the-art design and engineering of today.

I want to say Thank You to jafant, Tom Thiel, unsound…all of you.  I learned so much and truly enjoyed all the interaction.  This thread remains such a shining example of what a forum should be about…and it’s all because of the posters here.

I will continue to lurk, continue to stay notified of new posts, etc.  I may no longer own Thiels (for now), but I still want to be associated with fine, fellow audiophiles like all of you.

Thanks again and stay well…Enjoy the music!

Arvin

Hi guys, i finished my cable shootout in my system and the winer is Cardas Clear Beyond.

Just ordered Clear Beyond SC and IC.

Best balance between high resolution, organic sound and huge slam.

@tomthiel thank you for your cable update.

I would be interested in a workable configuration.. 

Got half the things I need for my speakers.. so good to get started soon...
