Has anyone tried double CLS

You guys are all talking unproven nonsense. I am reporting the facts as I actually am living with doubled CLS11Z at the moment.Not a flight of fancy.Until you hear or try this you are just speculators.Now to get back to the real facts and truthful description of what is happening with double CLS.To begin with there are no cone speaker matches for any Stat that do any more than add disconnected bass.This is where things can really get nasty.Way back when, Harry Person substituted the Hartley cone subs for the panel Magnepan Tympanis,he got more realism and a better match to the speed of the stacked Quads.I used to own single esl 57, heard a stacked pair in Montreal, realized what I was missing and found another pair ,made the stands and away you go.It is all about the radiating area of the speaker.Anyone out there remember the Acoustat with the servo tube amps? The more panels you added,( up to 6 per side per amp)the easier the amp ran the more bass you got and the more effortless sound,the only limiting factor was room size. These are not stacked arrays,but multiple panels, side by side.This is what Kimber did at RMAF, they are not stacked,the speakers are 8 feet tall un stacked.
I have been at this game for over 30 years and I have owned the stacked 57, single 63, Acoustat 3 panel(unamplified)ML sequel and single CLS, CLS with Depth sub and now double CLS.I can tell you from real exposure to all these combinations, that the sound I have now is light years ahead of anything I have owned.Forget the subs and stands,for what you are spending you could have bought an extra pair of CLs and then know what I am talking about.

I must repeat, the double CLS are not stacked so you do not need ceilings any higher than you need for a single pair. The speakers are wired in series exactly as the gentleman has described and the load to your amp is not as severe as with one pair.You only need to find a used pair of CLS and 1 extra speaker wire per channel( I use 6 separate 3 foot wires)This is a very inexpensive,upgrade that anyone can perform. There is no external crossovers, no extra sub woofers and interconnects, no pain in the ass positioning of a sub to where it sounds best( like I have done trying to get The Depth to disappear)no soldering wire, replacing or upgrading internal parts or connectors,no power supply upgrades,no power cord upgrades.None of the things audiophiles spend small fortunes on trying to improve their sound.If you find a used pair in the $1000.00 range that is the least amount of money for the most improvement you will ever make to a single CLS system.No expensive time consuming learning experience here.The fun and the proof is in the pudding. And in putting together a double pair.I would feel grief to those who spend five times as much money and effort futzing around with power cables and speaker wire upgrades in a vain attempt to better the sound of their single pair.Good grief, don't knock what you don't know and have no hands on experience with.Do you still think that if man was meant to fly he would have been born with wings?

The more panels, the more radiating area the more sound.Is this too hard to comprehend?The stacked Quads didn't magically have any different bass than they had before.They did not go lower.The bass just radiated into the room more so that you did not feel the need to augment it in any way.This is what I have found by doubling up on the CLS.My claim is that there is more bass, not deeper or different sounding bass.Just more bass power ,if that is easier to understand.The bass no longer feels like the poor country cousin.There is more bass loading the room.Would you have us believe that an Acoustat 2(2 panels per side) has the same bass energy as an Acoustat 4( 4 panels per side)?Yet this is your argument that an extra set of CLS will make no difference. The basic principal involved is air movement.More panels more air movement.More sound in the room is generated by 4 CLS as there is by 2.This is like saying that the panel sound from a pair of Aerius is no different than the sound generated from the Summit panels. It just isn't so in the real world, or in my listening. Larger panels, more sound.Four panels equates to more sound,and there are no problems.Addition and subtraction nodes?You should get some hands on experience and not postulate wild assumptions.What about the nodes created trying to pair up woofers and stat panels?Why do you think that most stacked or doubled up Quads systems don't have subs? I am sure there were a lot of people who said it was blasphemy and that it just wouldn't work as well.In any event,this set up works for me and it will for those who try it.

I think you don't know much about the Quad ESL.There is one treble panel in the centre of each ESL 57,flanked by a bass panel to either side. Three panels per speaker only.
So when you stack you get 2 treble panels and four bass panels per stack.You get more of the bass into the room this way and the result is you do not feel the need to add on subwoofers,neither do you need a super tweeter.When you add the subs and super tweeters you change the sound of the Quads and move into territory that is frought with problems,beaming tweeters, booming bass.Talk about room node problems. Doubling up on Quads or doubling up on CLS is not meant to change anything about the sound of either speaker, and I have never claimed it would.It is all about delivering more of the sound you liked about the speaker in the first place.

To quote from issue 67 of TAS"a pair of(Classe) DR 8's sends 350 watts into 8 ohms,and 525 into 4 ohms"So I think my Classe DR 8's run in balanced mono are quite up to the task of driving my CLS even as a single run. Now when the amp sees the series set up the power output would drop some, but the increased wave launch from the extra panels makes watts a moote point and the amp sees an even more friendly speaker impedence.Forget the Speltz auto formers,not needed.I hate to beat this thing to death but I am the guy who lived with these without the sub, then with the Depth and now doubled up pair.The difference is amazing and the 80% acceptance factor goes up another 10% at least.The only time this makes sense is when you do it. Then you will insert your foot in your nether regions for not doing this before,and for trying all the "audiophile approved"expensive fixes.I am stating, you will never get a cone sub to mate with a stat.The closest the Quad 63 got was the Gradient dipole and it was not perfection.The Depth is a good sub ,I have one remember,but it is not a panacea for this or any other stat.Stats need planar bass panels to keep the music coherent.This is much more serious yet it appears not to mater to the naysayers here,who have not tried or heard a double pair,and have had little exposure to very many stats as is evident from the threads.There are NO Cancellation or Phase problems!The speakers disappear,it is a seamless integration,coherent,more music occupies the room, yet they aren't louder.More bass is present- not louder, deeper,out of phase,added on bass, but the true panel bass of a single CLS is increased. There is the same bass sound, but more of the room is filled by it so you don't notice that the speaker is bass shy.I have run out of ways to explain the benefits of a double CLS set up,and if I were wealthy enough I would fly the doubters here for a listen, because you have to hear the improvement for yourselves.
