System that sounds so real it is easy to mistaken it is not live

Please don’t try to state what you not0 even experienced because what you posted about is that you have not the experience to listen true bass down to at least 16hz with out almost distortion and at near 120dbs.

@rauliruegas That is so funny- ROTFLMAO!!

Its funny because you clearly have no idea what you're talking about, which in this case is what I might have done or experienced in my life!

Sheesh  🤣

Dr West often recommends the Atma-Sphere MA-2 for his products and so about 80% of our MA-2 production drives SL speakers. We've shown at CES and THE Show multiple times with Sound Lab (starting back when CES was still at the Sahara in the early 1990s), and gotten Best Sound at Show (Dick Olsher); I've heard Sound Labs with our gear a lot over the last 25 years and I'm on a first name basis with him and others there.

I'm not denigrating Parasound or any other solid state amp in my comments. Dr West did recommend Parasound to anyone who suggested that they don't want tubes. I get that. Of course you know that we have a class D amplifier we've been selling the last year and a half; we get asked if that amp will drive Sound Labs and my answer is the same as if it were any other amplifier:

'It will drive Sound Labs but will not make the power and might seem a bit bass shy simply due to the impedance of the speaker being 30 Ohms in the bass.' That statement applies to all solid state amps that operate as voltage source on Sound Labs and that includes the Parasound (FWIW when I've visited Sound Lab they had a Boulder amplifier).

Now the speaker allows you some adjustment of output levels- it has bass jumpers for changing that level a bit and a Brilliance control. So unlike a lot of ESLs its a bit more adjustable to the voltage response of the amplifier. But its going to be bass shy with solid state amps because solid state amps tend to act as a voltage source.

How this works is the impedance curve of the speaker varies by a factor of about 10:1 from the bass to 20KHz. So its about 3 Ohms at 20KHz (somewhat dependent on the position of the Brilliance control) and 30 Ohms in the bass. It is a little different from other ESLs in that it employs a crossover for two transformers used to interface between the amp and the speaker panel- one for highs and one for lows. So the impedance curve has a bump in it that corresponds to the crossover to the HF transformer. ESLs don't follow the same speaker design rules that box speakers do, starting for the most obvious reason that there's no box with its accompanying resonance.

Here we go. Another thread ruined by the usual culprit.

@atmasphere  : I don't care about your M-2.

My friend never mentioned to the designer that he did not wants tubes ( as I posted he was a tube lover. Even designed  2-3 that he used with his Quad's. ). The SL designer was who gave him the JC recomendation.

I know very well all the facilities of the SL and I really know it. Already know about both transformers, even I mentioned here to mijos. So in what thread are you reading?

Useless your post, at least for me.

I recently attended a Connie Han Trio concert in an intimate room and the drums were so over-miked that it was hard to hear the other players.  No idea why the drums were even amplified.  I need a reason to get out of the house these days and enjoy the atmosphere of live concerts, but overall prefer listening to my home system with a Don Sachs front end, an Aqua LaVoce DAC, and Spatial Audio speakers, where most everything is dialed in.  I control the volume, not the guy on the mixing board.  

@atmasphere ​​@rauliruegas , OK guys, I'm the one who owns the SLs. You are both right and both wrong. Asking Dipole ESLs to make bass causes a lot of trouble. They will do it but it knocks the wind out of them in regards to headroom and increases distortion very obviously unless you only listen to them whisper quiet. Ralph's amps do a better job of driving them but I am still going to cross out at 100 Hz to subwoofers. I am not crossing out of the SLs because I am using JC 1s and am worried about their ability to make bass into ESLs. I am doing it so I can get a clean 105 dB out of the SLs and not be slapping the stators with every drum beat. Roger West knows this and has actually made ESL subwoofers. Last we talked he was making a client subs using 30" woofers.
