Thiel Owners

@unsound  I'm not sure why any single-driver cone speaker wouldn't deliver reasonably accurate step and impulse response.  Sure, they may be compromised by dispersion, frequency extremes, SPL limitations, but so long as they're free from a crossover and, ideally, sealed or open-baffle (ie no port tuning), I see no reason for them not to mirror the amplifier's time response within the limits of their motor and diaphragm assembly.
   I see why large single-panel planar speakers may be compromised as you describe.
   Headphones are apples and oranges to me.  Two very different and equally valid listening experiences, especially with the relatively recent advancements of higher-end headphones and dedicated amps.  YMMV.  My only point was that nearly all headphones are perfectly time- and phase-coherent, with none of the compromises required by single-driver  or Thiel-like multi-way speakers.

So here’s the thing if I get the cs 7 my 3.6 have to go. Guy said they’d give 500 on trade in for the 3.6z with me selling my car. I’d be able to do this.

Classe model 25 should work on the 7 after all I see videos of them being used on apogees

@sdecker , You’re point is well taken , which is why I went back to check again. I wasn’t sure how  the whizzer’s were implemented. In the case of the Tannony’s there are indeed  cross-overs, they’re not 1st order and the step responses clearly show they aren’t time coherent.

@thoft, the 3.6’s are probably already too big for your room, I think the 7’s (as good as they are) output, will overwhelm your room. If the 3.6’s are in any kind of decent shape, should garner well over that figure on the open market.
This all seems akin to one living in an apartment, struggling to feed themselves; considering buying a horse as a house pet.
