Thiel Owners

@jon_5912, It’s been 50 years since my middle school / high school physics classes, but I seem to remember:

current X voltage

_______________ = Watts

    impedance

I’m rounding the 3.7’s as a 2 Ohm load.

Space is the ultimate luxury. I’m envious that you can have multiple quality systems. I agree that’s a great way to approach this hobby.

My pleasure suggesting the MoFi caravanserai SACD.

Happy Listening!

To clarify for those recently joining the discussion, my observations are based on an unusual room that is effectively large since the listening room has semi-porous walls within a 12Kcubic’ space, in a 30Kcubic’ building without many partitions. I also have modified the speakers for 3 separate inputs rather than a single pair. I listen at approx 90dB peaks.

Under those conditions the pair of bridged AHB-2s never clip.
I had hoped for a configuration with a bridged AHB-2 driving a woofer and another one (adjusted for matching gain) used in stereo mode with one channel driving the midrange and the other the tweeter. Alas, the upper amp clipped regularly in my conditions. But, in less demanding conditions that setup works quite well.

"The vertical bi-amp will not work with the Thiel CS3.7 since it only has 1 set of speaker inputs."

Check out bettlemania's system on the virtual systems ,
he bi-wired his 2.4's . 
So with a little drilling and soldering you can have bi-wiring
for bi-amping.

@tomthiel, you seem to be referencing your experience with the AHB2's with the Thiel CS 2 2 's but most of the conversation here is in regard to the Thiel 3.7's.

We can see that while the 3.7's appear more sensitive than the 2 2's, the 3.7's work at a lower impedance. The 3.7's are also recommended for greater power input, perhaps to compensate. The AHB2's would seem a bit more comfortable providing comparable useable power into higher impedances than comparable useable power into lower impedances. Though not conforming to ideal textbook performance, the AHB2's are spec'd to the 2 2's load. However, I think that the crux of this conversation is in regard to the  impedance and the corresponding specifications of the AHB-2's into the load at hand for the 3.7's, for which they are not. The difference between a 3.5  and a 2.4 minimum impedance load is not insignificant.
Forgive me if I appear jaded, but that  "John is adamant that the AHB-2 has enough power. Engineers can be that way." sounds more like he's wearing his marketing hat, rather than his engineering hat.
