Thiel Owners

@unsound,  90 dB at 2.83 V 1/m into 4 ohms means current  = 2.83/4 = 0.7075.  Watts = current x voltage = 0.7075 x 2.83 = 2 watts.  90db at 2 watts, 93 at 4, 96 at 8, 99 at 16, 102 at 32.  Regardless, the older I get the more I'm convinced that the way to go is to have a couple of systems.  My den (I guess you'd call it) has my Thiel system, and my family room has my rock 'em sock 'em robots system.  I'm guessing this is actually cheaper than having a single system that tries to do everything.  I've got around 27k in both systems combined but components going all the way back to 2003.  Less than 2k/year, not an extravagant hobby by any means.

@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.
