Thiel Owners

^With the right amp you can play these speakers pretty loud. Jim recommended up to 600 Watts per channel and used a Krell FPB 600 for them.

When I spoke to Rob Gillum about the robustness of the COAX he said that it was something that should last a very long time. However, he observed that most of the damaged COAX drivers occurred because people thought a $13K speaker can play as loud as an amp was capable.

I blew out my old Revel Salon 1 tweeters a couple of times with my Bryston 600 watt mono blocks. I have learned my lesson of playing too loud.

What this means to me is that the 3.7's are my permanent take to the grave office speakers (not blasting it in the office). I will get something else for my living room.

^Most driver damage occurs when people try to play too loud with underpowered amps.

In the case of my Revels the amps were very powerful, but I do understand your point about underpowered amps.

@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.
