I like all three. If you were running a solid state amp, I could nail this down a bit more but with tube amps, there is more difference between amps. So the best thing to do would be to hear all three and decide for yourself.
With a pretty constant voltage source, I'd probably take the Theater three π speaker for most larger rooms and the two π tower for smaller rooms. That's mainly because the Theater three π speaker is more capable of high SPL. But running a tube amp, that isn't a consideration, whereas the impedance curve might be. The tower two π has less impedance fluxuation, and it really sounds good.
The Thermionic three π has its advantages too. It has a pretty benign impedance curve, which makes it tend to sound good on low power SET amps that might have trouble pushing the bass on other speakers. It also has a slightly underdamped alignment, which makes it provide useful bass response even when power levels are low and/or no boundary reinforcement is possible. This is a good speaker for use with amps like the Zen or in open spaces out away from walls and other boundaries.
Please tell me your E-Mail address and I'll send you the plans.
