Nice system. How do you power the open baffles? I see they have their self-powered sub, so the amp feeds the 12" mid and AMT.

I'm interested because I was thinking of a 2A3, but then took a turn towards open baffle and I'm thinking it won't have enough power. But if it can drive you 97dB OB maybe there is hope for me.

FWIW, I believe we have the same horn-loaded AMT, open back.
