While I am refinishing my Altecs, I just purchased a Crown microtech 600 amp to drive them
coupled with Behringer FBQ 3102 dual 31 band equalizer
connected to a Pyle PYD 1270 2 bus mixing board.
And a QSC 1400 amp to run my old 18" Bullfrog sub.

I cant wait to hear hear them run through this setup.

So far I have only run mine through a Peavey 400 mono mixing amp, and am totally impressed with the sound.
