Oh, I think he was just bumping to get me to tell what op-amps I use in the crossovers. Back when I got them there were several choices, depending on how much one wanted to spend. I was hoping to ignore the thread, because I have to move a small table and see if the crossover has enough service loop in the back to pull it out and get the lid off. Then I can see what I used, since memory completely fails me. Maybe later this afternoon!

Ok, I took it apart. FWIW, it's stuffed with AD712. I think that was good then and ok now. Probably there's a National LME amp that would be a bit better.

exactly why im only running 2 15 watt amplifiers per speaker, mini a's im running matched drivers ( not manufacture ) but spl and efficancy 91's for the ribbons and 91 for the mid bass 6.5"

Love it, so many people need to have HUGE power amplifiers and i have these tiny little things and such free and clan sound.
