This turkey don't fly!
Actually, while it looked good on paper, my adventure of the AES on top and the Odyssey on bottom did not work out at all. It was an obvious mismatch either from gain or impedence (never got an answer to my orignal question but tried it anyway). Integration was awful with booming bass dominating the show.
Oh well - time for Plan B. Does anyone know of a really good Subwoofer that can integrate musically with planar type speakers (Newform R645's) and Tube Amp's?
