I love these speakers. Mine were a gift from an older gentleman who hadn't used them in years. They came with stands and the original boxes and receipts (he paid $900 in 1982). I re-foamed the woofers, removed a thick layer of dust, and carefully re-soldered the tiny wire leads on both mids (1.75" soft domes)....that fix lasted a couple years, but one eventually failed so I tracked down a pair of replacements from a seller in Germany.
I drive them with a pair of Hafler 9290 amps which provide 400-ish Watts in bridged mono mode and they use all of that power.
Speaker position is everything with these....mine sit 43 3/4" from the rear wall, as prescribed by the Cardas method. I was skeptical, but WOW does this work wonders in this case - I think it's because of their open baffle/semi-dipole design. Someday soon I'll re-build/upgrade the crossovers, but they sound amazing as is.
They're paired with a 15" Velodyne Sub (80Hz crossover freq).
People are blown away at the accuracy and soundstage.
