i'd contact john meyer directly about this - as i'm sure ewe know, he's wery service-oriented - (as is klaus, of odyssey). but, i really doubt it's wery complicated - it wood yust inwolve removing the internal x-over, & wiring the separate drivers directly to their respective binding posts. if ewe can operate a screwdrive 7 a soldering iron, it should be no problem! :>) but, as i mentioned before, even w/o going to an active x-over, i tink yule still get better results w/a pair of stratos stereo amps, one amp for each speaker, w/one channel of the amp driving the scan-speaks & the other amp channel driving the ribbon.
hope this helps, doug s.
