I'd forgotten about Linkwitz ! Back in the 80's I used an adapted version of his active crossover design (from the Wireless World article) to set my speakers up with one amp per driver. One mono power amp for each bass driver, and a pair of smaller stereo power amps, one for Left mid and tweeter and the other for Right. The speakers were Yamaha NS100M's and driven like this they went LOUD...
I'd say that the sound when driven in this way was hugely transparent, especially since any distortion arising from the bass amplifier was kept to the bass speaker unit instead of ending up in the tweeter via the conventional crossovers. Driving the units directly is a much easier load for the amps since the inductance of the crossover is out of the equation. The lowest frequencies were extended with some equalization in the active crossovers. Eventually both crossover boards and one of the stereo power amps died after a nearby lightning strike, and I reverted to the original passive arrangements. The speakers are still going strong at nearly 30 years old... now where's that soldering iron :) -- karma mechanic ------------------------------------------------------------------------ karma mechanic's Profile: http://forums.slimdevices.com/member.php?userid=8868 View this thread: http://forums.slimdevices.com/showthread.php?t=31557 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
