  1. I have read a few threads regarding Kenwood's classic KA 8006 and the fact that there is no pre-amp output. The output is a full pre-amp level without volume/balance control. The output is used for a QUAD generation setup. If you are into QUAD, there ya are. But for and ol' skool stereo rocker who is looking to bi-amp speakers, it worthless. Without a little tinkering. And I tink. The Kenwood KA 8006 is a pretty gnarly integrated amp in its own right. But you have to make a modification for the pre-amp output. Output to an electronic crossover such as a DBX-223, the high output back into the Kenwood to power the tweeters and the low output to my ol boat anchor Phase Linear 400 And those drive my Wharfedale 8 Need Help?

  2. I'm planning to tri-amp (probably) or bi-amp (maybe) my system which uses TSW-410's. I need better bass response, all the way down to 20hz or lower, for playing my digital piano (which uses Pianoteq model). And I'm intrigued with advantages of the individual amps... I think I will use Marchand analog active crossover network, which won't have any latency at all, unlike a digital processing approach. (Even small amount of latency doesn't feel right, on the piano.) I'm considering a nice 15" Dayton hi-fi woofer with amp, crossover to the AR woofer at about 100hz. Then disabling the AR crossover between woofer and mid/tweeter, using the Marchand for crossover freq about 440hz, similar to what I think the AR was doing. But I'm not sure what slope to use. I think it may depend on whether a speaker response is starting to roll off at around the crossover point. A Dayton RS-HF 15 woofer is good to 800hz I read, and the AR 8" is good down to 50hz or so. So not much roll-off around 100hz. Can I use a 24db/octave slope at 100hz, or is that too steep? And then at 440hz, I'm not sure where the 8" woofer rolls off, and I wasn't able to look up the slope of the existing TSW410 crossover at 440hz. Maybe I could measure it with my speaker testing application, with a shotgun mic pointed right at the woofer? Anyway, the Marchand fellow likes 24dB/octave, but others have told me that's good for a PA but "too steep for music." Any advice?
