Hi Art,
Did you end up using your Sansui speakers? My living room system has klipsch la scalas, so this kind of bass roll-off isn't unfamiliar, and to be honest I listen to mostly older recordings on LP, so not a big problem. The la scalas however are well designed, and don't have any gross peaks or valleys in the response to color the sound.
still have yet to measure the second woofer, am curious to see if maybe they have deteriorate over time
Best regards
Max

Yes, I used one pair of mids and tweeters for my kitchen speakers, using a separate sub woofer, the other pair of mids went into patio speakers, and the woofers were given away to another vendor at the Albuquerque Flea Market before I moved down into the path of Hurricane Matthew.
Power just came back on after a 27 hour outage, considering the amount of trees taking down power lines all over, I was quite surprised to get power back today.

Wow, that's a lot to endure! Hope everything ends up okay!
It's cool you re-used some parts from the Sansui speakers. I've been drawing out a schematic for the crossover, it's a bit of a mess. There's switches to bypass it in order to use three separate amps and an active crossover (which makes little sense to me considering this isn't that good of a speaker)The mid and treble level controls used tapped auto transformers, which double as inductors for the high pass filters. It is a full three way second order crossover though. Next I will measure all the chokes and driver impedance at crossover frequency and simulate it to see if anything weird is going on like with the bass alignment.
