The SB-100 was a passive sub sold by Paradigm long ago.
I found this picture online a while back. The wiring diagram on mine can no longer be read.
I walk past it every day and wish I could put it to use again.
In the last two days I've watched a few good movies without my subs. The M80's really do sound nice on their own.
I am tempted to run the M80's through the SB100 just to see.
I'd think its pretty unlikely I'll put more than 100 watts through the sub to the M80's.
Not sure how the ADA would handle the impedance though.
