Axiom Home Page Forums General Discussion Technical Questions Glue Type Used on Woofer Assembly?

AFAIK the woofer has always been directly driven on M3/M40... and at first glance that still may be true. The crossover on the right (assuming that's from your M3 ?) only seems to have one additional capacitor, so it's likely that the woofer is still directly driven. Might be worth tracing out the circuit, probably just a one layer PCB...

Definitely if the cabinet doesn't seal that is going to mess up your bass pretty seriously.

If you lived a bit closer I could drive over with my M40s and try some mixing & matching, but Richmond is a fair haul even without the hassle of going through customs.
