Axiom Home Page Forums General Discussion Advice from Axiom Owners Comparing the 350 to the 500...

>>This Denon also has another interestins setting in that you can run both the mains and the sub at the same time- I might just try that as well.

If you can only set a single crossover frequency I would stay with 80 Hz other than for experimentation -- if you cross over the center and surrounds at 60 you are going to get a bit of a "hole" between the center/surrounds and the sub.

The "run them both at the same time" setting sounds like your best bet... also see if you can route the LF from the center and surrounds to your mains AND sub. It may just be Yamaha receivers which have that option...

If you can route all your LF to mains and sub, then you can start to play with the crossover on the sub as well, setting it in the 40 Hz range. That way the M80s carry all the bass down to where they roll off (a bit below 40 Hz) and the sub starts to work below 40.
