Axiom Home Page Forums General Discussion Technical Questions Crossover Question With Crappy Sub

I have M-22s and an Onkyo receiver paired with the original subwoofer that came with the Onkyo HTIB 6.1 set-up. The sub does a lot of muddy bass rumbling but doesn't do punch at all. So my question is about the science of where to set the crossover point. I can choose 60, 80, 100, 120, or 150.

I'm thinking if the sub sucks, that I want to let it do as little as possible, so does that mean the crossover should be set lower at 60? And does that mean, ideally, that the M22's will do the work down to 60 and then the sub takes over?

And if I wanted the sub to do more work and take over more frequencies I would raise the crossover point?

I know it may not be this simple and I can't really tell too much difference in the sound but would like to know why I'm doing what I'm doin'.

Thanks
