Speaker cross over frequencies?

[Automission]

Okay, thanks for the tips, will take it from here. The center seems fine, it's just the rest I can't sort. I tried the sub turned up to 120hz, but it was so ****ing loud, it over powered everything. Regardless of volume levels, so I think I might leave it at 90/100 as it doesn't take too much and just gives a nice rumble.

Still not sure on the towers and surrounds. I do like the idea of setting them lower and getting a wider sound range, only I worry the more low end sound will overpower the high end. And like I said, if I send it to the sub, that just over powers them all!
