I think that would definitely be pretty potent, for sure. Just be aware that with that head, you won't be able to pair a 4ohm 2x10 with another cabinet, that head isn't 2ohm stable. If you want to keep the option open for another cab, get the 8ohm... 320watts is still a pretty darn good amount of power for a 500 watt cab. Just throwing that on the wall for you!

I won't be paring any other cabs with it anyways. I really prefer the sound of one cab (be it 10's 12's 15's or whatever) over mix and match cabs. I'll probably get a 810 or 412 in 4ohms for when I become a rock star.
