So I'm pretty much stupid when it comes to cabinets.

Could I pair 2 8 ohm Ampeg B series cabinets with a Peavey Firebass 700? Is that okay?

[Downunderwonder]

Sure. Firebass goes down to 2 ohms so any two cabs will work. Best to have two identical cabs though.

[SunwellBass]

I have 2 Ampeg B series cabs, one is a 4x10, the other a 1x15. I feel like it'll be a good setup, it'll at least hold me until I get the Peavey 8x10

People will tell you not to mix speaker sizes, but I say reserve judgement until you hear it yourself.
