At some point in my amp's life someone has run a bass through it. If I set my EQ really bassy for whatever reason, all I get is a sound that resembles a wet fart. It's the same if I lower the octave down by 1 or 2, or if I have it set neutral but tune to drop D or lower.

The speaker is a Celestion seventy 80, 12" 80w I believe.

Any suggestions for an upgrade? Would the problem even be caused by the speaker?

You could always buy a speaker and try it out and if you don't like it or if the problem persists then you can just return it.
I would recommend trying a Celestion V60.
It's what is in the ENGL standard cabs.
Great for metal.
Better than the V30's

Bad tubes or improperly biased tubes can cause farting noises as well. Check those before swapping speakers.

Replaced some tubes yesterday.
