I have a Peavey Microbass. I love it, great tone, but the speaker for sure is blown. It full on distorts at half volume(not just a little bit. Figure a gain knob on a distortion pedal turned all the way up). It is aslo probably the original speaker, and about ten+ yrs old. I'm just wondering what a good brand is( I know emenence is good, then thats just about it). How much would it be....can I do it myself.... my dad can soulder. It's an 8" speaker.
