I've got a 4 inch speaker for my guitar amp. I'm thinking of taking it off and adding on a 8 inch speaker. Would this work? Would this do anything? Why or why not? Thanks!
yeah you could do this, you would just half to cut a bigger whole. It would make a difference (most likely) in that a speaker twice as big as your old one would probably have more wattage. I'm not an expert on how a speaker with more wattage changes the volume of the same amp but i know first hand that it does.
If distortion was coming from the speaker, then it well might sound better.
If coming from amp, it boils down to how efficient the new larger speaker is compared to the older smaller model. If more efficient, then it would produce more volume for the same amp setting, and hense distort later in the amp volume cycle.
