I've got a 2x10 speaker cab. 24-1/8"W by 18"H by 9-3/4"D, birch plywood floating-type baffle board, open back, finger joined pine. Basically a Fender Blackface cab clone. If I were to swap in bass speakers, would it work as a good sounding bass cab?
You can make it work well if you carefully chose the drivers that would work with the internal volume of your cab. You would need to seal the back of the cab and adding some kind of internal bracing would be a big plus. Hopefully some of the cab gurus here would be willing to help you further.
You'll likely spend more for the right speakers for the cab's dimensions than what the completed project will be worth. But, its possible to do if you do the math and order the correct drivers.
Thanks for the feedback guys. I'll take your advice and let the guitar cab be just that and get a cab designed for bass.
