I got an old cab for $50, a vintage Fender Bassman with 2x15's..... Ths speakers were generic replacements (non fender) and they were blown anyways...... The problem is the dumbass who had it for me, put in 2 10"'s speakers (pioneer speakers from a car!) they were blown also...... So there is 2 holes for 2 10"'s, but I don't want that, I only want 2 15" speakers....... I am really bad with sawing and measuring and technical stuff, so I was wondering if I can use some plywood to cover up these 2 10" speaker holes...... Not sure if it would affect the sound, it would be covering these holes up, do you think it might rattle? I am thinking of doing this first, and if not have to bite it and get or make a new baffle board Any ideas? thanks!
