hello all and welcome to my third installment of inane questions. Can you replace speakers with any other speaker of the same size in a cabinet? say i have a speaker cab with brand "A" speakers. can i take that one out and put in a brand "B" or "C" speaker? now, my logic tells me yes, but i need verification. I read a EarCandy cab thread, and i have read a few DIY threads and websites (which as thor points out, maybe be wrong) and they speak of cabs being specially designed for the speaker inside, and something about resonent frequencies, and the like. Specifically this ear candy thread, where petebass said "People, be wary of any company that thinks it's ok to make one standard cab and throw any speaker that fits in there." now granted he is refering to making one box size and throwing in 10s, 12s, or 15s in one box, but i just want to make sure that if its a 15" speaker cabinet, any 15" speaker will do. Thanks for helping me!
