I have recently read online (It must be true!) that "A 10 inch woofer in a 2 cubic foot box will put out deeper bass than an 18 inch woofer in a 2 cubic foot box." This is because the 18 inch woofer is suffocating and choking in a box that is to small. Is this correct and what are the limits? would a JBL GTO 8" in a small box play deeper than a JBL GTO 10" in the same small box? I have been out of audio for a while and I was always under the impression that the bigger the sub; the lower it plays.
