hey im trying to decide what kinda box i should build. I've got a 15" solo-baric l7, and my max dimensions are 28"l x 26"w x 16"h, now that gives me just around 5.5 cu internally without port or sub, so i was thinking of just doing a basic slot port tuned to 32, do you guys think that will be good enough, should be about 4.5 cu after port and sub? thanks for the help
