Posted December 7, 200816 yr I really want a 18, extremely bad but I have been lead away from it due to trunk space.My question is, if I put a SSD 18 in a 5.5 cuft box how would it sound compared to a SSD 15 in a 3cuft box.I wouldn't have a problem fitting the 15 in but the 18 would be a snug fit, but its much more appealing.
December 7, 200816 yr id say go with the 15, with an optimum enclosure for it. since you wont have enough space for the recommended enclosure for an 18
December 7, 200816 yr Author 5.5 portednet volume, and with or without port displacment?5.5 after sub and port displacement
December 7, 200816 yr Author sq inches of port?Around 75-80 square inches of port, tuned at 31-32hz13-14 square inches of port per cube.
December 7, 200816 yr i would like to hear some opinions as well, im working with about 7 after port/displacement for an 18" (12^2 inches per foot of port)or optimal for a 15" (16^2 per foot of port)help!!!! i really dont knowww!!!

December 7, 200816 yr It will give you a more peaky response in that small of an enclosure, even if you tune low. If you go ahead with it, definitely add polyfill to the enclosure to help it out.
