Our 18" subwoofer has always been one of our biggest hit items. We sell approximately two of these a day. The folded style cabinet adds that extra thump and gives you the low end you crave. We have received numerous requests for "empty" 18" sub cabinets. Now you can load them with the woofer of your choice. If you are looking for good bass, without breaking your wallet, these are the cabinets for you. We have such a high demand for these, that we have no problem buying them back from you if you do not like them. We rarely get any returns on these, but like all our items, if you do not like it for any reason, we'll buy it back from you.... no questions asked!! Feel free to call us if you have any questions on performance or how to hook them up.Features:
