Does exactly wht it claims, same exact thing as a DD, which is a very good and expensive brand but this one is less than half their price. It sounds very deep, amazing, cery loud with the right amp, cheap ones will make its limit alot less than it could be. If you have never owned a sub or a very loud one i would recommend just getting one of these and do it all right or take it somewhere it will be done right and your ears will ring. Makes my windows flew( not at full power) break it in right and upgrade and door speakers that are not atleast 50 watt rms, or add tweeters. Looks a hell of alot sexier in person, huge as hell. If you are looking for subs to break windows this is not it thoue, it will moke them for sure but not break them, 2 would, ir the hdc levels probably. Box built 4.5 cubic ft, tuned 33-35 herts. You will not find another sub this amazing for the price, as loud if not louder than any memphis mojo or crossfire ive heard. Subs this loud and good are priced atleast $1000 so take this deal guys, everyones been impressed with my single 15' and im sure your neighbors will know who you are after jamming this one around, turns heads, and dynomat is a good idea unless you want your trunk to rattle like a snake. BUY THESE SUBS GUYS, dont go anywhere else or believe anyone saying to do otherwise. These are awesome. Thanks!(:
