What can I say?? Im 100% completely impressed and blown away by Soundqubed products.. This HDC3.115 is actually too much of a sub for me. Im pushing it with a 2600w rms Hifonics Brutis BXi2610D amp and its all I can do to stay in the damn thing. I bought my sub, box, and amp used. I have $220 in my sub and box and $125 in my amp. The quality of the workmanship and build of the HDC3.115 Subwoofer is very impressive. I definitely recommend it to everyone who is interested in a good cheaper spl sub.. For $299 new shipped free it gets my vote. Although I think im ready to step down to a single HDS310...im getting to old for this ish.. Lol
