Oh, and for the subwoofer DIYer, Rythmik offers some of their models as kits. The kit includes a plate amp and driver(s), you build the enclosure (or H-frame for the OB). The cool thing about that is, in the case of the F15HP model, the factory enclosure is 3cu.ft. (to keep shipping costs down). Brian Ding recommends a 4cu.ft. enclosure to produce the F15HP’s maximum possible output.
GR Research provides enclosure plans for his F12G sub, and both H-frame and W-frame plans for the OB sub, all viewable on the company website.
