I am looking for a nice slot port design for a pair of hdc310's running off an autotek 2000.1 at about 1900rms. I have them now in a dual chamber ported box, each seeing 1.5 @ 35. I would like a common chamber box but more tailored to the subs. So if anyone has experience with these subs and can chime in on size and maybe freq would help a lot. I have max measurements of 35w x 22d x 15.75h. Any takers? This is a daily setup and mostly listen to hip hop, with some rock thrown in there from time to time.
