I think it has more potential than a 3500 series. The 3500s I used didn't like much over 2k daily whereas I think the HDC would walk away after that. The 3500s and 2500a are probably more efficient at lower power levels though so that should factor in. The HDCs also dropped a lot lower on a straight swap for me.ive heard the hd3 is about equal to the 3500 series?
what box? what car and amps? the 3500 is alot more efficient in a daily application, its not intended to fart boxes but can be used... in SQ the 3500 all the way for SPL the HD3 will do a bit better... its 2 totally different woofers.. and BTW the power handling on the 35 and 9500 are much difference... i know people that put 2500 to there 3500s with no problem..I think it has more potential than a 3500 series.

x2wrong
The DD 2512 will work fine as long as its clean power I know of several dual 2's being run on DD M3's at .5 daily......so around 4000 rms for the pairwhich one? Off of 2k rms.
