Well I decided to build the hx2 again. I'm just going to keep the motor and do a 12" 6 spoke frame, 1800rms 4" dual 2 ohm coil, 9.25" 3 layer nomex progressive spider and a big roll cone. Should be a nice sub, the HX motor is 300 oz so there is plenty of horse powers there. Will post pics, waiting on parts from Lord of Bass. Pics of the 10 I built while we wait lol.
