DIY Subwoofer Page

This page is dedicated to the development of my DIY subwoofer.

My subwoofer is a 6th order bandpass box for three JL Audio 8W6 dual voice coil subs. I simulated sealed, ported and 4th order bandpass boxes as well, but none of them would have given me the response that this box did. If you've never built a box before I'd suggest something simpler. I've build dozens of boxes before including one other 6th order bandpass for a pair of MTX 12's so it wasn't a big deal. The MTX box however was for a car audio system and was your stereotypical bandpass "one note" box. It was designed to be loud as hell for bass heavy rock and rap, but it rolled off very quickly. I designed my box to have a flatter response. As you can see there is a peak at 70 Hz but I'll deal with that, I was more concerned with getting low extension so movies would sound good.
