      Quad 8 enclosure

      Posted by Matthew on Sep 11th 2022

      I'm beyond happy, I've talked to box builders and a electrical engineer. I took a chance and it was worth it for my ears. We hear what everyone else is doing, it's always the same thing, never completely satisfied. I'm happy with my purchases, DC Audio m3 8 dvc 2 @ .7 ohms on a Wolfram W-3k, stock alt, Northstar batt, 2753 watts final. Gladen RS-150c2 pushing 3 way a-pillars and the top of of the door another Pod with CDT Audio. Mosconi as200.2 just for the lower part of the doors. No Rear fill.
