I am selling the box that the premier 3004 sub I have for sale is in. I would like to sell the box with the sub but will also consider them seperate. The box is 2.8 cubes, ported, tuned to 35 hz, has a double baffle front, 45 degree interior angles, covered in dark gray , the inside of the port is painted black, was built by a member on here. I am asking $100 plus shipping or if you would like the sub and box we can make a deal and if you would like the box, sub, and mtx 81000d amp i have we can make an even better deal.
