I’m a bit stunned here. I bought a Quatro 15” driver and PE 500 watt amp with the plan to build this in the spring. I’m sure you guys knew what would happen better than I did. Anyway, I’m nearly done. Sorry, I have no access to a digital camera to post pictures. I have the cabinet assembled and have put a coat of primer on it. I had a couple of questions left. 1. Is there a real good reason to paint the bottom of a sub? It will be on a carpeted floor in the basement. 2. The driver came with what looks like some type of gasket material. If it for sealing the driver to the baffle, do I remove the paper that it is rolled up in? It’s been fun so far. Even though the lumberyard cut one of the sides about a half inch short, I did not have too much of a problem trimming the other sides despite my inability to cut anything in a straight line, no matter what I do. I just put the end I cut on the bottom. The guy at the lumberyard suggested gorilla glue, which was fun to use. I used some stuff called NU-Foam poly-fil. It came in two pieces that were 17” X 15” x 2”. I split the pieces and cut them from there and glued it to the sides. I managed to not get the sides of the box exactly lined up, but caulk covers a multitude of sins. No gaps were more than 1/16 of an inch. The Precision Port was a pain to assemble, but it finally went together. If you use Gorilla glue to assemble it, do one end at a time and DON’T SET IT WITH THAT PORT FACING DOWN. Fortunately, I had already decided to port the port in the back. I want to thank everybody for their help so far.
