I’ve been searching all over for a subwoofer enclosure and finally decided to build my own. Without getting into too much detail, I wanted to throw this out there and get some feedback. I’m currently looking into a molding company to make them for production. My thoughts are to have them available as a box only or as a complete box, woofer, and built in amp that can be installed in both amplified and non-amplified factory systems. The one I made holds a 12” woofer, however, it will probably be a 10” instead. The 12 is a little to large for the enclosure and honestly think the 10” sounded better. Current price point for the enclosure alone, sprayed with bedliner, with a pre-cut hole for a 10” round woofer would be around $200. I appreciate any feedback you would have and especially what you would do to enhance it, if anything.
