A few years back, I built a sealed sub using an Adire Audio 15" Tempest and a Parts Express 500W BASH plate amp. The Tempest used to be one of the flag ship long excursion drivers available, but Adire has gone out of business. I imagine there are better options to be had now.

This sub plays very cleanly down to about 28Hz at any volume I can throw at it. I bought an EP350 figuring it would match better with my M60s, but quickly came back to my homemade sub. Anyone want to buy a 350?
