ok, I decided to build my own subwoofer for music, but I'm unsure of a few things. The first thing being the driver, I'm in search of a good driver (around 500RMS, less if anything) at a good price (under $400). I'll be using a 500RMS BASH amplifier from parts express to drive whatever i get. Searching this forum i see that many people prefer dayton for their subwoofers, any other recommendations?
