I have the 10" partsexpress (that is "parts express" not "part sex press") Dayton subwoofer. I don't recall the price I paid, but it was less than is currently advertised on their site.
It works very well for my needs, but the only thing I have to compare it too was a crappy passive from an old HTIB. I am going to NOT audition any other subs as I get upgraditis waaaaaaay to easily.
