Budget Subwoofer?


I'm looking to add a subwoofer to a small system (NAD C715 receiver/cd player with a pair of EPOS ELS-3s). Someone had recommended av123.com a while ago, but they no longer sell a budget woofer. By budget I mean under $300 USD.

Thanks for any advice you'all have!

Did not get your room size or what will you be mostly used it for, music or movies. Anyways, for up to $300 you could eBay for a good used one such: Velodyn VRP-1000 or 1200, DER-10R, DLS-3750R, DPS-10, and some of the Klipsch's.
Thanks for the pointers and help. It's a 19 x 11 room and it's for a stereo, not a home theater system. We listen to mostly rock of various sorts, R & B, some jazz, and a lot of acoustic music.

For $300 or less, if I were you, I'd keep it 10" or below.

* Do you have any good samples on instruments/acoustic that I could look it up on YouTube.com?... I like something that could put me into sleep.
