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!

The Mirage Omni S8 and S10 are excellent subwoofers at the price. They're no longer made but seem to be pretty easy to locate online. I replaced an HSU VTF-2 with a Mirage S8 when I moved into a much smaller place and found it was easier to integrate and sounded better than the HSU in that space.
Velodyne VRP 1000 or 1200. Paradigm PDR 10. PSB 500i. These are all good budget subs and can be found under
$ 300.00 used. Want a new one?. Go to partsexpress.com and you can get a great value 10 inch subwoofer delivered.
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.
