Shopping for a powered Sub <$600...suggestions?

I'm considering the purchase of a new powered subwoofer (for HT, games, and music). So, I saw the Velodyne DPS-10 today and liked the controls on the front. I'm also considering the DPS-12, but not sure if it would be worth the extra ~$100. Can anyone suggest a good performing powered sub under $600 with easily accessible controls or recommend either the DPS-10 or DPS-12?
Thanks,
Adam

im sure if you do a search, youll find more than enough on subwoofers.

might i also suggest hsu (www.hsuresearch.com) or svs (www.svssubwoofers.com)

as well as many other great subs in that price range

Here's a good one under 600.

For $600, I wouldn't look at much else.

But why would you need controls on a subwoofer? You shoud never have to touch it.
