Subwoofer recommendations for mostly music


I don't know anything about subwoofers, so be kind to me! I currently have some sort of Velodyne hooked up to my system. It doesn't seem to add a thing to my system - possibly because it's crap, or possibly because I don't have it set up correctly! I would like to get another subwoofer anyway, so would like some recommendations. It will be part of my HT system, but I really want one that is good for music. I listen to classical, classical rock, jazz and World Music for the most part.

I will be pairing it with bi-wired B&W CM4 speakers (center is a B&W CMC) and I use a Rotel RSX1055 receiver. (I know a lot of people here don't like B&W speakers or Rotel components, but please don't suggest that I upgrade this stuff first - I can't afford to and don't want to!)

Budget wise, I would prefer <$500, if possible - used is fine.

Interesting thread. I've never seen so many recommendations for Velodyne subs on a'gon! I own a Velodyne myself and have been quite happy with it, but I haven't shopped subs, so maybe I just don't know what I'm missing.

I have two follow-ups that may also help the original poster:
1.) ported or sealed for 2-channel audio?
2.) what size driver is ideal for 2-channel audio?

I recently subscribed to Richard Hardesty's "Audio Perfectionist Journal." Hardesy argues ported subs are fine for HT but NEVER acceptable for hi-fi music. I found this very interesting, since Hsu Research, a highly-regarded subwoofer researcher/manufacturer, claims its 1220HO (ported) subs are better for music than their sealed models. Most of the sub threads I've seen recommend the 1220HO's for hi-end two-channel audio. I understand why they (the 1220HO's) aren't as recommended on this thread, given the parameters the original poster gave.

However, the conflicting thoughts of Hsu and Hardesty intrigue me, and I wonder how many a'goners have found ported subs adequate or superior choices to sealed.

Also, I believe there's a general principle that the larger the driver the less tight the sound, so is a 10" sub the ideal solution for 2-channel audio, or do you need the extra expense of a 12" with even better quality and engineering (to be as tight as a good 10")?

Thanks!
"Hsu Research, a highly-regarded subwoofer researcher/manufacturer, claims its 1220HO (ported) subs are better for music than their sealed models."

Hsu has no sealed models. Their tubes and boxes are all ported.
I obviously don't have the experience to answer this, Aggielaw. All I can say is that my new, sealed, 10" sub is great for 2-channel music. It probably won't be perfect for HT, but I think it will be O.K.. I suppose if I find it unsatisfactory, I can add another HT-only sub to my system, but this one is a keeper for music!
Newbie,

Right you are - I didn't realize the internally-powered boxes were ported, but looking at the website, they are!

Hsu was a bad example. Rather than hijack this thread with a protracted digression, I'll look for a thread on best subs for 2-channel above $500.

Thanks for keeping me straight, Newbie! :)
I own the REL Strata III which I had also reviewed here at A'gon. During my research while shopping for the sub here at A'gon, AA and other places I came across following comments on many occasions

1)Sealead subs are easy to integrate on both counts room as well as main speakers
2)Sealed subs are faster
3)Rel subs are by far the most musical

With the information I gathered it was a no brainer going for the REL Strata III.
