Recommend me some good subs around $600.

Kex, drseid,

I should not forget to add that my testing was done some time ago using what was then pretty much the best that SVS had to offer. I've been an SVS evangelical ever since and that does cloud my better judgement. Since it is now in my HT room, it has become the family sub, rather than my 2-channel music listening sub...

As much as I enjoy the SVS, I am also realizing that my esthetic tastes are changing and I am actually looking to replace this sub because of its size to one of the box subs from SVS or any of their competitors. I'm curious to know how the sealed box subs from SVS compare to the likes of ACI, Rel, Dayton (and Rocket?) on music.

Yes, it's for the "family HT" room, but that is also the only place that I can enjoy SACD in surround.
