high end subwoofer...which one tho?

you can't go wrong with any of those brands

i still say the old velodyne ULD series are some of the best subwoofers ever made. pretty cheap on the used market...if you can find one.

I guess when you say hi end sub do you mean hi end for 3-5k? Or less? Or more? :)

1k? = REL T1 It's increadible... you may not need to look futher? Slam reliablity, fun, easy to set up... and some how intergrates into any system? How? You say? Long answer but worth finding out.

3k ish = REL Brittania B1 (I'd get two of them... rel prefers 3 per room... they come set up for an amazing way to to divide all three)

4k = Thiel SS2 (Use two...) Well yes it's on the audiphile level of sub, but the fact that your loins will shake while ever so gently tickeling your ears like some one put a feather in it isn't so bad either.

I actually really enjoy the Theil SS3 Sub. Although it's no longer made it will almost pick up your house and walk away with it. But for a budget just get 2-3 rels (t series or Brittania Series) and you'll freak anyone who comes to your house and watches U571 (Depth charge scene) to running out of the room and crying like a baby in fear.

I just might do that right now... My neighbors dog keeps barking..

Like a good que butt can be used with both a snooker and straight pool shafts a good sub can be used for both two and multi channel systems. Today it's setup and EQ that intergrates any sub into the room. IMO JL and Velodyne will make this a simple task especially if you don't have room correction, and also provide the ability for truly deep output. This same EQ will allow any size sub to be used even in a small room, not that you need it though. I use a Meuci Power Piston and two Velodyne DD10's.

I like the Revel B15. I run two B15s and they are front firing. In a small room one would be fine. I had a HSU Research big guy, but it was down firing and caused my wood floor to rattle. I do not have that problem with the front firing B15s and the position in the room was the same for both subs.
