Best musical sub for a Triangle Celius?


Room is 25 by 35 with 10 foot ceilings. Used only for stereo. Powered by a unico hybrid int. am. (Rules out Vandersteens.)

Initial thinking: Paradigm, REL, ACI, and M-Logan.

Thoughts or experiences?

Thanks all. I have some work and research to do. Anyone ever heard or heard of TBI Magellan? Very unusual design but am told that it's very very fast and "musical," although not a HT volume generator.
I don't know if I have a good set up or not. I have a HGS-12 and a HSU 10 inch with my Celius. The Velodyne always seems a little heavy and a bit slow. I like the Hsu, it's a light weight driver and seems a better match but doesn't go as low. I think I'd be happy with just the Hsu even though it's a very inexpensive unit. I just like the tone of it.
Thanx, Russ
I did a lot of listening. REL B series, M-L, Totem, B&W, etc.

Guess what blew everything away?

Paradigm Sub 12. The auto set up feature is a Godsend.

I was shocked. Not even close.
