Rel T1/T2 ??

I would go with the T1. If you can swing It Go with the R328 much better sub.

I would use an S series; the T series was designed for HT primarily. I have 3 S series subs myself.

Don't agree with Stanwal, the T series can be very good for audio. I am currently using a T5 in my system and it's a champ, seamlessly integrating and providing a very impressive foundation. In a very small room, like the one I use, the T5 or a similar size sub is possibly the only way to go, IMHO.
