Okay, done some research and need some opinions. As I stated in a previous post, I want a MUSICAL sub that will blend well with my Rti10s. While I'm sure there are many other nice subs out there, if I don't keep the options reasonable I will never get one. Having said that, if there is a specific model you think I should consider feel free to tell me. So I've narrowed it down to the following three or four:

1) REL T2 ($799) - seems to be very musical and is unique in the way it connects to the amp.
2) Velodyne SPL 1000R/1200R ($799/$899)
3) Definitive Tech Supercube II (approx $850, maybe a little less)

Any help is much appreciated.
