Rel subwoofers

I have a Storm III, the next model up from the Strata III. When I listened at the dealer to both there was a little difference in extension and quickness. I would imagine that in a small room you might not hear as much of a difference as in a large room, but it will also depend on your power amp and its bass response. I don't think my Storm III is ported, but if it is, I have never heard port noises coming from it. I am not sure about the more expensive Stentor and Stadium models.

Yes, they are much better, go deeper and with more definition and control.

Agree with CMK. They do sound better!
