IMLHO I think the REL is pretty good but ----- not up to good integration with the Dyna's which are very high quality very fast drivers.
Also I am NOT a fan of plate amps. I use a Threshold on my subs, prior to that was MUSE which was excellent but just nat's hair slower than the Threshold but had much more explosive bass. I have my subs matched to big maggies so speed is of the essence, and I think with Dyna's you'll find the same thing.
The Vandersteen subs were very quick for a lower cost mass market sub.
