>>A Vandersteen is faster as it High Passes, cleans up the hump, unloads the main amp...the Rels do not Hi pass...<<
Not fast enough for me. I still hear the dynamic disparity. Yeah, a Vandersteen is a pretty good sub for all the other slow speakers out there, but not for this one. I didn't mention Vandersteen because I don't believe the V sub is up to the challenge.
>>You really need to try a pair set up properly high passed before offering advice.<<
Been there, done that. Not impressed with the result. The Zu sub is as quick as a sub gets, and still I'd run LS3/5a without, double them instead. Far more natural and integrated.
