Which REL sub, R528 or B2

I currently use a REL T5. It can keep up with my Sonus Faber Guarneri
Hommage's! IMHO, any sub that can keep up with these speakers is anything
BUT slow!!
The set-up of a sub- and REL is no exception, is crucial in this regard, wrong
set-up and the results will be a mis-match with the sat's....leading to the
impression of a "slow" sub. Subs are NOT 'plug and play', particularly
when you are trying to get the blend with a quick mini to be seamless. IMHO.

Bo1972, Wenn (????) you are a dealer and a competing product is superior, it can be very tempting to denigrate the competition.
Unfortunately, wenn (????) your customer discovers the facts, this can lead to a less than stellar reputation...just a thought.

Wolf, I think that the REL sub has enough flexibility of control to blend seamlessly with any main speaker. I know with my SF GH's that they blend seamlessly with these speakers. The GH's are ultra fast, and even though i was concerned that this would be an issue with the sub, that has turned out not to be the case. OTOH, it did take a lot of adjustment and fine tuning to get the correct blend, BUT I did it by ear; I suspect if I can do that most anyone can. Plus, the hook-up of the REL directly to the amp is a MAJOR benefit as far as I am concerned.

Wolf, I now see what you are saying. But it doesn't make any sense to me. The x-over and the level should be right for all of your recording's. If you are increasing the level from recording to recording, something is wrong, IMO. Again, IMHO, if the level and x-over is seamless with the mains, then the amount of bass will be reproduced as per what is appropriate for the recording. If you like a louder or more forceful bass response, then increasing that control is simply overloading the bass and probably the room for other recordings. Sounds like maybe you need an equalizer in your system or some such thing. Why are you using your Sub's control's as an equalizer??
