Which REL sub, R528 or B2

It is a lot more simple. Here at Audiogon it is words. In real the sound does the work. It shows that the words are as it is said. I do a-b comparison all the time. It is not about me. ( then you still don't understand) It is only about looking further!

I use a REL B1 with my Sonus faber Cremona Auditors M and it has no problem keeping up with these very fine monitors. Speed is not the issue; integration is, and nobody does it better than REL. I tried Velodyne and JL in my home on trial and decided that the B1 was the best choice for my setup.

It is about timing and response. This is the most important part for any subwoofer. Paradigm can maybe go low, but this does not say anything about the speed in response. Integration with the speakers is the main thing. This sets a subwoofer to a higher level.

Timing and response as well as "speed" are utterly useless when used in a conversation about subs in any context other than discussing the design of a sound system for 100,000 listeners spread over acres at a festival. Bo's relentless nonesense insults the intelligence of experienced hifi freaks and spellcheck designers, along with displaying a sadly inadequate and misguided sense of musical taste...otherwise it's all good.

B2 all of the way. That was a wonderful REL series.
