Which REL sub, R528 or B2


I'm planning to buy a REL subwoofer. It will be used in audio system mainly, but also in HT from time to time. I listen to jazz, vocals, occasionally rock. It will support Dynaudio C1. I'm considering the new R528 or B2 ( can get them at roughly the same price).
The new 528 looks better but is it as good as B2?

Bol972 continues to describe "speed" and "timing" as if they were actual things that matter. The voice coil of a paper, aluminum, graphite, balsa wood (!), ceramic or macrame reinforced dried Yak turd driver all get their signals at something like the speed of light, and the tone and output sound dissimilar among brands for reasons having zero to do with what he (and others) describe as "speed." Using your EARS to decide what bass tone sounds best in a particular room is the ONLY way to find what you like, and this is as true now as it was 10 years ago. Just typing that seems ludicrous but I do what I can. I find the weirdly sincere condescension from Bol972 annoying, but it gives me something to respond to not unlike having to deal with a loose monkey jumping around my hut.
Mister Wolf is here again. What we do in this business is comparing all the time. With subwoofers the same. Wenn a subwoofer has more control and authority it is easyo to hear. The same wenn you do a test to find out if the instruments and voices still have there dimensions. And the level in which they dissapear. Every person wants to have the best quality for the money they spend. Maybe there are fools who like to get less!!
