Which REL sub, R528 or B2

I just made a new REL cable from some Canare "star quad" stuff originally for no reason other than the Canare looks better (black mesh covered). Surprise surprise...I thought my old simple cable (some generic 4 conductor OFC my local audio joint gave me) was fine but this is better. Much better. Weird but true...higher sensitivity and definition for about 30 bucks (I, of course, used the same angled Speakon with good spades on the amp side). Oh yeah...and it looks really cool.

I have my REL sub. Seamless integration with the system, perfect. Bo1972, you made a great suggestion to use a calibration system (in my case Yamaha Ypao, yours audyssey)for setup... I have balanced speaker volume and the sub... sub's volume is only 5 clicks up.. I set it a little bit to high by hearing. Crossover 34Hz is fine.
Soundstage has improved, more palable or more "touchable" as Bo1972 says, kind of energized and obviously better bass, deep with great control. It was a good investment, great upgrade.

I don't get calibration systems except for the "gear adjustment challenged" listeners. I may have some advantage as a long time musician and concert sound tech (although among audio geeks that seems doubtful), but I trust my ears and other than my REL adjustment knobs I don't have any EQ on my preamp anyway (other than bass level tweaking I don't need any). Recordings have an infinite range of mixing results and sometimes the bass is way too loud, thus requiring my only EQ move which is to turn the sub down a little from time to time. Does anybody else do that? If not, why not? Do you surrender the control to a calibration system? Are we not men?

Wolf garcia, apparently you don't have idea what you are talking about. you are the man. that's for sure.

Jkuc...please explain...no wait...please don't explain as I somehow doubt I'd understand...really...thanks.
