Which REL sub, R528 or B2

Yes, I used the original but after I installed the Synergistic Research
cables and I noticed a lot of definition and separation of instruments.
Especially in the bass department. This sub is fast enough to keep up with
my Focal speakers and disappears and is unlocated. The bass is perfect
low and loud in my room. Only one was needed in my corner to supply all
the bass my room needs. I also tried Audioquest and some others but they
were not the best. Synergistic Reseaech Rel Spec Reference Cable does
it all.

Thanks for the reply. I will say the cable did the same for me. I would have to say the cable added to the speed of my B3 because again I heard attack and decay I never knew existed. It blends in perfectly with my Dyn C1 sig's.

Bo1972, I take it your sub is not in a corner placement while crossing very hot?

I'm upgrading my Synergistic Research Tesla SE REL SPEC Reference Subwoofer cable to the new Synergistic Research Element CTS Rel Spec Reference Subwoofer cable in the next few weeks and I will have a full review here.

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.
