REL subwoofer using only red cable not yellow per REL technical dept

Hi,

I am using a pair of REL 5/SHO subwoofers for 2 channel application and find it mates well with my pass monoblocks and harbeth 40.2 speakers.

I called REL recently because only using minimum setting( 10 clicks ) for gain and crossover and whether newer 812 faster sub would allow me use higher crossover and gain. 

REL suggested first unplug yellow wire from speaker terminal and turn up sub gain as that might improve the bass integration ..

So far sounds promising....just wanted to let others know about this possibility although YMMV....

I am under the impression that if you use two REL subs and hook them up to mono blocks...one sub per channel, you should sum the red and yellow wires together and attach the pair to the positive terminal and the black wire would go to the negative terminal...for each sub per mono block. This is how I set up my two REL's with my tube mono blocks.
Not sure if this applies to a balanced design mono block.

Yes daveyf you are correct that is the correct default setup but REL is telling me that if I connect only the red cable I can raise the gain and the sound might overall sound better

Do you REL guys have any idea what you're doing? Or is it all colors right on down the line?

REL also provides assistance with some very informative information on YouTube which might also apply to many other brands of subwoofers. https://rel.net/how-to-connect-my-rel/
