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....

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/

Please excuse the post from millercarbon, he is incapable of recognizing any other subwoofers beyond his ‘swarm’ sub system. He can’t seems to understand the simple fact that most people don’t have room for 4 subs, no matter how good they sound.

Would anyone know if there’s a hum using a single Pass Labs monoblock
with a single Rel Subwoofer via speakon connection? Rel Acoustics claims you need to connect 2 subs when using monoblocks.

Wow, this is great info.  I just returned a REL based on my experience with one click making too much of a difference.  For instance, 7 clicks wasn’t really audible, 8 clicks was too much.  I figured I had bought too much sub for my little totems.  I recently realized that there is a speaker / recommended sub section on RELS sight.

Yep, they have the "Subwoofer Finder" tool, and suggest what sub(s) to use, but don't mention anything in that tool about using monoblocks, they only ask what type of speakers. Lots of helpful information on that site, and it would be worthwhile reading some of it prior to making a purchase.
I was hoping someone like @karmapolice would be willing to disconnect one of his Rel subs from one of the monoblocks and report back if there is any hum (assuming he still has rel sub and pass labs monos), or anyone else for that matter.
