REL does indeed recommend two(2) subs if you are using mono block amps. I have mono blocks, so two subs it is. However, the issue becomes that depending on room size, two subs can easily overload your room. In my case, my room is very small, albeit with a vault ceiling ( which adds to volume), so the little T5i is the maximum that I can get away with in this room. I think one has to consider the room/sub interface as a major factor when using two REL's. If you utilize mono blocks and your room is like mine (11x10) or smaller...and without the vault ceiling, I would suspect that you will run into trouble with the various room nodes you are going to excite.
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....
