Possible REL upgrade?


I'm considering a subwoofer upgrade...

Currently running (2) REL S/3 SHO subs paired with Joseph Audio Pulsar 2 Graphene speakers...

To the point; I've noticed a handful of REL S/812s available new, new in box (discounted) and used...Is the move from the S/3 SHO to S812 a lateral? Ideas?

I have a 12'x18' room.

Pretty sure going from 400 W to 800 W and going from a 10 inch to a 12 inch Is going to be an upgrade. My only concern would be are they too much for the room? I guess that’s why they invented the volume knob. 

Definitely an upgrade, and maybe some good prices now that the new models have been introduced...

Ok, let's change it up. Thoughts about going to (1) Special Carbon sub vs (2) 812s? Too pricey to go with a pair...
