Moving up in the REL line of subwoofers

@glenmschneider 

I thought the idea of of 212 series was that it’s like a built in line array

No, that is not correct. In a line array, each level in the stack has a different role and is tuned differently (with independent settings each for xover and gain) . That’s not possible with the 212. They are just big subs with more drivers, but all are tuned together. They only have one set of xover/gain controls.

Anther vote to call 'em. I did and they were very helpful. Refreshingly so.

Moving subs around, AKA pragmatic room coupling, could be it (you will get more magic). But more subs at different crossover points (as I understand it) oh heck yeah to that too. Most folks who got 'em love 'em.

Goggle pragmatic room coupling and it's easy to understand why.

All very interesting information. Thanks so much.

To those of you trying to help the OP get the best sound with what he has, I’m not sure you’re understanding the ‘itis’…. 

Move the subs from front stage to the back wall...or along the sidewalls behind the seat. The 2 subs sitting up front (for your viewing pleasure) didn't do some worthwhile things for your room, perception of deep soundstage, envelopment, etc

Lack of long sub cables would be a reason for subpgraditis
