How many can you get in an 18x13 room. I think I read somewhere but don't remember at what point do you need more than 1 amp per channel for the subs?
I've run two triple towers in a room that size although I'm currently running duals. Both work bery well..
You can u up to 3 of the SW 12 16FR's on a single amp so for quads or 6 stacks, you need to use either an HX 800 or 2 of the A370 amps per tower...... if you use the SW12 08FR's, you can only use 2 per amp. I always recommend folks go with the 16's even if doing duals, it leaves an upgrade path.
And again, note, these cabs are no longer featured on the GR Research site, if you want our beefed up version or our modular version ( all shown in this thread), you need to deal with us directly. Have had a number of folks confused by this thinking they were getting these cabs when ordering off the site
