FYI, aside from having the room, the reason I am looking at this for an upgrade is that my version of the EP500 pretty much cuts out at anything below 20Hz. While that's still very low, and I have plenty of output at that level, I'd still like to start plumbing all the way down to 10Hz or so, maybe just because it's possible! So, I'd be thinking of the 800 just to hit that 10-20Hz range that i am currently 'missing'. Maybe it's good ol upgradeitis setting in. Since I can't upgrade my mains and I already have 7.1 and don't have room for height or wide channels, the sub is all I have left!
