Looking at your floor plan, the qs8's behind you should work fine.

I'd also think about the VP150.

Lastly the sub. I own and love my Hsu VTF-2, but at the same time, I'd like to get something bigger, and beefier some time. You may get that itch too. If you can afford it, scratch the itch now. Look into the VTF-3 from Hsu or even the EP500 from Axiom.

Enjoy your new setup!
