I'll coattail on this post, Hammer your room will be amazing when it's done - having all that concrete on at least a couple of sides will allow some guilt free volume! Very nice!
The question I have is we are going to put an addition on this summer and I will be building a room in the basement as well. The dimensions will be 23' x 24' (minus wall build, etc.), so in the interest of complete overkill which is something some of us share when it comes to this topic, has anyone split their signal and run multiple side channels and rear channels with any success? For example, I currently have 5.1 and will hopefully immediately go to 7.2 while wiring for 9.2, I have two RS-62ii's and was thinking of adding an additional pair along the side wall and maybe doing a pair (or four (?)) of RB-81's along the back wall.
Any feedback on that? I know the system will fill the room as is no problem, but adding another amp and more surrounds might really deepen things further, or would it amount to overkill and not be that much bang for the buck.
Hammer, with apologies it is not my intent to hijack your post. []
