I'm currently running a 3.1 setup and want to move to 5.1, and while I know I need to upgrade my fronts and sub, my next purchase is going to be surrounds. I'm hopeful someone can provide advice as to the type of surrounds, the location of the surrounds, and specific speaker recommendations (budget up to $400, though I'd prefer to spend less.)
My room dimensions are 20 x 13 x 8 (though there is no rear wall as it opens to the kitchen.) Because of the configuration of the room, I've always assumed bi-polar side wall-mounted surrounds (high on the side walls just behind the sofa) are best for my situation, but I'm really not sure.
I've attached a few photos of the room.
Thanks in advance,
ERICXV
