Question on surrounds for my secondary setup in my living room. This room is 17x13 and has an open space (pictured below) behind the seating area. This room will be almost entirely TV/sports/Movie oriented as I have a dedicated setup for music. I will be getting the Onkyo 818 for this room (XT32). I have always been a direct fire guy due to priority for MC music. With this setup however, I am heavily considering bi-pole or omnipole for surrounds. Would love some suggestions. The Mirage OM5 sounded like a good option, but is no longer available. Any help would be greatly appreciated!
