At the moment, I have MA R270HD speakers for the fronts and R90HD's for rears in a 5.1 surround system. I want to add more speakers to get spread more sound around the room because TV is in corner of room but we have 2 sofas in an 'L' arrangement for viewing. Would it OK to keep the 2 R270's at the front but also have R270's at the rear and reposition/use 1 or both R90 elsewhere in the room? The AV is a Pioneer VSX-920 (see spec list below).
Thanks
