Additional Speaker Setup Options

[screwuhippie]

I was hoping to get some speaker advice. I just picked up the Onkyo TX-NR1007; I currently have two Infinity Primus 360 Floor Speakers, Infinity Primus PC250 Center, some RCA subwoofer and a pair of Primus P152 Surround Speakers.

My intention is to run Heights and All 4 Surrounds (two rear and two reg). What would be the "best" decision for the 4 additional speakers I should get? And where should my existing P152's go? I think sticking w/the Primus line is the prudent thing but ... should I get bigger surrounds (P162's) or ... smaller (142's for the heights)?

Any help is appreciated. Room is rectangular approx 17 feet by 16 feet ... plan on putting the "listening area" 8 feet from the TV/Entertainment center where the Towers/Center will live. Surround Rears would live on the bookshelf's at the back of the room and the surrounds would be wall mounted on the sides.

Thanks

Paul
