I have Polk LSI15 fronts, LSIC center, RTI100 as surrounds , a CSI 30 for back and an LFM sub. The Polks sound very good with the Outlaw. I used to have A Sonus Faber Solo for center channel but it just sounded too harsh with the 950 and it did not mesh perfectly with the LSIs-So I just put it on EBAY.Speaker selection can make a huge difference. From what I have read on this forum, everyone who has Polks seems to be really pleased with their pairing with the Outlaws.
