I have a pair of Rti 150s which I purchased in 2003 and a 12" Velodyne powered sub. Would CSi5 center and FXi A6 surrounds be an good timbre matches. Asked Polk technical support and didn't receive response. Polk suggested system matches on website are outdated as Rti 150 is a discontinued speaker. Marantz Sr 8400 7.1 is receiver. Any help greatly appreciated. Thanks
