Hi all,

I am a newbie, I just bought a Yamaha RXV-2500 receiver with POLK RTi4 and POLK CSI3 center,Velodyne DLS-R 3750 SUB and R15 surrond speakers.

After reading so many reviews on AXIOM, I just wanted to know the difference pros and cons between POLK RTI and M22TI and as well surrond speakers.
