    Default polk CS2, Polk CS20, or POLK CSI A4

    I currently have the polk CS10, and was wanting to upgrade. I likely should have gotten the CS20 ti begin with. My current speakers are the TSI 500 in the front, OWM 5 on the side, and TSI 300 in the rear. I have the Denon 1911 Receiver.

    I do like the CS20 but like the sound f the CSI A4 Better

    How much of a difference is there between the CS2 and the CS20. I did notice:

    - CS20 has a silk tweeter vs cloth
    - Slightly wider Frequency range for the CS20 (Only 3Hz)
    - the CS20 is 91 DB vs 90 DB for the CS2

    The concern I have with the CSI A4 is that it is 89DB vs 91BD for the CS20. Is the increase in sound worth the decrease in efficiency? Does it even make much of a difference?

    Any help would be greatly appreciated.

    Has anyone tested the difference between the CSIA4 and the CS20?

    How well would the CSIA4 blend wiht the TSI 500's?

    Haven't heard all of the speakers you've listed, but everything I've read says to use the CS20 with the TSi line. I just recently upgraded to a CS20 from a CS10 myself.

    Yes it was worth the upgrade. Dialog has much better definition at lower volume levels.

    UPDATE: I compared the CS20 and the Csi A4 yesterday side by side and I actually liked the CS20 better. The person working there said the same thing. There were not huge differences between the two. The CSI A4 seemed to have slightly brighter highs, but the overall sound quality went to the CS20's.

    I wanted to make surwe he was not just some clown saying what I wanted to hear, and he had the Onkyo 808 and the B&W speakers, neither of which were sold at the store I was at, which to me showed that he took his home theater experience fairly seriously. .

    I had the CS20 for a while with my RTi A7s - great center, but it is not timbre matched w/ the RTi A series. I ended up upgrading to a CSi A6 for that reason mostly. Similarly - if you're using TSi 500s for your fronts, the CS20 should match w/ them.
    ALL BOXED UP for a while until I save up for a new place :(
