I am moving up to DTS and purchased an Onkyo SR500 as a starter unit. I have Klipsch 2.2 front speakers with a matching 2.2V center channel. They have (2) 6 1/2" woofers and a horn tweeter in them. Anyone have any experience with these speakers and if so, what would you match them up with for surrounds? I am not in the loop as far as HT goes, so any advice would be appreciated. Thanks.
