which is the higher level product, from what I can tell both are coming in around the same price range. Both are Harman Kardon products, both speakers seem to be pretty much equally good. What I'm thinking for myself.... JBL S-26II ~$166.00 (used as rears) JBL S-CENTERII ~$198.00 (used as center of course ) I have an HK AVR225 Receiver. are these speakers overkill ? underkill ?
