Has anyone tried the new KL-6502-THX / KL-6504-THX Speakers from Klipsch?

I'm wondering how they compare with the KL-7800-THX speakers.

I currently have a full set of the KL-7800-THX / KS-7800-THX and would like something a little better for a center channel so i was thinking of swapping it out with the KL-6504-THX and was wondering if i would see better performance from it vs the KS-7800.

Thanks for your feedback.

Been looking at the THX in walls for a while. What do you feel is lacking in your current kl-7800 center channel?

Also, I don't think the 6502/6504 have an integrated enclosure so seems like bass response may suffer.

Just a little clairity, it may just be my room as i havent done any acoustic treatment yet. Don't get me wrong i'm not trying to talk down the Klipsch THX inwalls, they are awesome speakers and i love the sound and look and would do it again in a heartbeat.
