ok, yes i have built my front 82's into the wall, i did know they were rear ported but it was more a space requirement from my wife, i also built my rw-12d into the wall facing straight on which is a front firing sub, so i decided that i would get suffcient bass that route. It does sound good either HT or music. My center is in the wall as well, still working on it, but i can post some pictures later tonight or in the morning. The reason i asked about the amp is my local klipsch dealer has a setup using the ka-100 with two JL W15's, as well as the 120's, personally i thought the 15's sounded better. But was not really sure how it would stand up over time.
thanks for the replies, much appreaciated
