Nice Upgrade!!
Hey, I bet you had your original center speaker off-set to the left so that you don't block the IR sensor on the tv, right?
Pretty stupid design! My bro got one from Costco, and his is off-set to the right. I've let a Samsung rep know, and asked him to pass the recommendation along to avoid this in the future!
psst, where are the subs? new ones coming? edit, oh, those aren't subs, hehe, oops lol
