Havent bought yet but looking to get Vizo 47 lcd 1080p, onkyo txsr 605 receiver. Lg dvd up convert player. Front center channel nxg technology, NX-PRO5520CLR, front left and right nxg technology NX-PRO6220, Polk psw 10, 50 watt subwoofer. Haven t decided on back speakers and haven't bought anything yet. I have a trey running across top of fireplace and LCD will go right above fireplace and there will be about a 1 ft gap to center channel. The NXG center has pivoting tweeters, any thoughts on system.
