I have a RTi set up the old rti55 csi245 rti35. So here is the question im thinking of upgrading the whole system to LSI25, LsiC and LsiFx. I use the system for movies and tv with about 75-80% of them time. Is this the right setup? Also the LsiFx will be mounted off set by about 3 to 3 1/2 ft. Also i need to find a reciver that has hdmi 1080I atleast. What size of amp should i be looking at?
