Ok, I've got my new TV (50WT29B). It comes with a built-in digital 5.1 system, rear speakers, and a left/right/woofer in the TV. I want to get some front speakers and let the TV act as a dedicated center. The TV says in regards to the built-in amp: "48W RMS (68W RMS with external front speakers)". So what on earth does this mean in terms of what I need to buy? Do I need to look for 2x10W speakers, or what? Also, any recommendations < about £100? Thanks! A confused newbie who couldn't find any info.
