The speakers of Sony's XBR-X900B have come to kick butt and offer no apologies. They provide the sweetest sound we've heard from any TV, and combine with stellar picture quality to deliver the complete package. As long as you like the look of speakers, that is.
Mount it on your bike, ATV, tailgate or wherever you want 450 watts of incredible water- / weather- / party-proof high-performance sound. Features Bluetooth streaming, in-line, multifunction control and more. Was $365.
