Yamaha's YSP-5100 and YSP-4100 soundbars (or Digital Sound Projectors, as the sophisticates would say) emerged early last month over in Japan, but then CES happened. In a stellar effort to jog our memories, the company has just announced that both units will be on sale here in the States prior to January's end, and while each comes with a laundry list of features, the MSRPs are downright shocking. Both bars offer up 40 beam drivers, two woofers and a dedicated amplifier, while the 5100 adds a pair of tweeters.
