Yamaha is about to bring a lower cost Sound projector to the market.

The new Yamaha YSP-800 is already coming this month for 699 Euros in Europe. This exciting Yamaha product is able to digitally simulate 5.1 surround sound with a single box. The box itself contains 21 speakers that simulate a 3D sound field.
German Golem has more details and several hi-res photos. Via Engadget.
Yamaha already has the YSP-1 sound projector on the market, but it has a much higher price point. The YSP-1 has more speakers. Will be interesting to see the first reviews coming up to see if there is any difference in sound quality in both sound projectors.
