When it comes to innovation, sometimes less is more: the YSP-5100, for example. Its much thinner than previous YSP models for a slimmer, more elegant appearance appropriate for your HDTV or OLED TV. Yet its room-filling surround sound is spectacular. Slightly wider than its smaller cousin, the YSP-4100 DSP, the YSP-5100 has two extra 1" balanced-dome tweeters to accommodate larger-size HDTVs.The YSP-5100 Digital Sound Projector offers great new features like HD Audio decoding, 1080p-compatible HDMI (4 in and 1 out), IntelliBeam calibration, UniVolume, and numerous listening modes. Also included are two yAired wireless accessories for connecting to your iPod/iPhone and wireless subwoofer.
