This is the wireless surround sound system that provides both easy, plug-and-play setup and superior audio performance without speaker cables. Unlike systems subject to WiFi dropouts or Bluetooth’s latency, this model uses a WiSA (Wireless Speaker & Audio) technology that operates on interference-free 5.8 GHz frequencies. Without the complexities involved with configuring speakers through an audio receiver, its 5" H x 12 1/2" W x 7 3/4" D center control unit/front speaker wirelessly transmits 5.1 channels of 24-bit uncompressed audio to two 12 1/2" x 4 3/4" W x 7 3/4" D front speakers, two 5" H x 8" W x 4 1/4" D rear surround speakers, and one 17 3/4" H x 12" W x 13" D subwoofer. Providing the same flexibility as an audio receiver, the control unit has three HDMI inputs that accept connections from a cable box, satellite dish, gaming console, DVD-BluRay player, or a streaming appliance; also includes 3.5mm and optical inputs. The entire system engages 14 custom-designed drivers and six class-D amplifiers; the rear surround speakers each have two full-range drivers placed on opposite sides of the enclosure to provide a widespread, enveloping surround sound experience.
