The Philips HTS6600/37 is a DVD home theater system that uses a simulated surround sound to provide modern home theater technology without the clutter. Using what Philips calls "Ambisound" technology, the distinguishing feature of this package is that it splits 5.1 surround into just two speakers, which then use "the combined effect of psychoacoustic phenomena, array processing and precisely angled driver positioning" to deliver a simulation of a proper surround system, with 240 watts of power and both Dolby Digital and DTS decoding. The HTS6600/37 is also noteworthy for offering compatibility with portable devices through an MP3 player input that connects to your MP3 player's headphone jack, and a USB input for flashdrives and other portable media, plus an AM/FM tuner. The system features a DVD player with HDMI output and upscaling capability, although it is not 1080p, only 1080i and 720p.
