The Denon DHT391XP raises the performance bar for "HTIB" systems. It features the powerful Denon AVR391, a 5.1 channel home theater AV reciever boasting 3D compatible, 1080p capable HDMI 1.4a repeating technology (4 in, 1 out). This allows simple one cable connectivity to any HDMI equiped HD TV. The HDMI connectivity also supports the latest generation surround sound formats available on Blu-ray disc, including Dolby TrueHD and DD+, dts-HD and DTS-HR. The AVR-391's 5 x 110-Watt (6-ohms, 1kHz) amplifier section features discrete circuitry to deliver detail and dynamics to your music and movie selections. Complimenting the AVR-391 is a relatively compact, yet powerful 5.1 speaker package. The front speakers are a 2-way "LCR" design using dual 3-inch woofers flanking a 1-inch tweeter. The surround speakers feature a 3-inch full range driver. Providing depth and impact is an 8-inch, 100-watt powered subwoofer. Combined with the AVR-391, this package delivers 650-watts of total system power. That's a lot of bang for the buck! Enough to please any value orientated movie and music enthusiast. ..
