Onkyo has introduced three new packaged home theater systems, each consisting of a flexible HDTV-capable audio-video receiver, five or seven surround-sound loudspeakers, powerful subwoofer, and an included iPod docking station on two of the systems. These systems, popularly called HTiB for “Home Theater in a Box,” can be combined with a video display, Blu-Ray or DVD player, and cable/satellite TV box to provide a complete home theater surround sound experience.

The 7.1 channel home theater receiver included with top of the line HT-S5100 offers an amazing range of capabilities at such a modest price point. The HT-R560 receiver has three 1080p compatible HDMI inputs and one output. The HDMI Pass-Thru provides optimal video quality with separate connections for the audio channels. For optimum sound quality, the highly regarded Audyssey 2EQ room correction technology automatically adjusts the sound character and time delay of each speaker relative to the listening positions. Additionally, Audyssey’s Dynamic EQ adjusts sound on the fly to optimize sound quality for any volume, particularly at low listening levels.

The HT-S5100 includes advanced Dolby and DTS surround sound processing capabilities, a powerful 130-watts per channel using Onkyo’s Wide Range Amplifier Technology (WRAT), seven loudspeakers with outstanding sound quality, and a powerful 290-watt subwoofer and is Sirius Satellite Radio ready. The HT-S5100 system also includes a new dedicated Onkyo iPod dock and charging station, plus the company’s new Music Optimizer technology to enhance the dynamic range of MP3 and AAC files which are normally compressed for headphone playback.

The more affordable Onkyo HT-S4100 and HT-S3100 are 5.1-channel systems with HDTV-capable component video switching, DTS and Dolby Digital surround processing, and five loudspeakers. The HT-S4100 has a 200-watt subwoofer and included iPod dock. The HT-S3100’s subwoofer is powered by the receiver, and there is no iPod dock with this system.

All three systems include full-function remote controls, and are available in either black or silver finishes.

The Onkyo HT-S5100, HT-S4100 and HT-S3100 will be available in April with suggested retail prices of $579, $479, and $379 each, respectively.
