The HT-S5100 is a 7.1-channel system with an HT-R560 receiver and three 1080p HDMI inputs and one output.

It offers 130-watts per channel, has seven loudspeakers, a 290-watt woofer, and is Sirius Satellite-ready.

The HT-S5100 has an iPod dock and charging station, and Onkyo’s new Music Optimizer technology to enhance MP3 and AAC files.

Audyssey 2EQ room correction technology and Audyssey’s Dynamic EQ adjust sound.

The HT-S4100 and HT-S3100 are 5.1-channel systems with HDTV-capable component video switching, DTS and Dolby Digital surround processing.

The HT-S4100 has a 200-watt woofer and iPod dock, while the HT-S3100 doesn’t have an iPod dock.

All three systems include remote controls and are available in either black or silver.

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