Onkyo HT-S5500

This is another relatively traditional surround sound setup, but one for those who crave complete separation – audio that seems to come at the listener from specific, discrete directions, rather than being blended into zones. So as a 7.1 channel system, the HT-S5500 adds two speakers (as compared to a 5.1 system), which are placed directly to the right and left of the audience. The overall effect is extremely immersive, even if it does require hiding even more cables throughout the room. Good news: Since this is a Home-Theater-in-a-Box, it includes a receiver.
