Wow! What a beast of a system this is. Hope the neighbors don't ring noise control on me. : – )

Thinking of upgrading your PC's speakers or just want a low cost surround sound set up for use with a TV and games console? Then Logitech might have what you're after with the Z906, the follow up to the company's popular Z-5500 system.

Logitech's Z-5500 5.1-channel speaker system was legendary for its beefy amp and beastly subwoofer, its plethora of optical and digital input options, and its ability to decode popular surround-sound codecs.

Surround sound; a beefy subwoofer; and plenty of inputs

Satellites have one-way drivers; no HDMI pass-through; can't decode Dolby TrueHD or DTS-HD Master Audio

This system rocks hard. This is much better than that previous z5500 The system is more present and sounds muck clearer that the z5500.

Conclusion The $400 Logitech Z906 5.1 speakers provide a pleasing surround system for watching movies. Dialogue is clear with good separation in each channel. The bass is deep and the system has the ability to provide satisfying levels of sounds.

Going by the numbers, the Z906 has all the makings of a solid 5.1 setup for the living room or PC / game room. It's capable of pumping out 500 watts (RMS), with 165 watts going to the 8-inch, side-firing subwoofer.
