Yes, I just upgraded my speaker system yesterday and I decided to get the Logitech Z-5500’s as they looked the best and they were the loudest. Ok the first thing I noticed about this system was that it has an awesome electronic audio control system which can accept Optical audio Coax audio and 6CH Audio which is your standard audio connection that comes with pretty much all computer speakers.
I am pleased to say that this system can output 5.1 surround sound even though macs are not meant for that but because this speaker system has Optical audio I hooked it up to my Mac Pro and all speakers were outputting sound which is great plus its 1000Watts its insanely loud.
Aesthetically it looks great you can take the black cover off and it will expose the silver speaker casing which has THX and Logitech written on it which also looks great and just compliments its style. Now the pictures below have pics of it setup but it also has pics of all of its connections which I personally take interest in especially when someone is reviewing it so I put that in there for everyone, enjoy!.
