Sounds good. Tom's Hardware has good reviews, but remember: They are reviewing this piece of equipment for what it is, computer speakers for home use.
I was less than enthusiastic about the Z-2200's ability to reproduce my vocals at moderate volumes without distortion.
I currently perform with two Yamaha MS-100 speakers that are rated at 100 watts each. The Logitech Z-2200 is rated at 200 watts. The Yamahas, while way more expensive, do go a lot louder.
The Logitechs are definitely the best for the buck: $100 plus or minus. It might be perfect for audiences of 40 or less. Don't expect to buy it and to be able to sell your JBLs or Mackies.
The Z-2200 was very bass heavy in sound reproduction. It looks like the Z-2300 has better sound balance at the cost of overall volume.
