Summary: Under the right conditions , (testing which direction to point the speaker which sounds best) , it really sounds good for the size of the speaker . I have mine hidden in a cabinet , which for some reason , sounds the best in overall frequency response that will blend in the the mid-range speakers . The wire connections are pretty solid , and there is no static , even when near other power wires . I was able to turn it all the way up while playing a bass track .
Excerpt: We have two logitech Z-2300 speaker sets, with one being connected to my gaming computer, and the other is on a Yamaha electronic drum set. Both of these older speaker sets are remarkable in their performance (they're 200 watts as well.) The Logitech Z623 Speaker System surpasses the Z-2300 exponentially with much clearer highs and mids. You can still turn up the lows (the control is on one of the main speakers) if you want to rattle the windows in your house- literally.
Summary: If you keep in mind that these are 2.1 computer speakers then I don't see how you could be anything but pleased with them. They sound excellent and the power, volume, and bass controls, as well as a headphone jack and line in jack all on the right hand speaker are very convenient. They are well made and have plenty of power for typical computer use.
Summary: I bought this to serve as a computer audio monitor. Being a lifelong musician and high-end audio enthusiast, I didn't expect to get much for under $100.00---I was dead wrong! The quality of this product is first class; the sound is clear and very well balanced with a smooth response curve. My ears do not become fatigued after long periods of listening.
Summary: These are the best speakers I've ever owned. Worth every cent I spent on them. Great highs, superb lows, very crisp & clear sound. I didn't know Logitech could produce such a high-quality speaker. They sound as good as the speakers in the Bose presentation at the store. Seriously.
Great value for your money, a must-buy for immersive audio

Summary: Originally, I was pretty skeptical of the THX certification, but I was completely wrong. This product surpassed all expectations I had for it. Logitech definitely did not disappoint, and I highly suggest this speaker system. The two satellite speakers produce some good sound and fit comfortably as computer speaker next to a monitor.
Excerpt: I did quite a bit of research about this system, knew I wanted one. I use the system in my garage/mancave hooked up to my IPOD. Great sound all thru the spectrum with amazing bass response from subwoofer. The price was very pleasing. I highly recommend this system.
