These speakers ROCK. I've tried Cyber Acoustic products against Logitech and Altec Lansing, and these speakers are by far the best in their category.Firstly, the satellite tower design includes two speakers per tower, which helps distribute sound over a greater area than with single speaker designs. This greatly improves the listening experience, as the "sweet spot" area has widened so listeners perceive full-sounding stereo from a variety of locations in a small room. Additionally this avoids the pitfalls of "small" computer speakers which sound small, like music playing from a tin box. (the CA speakers 1 level below these with a single speaker design by comparison sound MUCH worse).Secondly, the bass and speakers are very powerful for their size, and have little to no distortion even at full-volume.The sub-woofer volume is adjustable independently of the other speakers. This lets you boost bass for music genres with a lot of low-frequency sounds, such as electronic/dance or hip-hop/rap, and likewise decrease bass for genres like classical and acoustic where the bass could overwhelm the instruments or vocals.The cord is conveniently long ans contains a circular volume control with a headphone jack and aux input.NOTE: I have two of these speaker systems because a roommate dropped a satellite speaker and broke the plastic foot. They are plenty sturdy if you respect them and should last a long time if handle them carefully. I guess that also shows how good these speakers are, that they broke and I bought them again.I'm a recording enthusiast, and these speakers satisfy my needs. They are not studio monitors but it's definitely possible to create good mixes on them. They take up considerably less space than professional studio monitors and are hundreds of dollars cheaper, but the sound quality is not significantly worse than monitors I've tried. They are easily 10x better than integrated speakers in TVs, laptops, etc. and they are a few steps above every speaker set in the less than $70 price range.
