I have had many speaker / subwoofer packages in my time and I have to say that this one has proven to rate somewhere in the middle.
One thing this product rates highly on is the power of the subwoofer. It provides a huge amount of base, enough to stand even a song such as Protection by Massive Attack (Which I use a general benchmark). The box looks fairly attractive in black and is compact enough to fit nicely under a computer desk.
The speakers produce fairly good sound quality, however I have certainly had better in the same price range. Also, the speakers do look and feel a little tacky. I also found it a little strange that the power of the subwoofer seems to be far greater than can be coped with by the speakers. However, you can easily plug in your own speakers to the system.
The subwoofer has it's own bass and volume control which is useful and because the system is connected to the computer by a headphone jack, it means it can also be connected to any other peice of equipment with a headphone socket, such as a television, for surround sound.
