I own this system and it can only be defined as anything but a computer speaker system... it offers so much more. This set has 290 watts RMS and well over 500watts continuous. It has a bash amplifier that sends 150W RMS to the sub and 70W RMS to each of the satellites which way 6lbs a piece. This set comes with a newly designed speaker drivers that uses new materials and new crossovers that give this set a unique and superb sound- I happen to own Polk TSI100 bookshelf speakers and a klipsch 2.1 set. These cambridge soundworks speakers are much clearer and incredibly powerful. They have Injection Molded CoPolymer Cone Woofers and aluminum tweeters. They are not harsh at all because of the superior crossover topology. These are the most powerful speakers I have ever seen offered in a computer 2.1 setup. Also for music listening these are a dream to listen to(If you buy these please replace the speaker cables with http://www.amazon.com/Cables-Go-29176-Velocity-Speaker/dp/B0002J2C4G/ref=sr_1_1?s=electronics&ie=UTF8&qid=1325168209&sr=1-1 .
I also recommend this...
This is easily a $500-$600 sound system if you pieced it together separately. This system is very accurate and uncolored. The soundstage is mindblowing. Also, until you hear the satellite speakers you will not fully appreciate them. Cambridge soundworks is known for making speakers with small drivers that produce sound that usually only comes from much larger systems while being more accurate with less distortion.
I previously owned a set of creative 5700 computer speakers as well and these don't even compare. For music listening a 2.1 setup is so much better.
If you buy these speakers you must buy a good soundcard for your computer or an external DAC to get everything out of them. I have my cambridge soundworks speakers hooked up to an asus stx soundcard which is specifically designed with a burr brown digital analog converter made for stereo analog setups like this one. There is ZERO background noise and I can assure you of that. These speakers are a must have, they will knock down walls and are incredible at low volumes as well.
