For Sale and in perfect working condition is my audio system used with my PC/Mac. The system is the Cambridge SoundWorks Audio Slim 500 system. This system comprises Sub Woofer, Sat-alight Speakers, all cables and power cables/power adapter. Made under the Creative Zen stable (I believe) these speaker system was considered to be as good as the Harmon Kardon system recommended for use with computers to boast the audio sound and give a realistic and pounding beat through the sub-woofer.
