I acquired this about six years ago and never used it, it just sat in a box. It's supposed to be a four speaker system, however the person who owned it before lost the rear speakers. It's essentially the Pulse 420 model now - a system that came with the exact same subwoofer and just two speakers.
This system is from the early 2000s. Recently hooked it up for testing purposes, and it sounds great. Lots of bass. Each speaker is 5 watt, they were called satellite speakers because they are light and can be wall mounted. The subwoofer is 15 Watt, in total it is a 25 Watt system.
