Comments about Kurzweil KS-40A Powered Studio Monitor 4" (Pair):

Got these at the stupid deal of the day price to replace my desktop speakers. Sound quality and volume is much better than what you get at a similar price from "Creative" or Logitech. All controls are on the rear of the speaker so that's a little less user friendly.
