Donny, I agree that the 'initial' cost out lay of 3 piece (2 satellite +1 subwoofer) system is substantially cheaper than the Motion Sound KP100S, but over the long haul, I think the KP100S a better deal ($ value), especially if you do a lot of small gigs regularly.

With 3 piece (2+1 subwoofer) systems, I've found it a continous hassle to have to deal with untangling their 1/8" ultra thin gauge wires which have a tendency to break & short out so easily, especially with repeated daily setup & breakdown. For occasional gigging the 2+1 setup is fine, but if you need a 'one piece' stereo lightweight portable PA unit for small venues (less than 50 people) which affords 'quick setup' & which can withstand the rigors of daily gig transport/setup, then imho, the Motion Sound KP100S remains the best $ value. - Scott
