Been using this same Motion Sound KP100S setup (with replaced bass speaker) for all my smaller gigs (for well over a year) and continue to be very happy with the results. I prefer the portable Motion Sound system over the Logitech (or other 3 piece satellites (2) + sub woofer configuration speakers such as the Tyros MS01 or Yamaha YAMaha YST50's) because the KP100S's sound is projected directly into the audience. In addition, the KP100S is built rugged & setup quick, as there are no thin wires to get tangled up or broken. For a unit which will survive frequent daily gig transport/setup, I recommend the KP100S. - Scott
