I recently installed my new QS8's as part of a 5.1 setup. These speakers rock! The sound diffusion is phenomonal! Bass response is impressive as well. Mounting to the wall was straight forward w/the included bracket. Just be sure to use large screws, becuase these things weight nearly 12lbs each! I highly recommend these speakers. To me, the gauge of a good product, is the volume of ads for used items for sale. Finding ads used QS8's or any other Axiom products are few and far between.
