The Resolution 4S is a three-way mid-high skeletal loudspeaker, specifically designed to be cost effective by dispensing with the touring features (enclosure and flying equipment) in fixed installation applications.  It offers uniform and controlled dispersion with sound quality equal to that of the enclosed versions. The Resolution 4S is suited to a wide range of applications including demanding club and theatre venues. 


Also available with a passive high frequency crossover, the R4S can be bi-amplified to minimise overall system cost.  The mid-high horn section can be supplied rotated through 90° to facilitate horizontal use where ceiling height is restricted.

Product Rating

“By far the best service I’ve ever experienced. I was importing a product to Canada and the whole experience was quick, easy and seamless. These guys really care about running a good business. Not to mention the price was cheaper than the stores here even after importing. Definitely will do more business in the future.”
