Lightweight version of the Res 4 for installations

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.

A small number of aerospace aluminium composite R4S cabinets were made for the Millennium Dome.

Please note that R4/5 Neodymium drivers are no longer available. Recone kits and Ferrite (Ceramic) drivers are still available.
