The iw60 EFX is conveniently configurable between two modes of operation: 'Cinema Mode’, where the two optimally aligned 100 mm (4.00”) Dual Concentric™ drivers generate a wide and even flow of acoustic energy over a large area for a diffuse room filling ambience, and 'Music Mode’, the direct radiating set up where the 165 mm (6.50”) constant directivity Dual Concentric™ driver produces a more localised and focused sound, highlighting the distinct separation afforded by mode programme material. In Music mode the direct radiating pattern is auto switched using a 12 V trigger. The heavily braced and comprehensively damped MDF cabinet is supplied with a paintable, flush mounting grille designed to blend seamlessly into any architectural space. A unique isolation mounting system optimises low frequency performance by controlling unwanted resonances within the install structure. A mounting frame is available as an optional pre-installation accessory to fit into standard construction 2" x 4" stud walls. The exceptionally versatile, high power handling iw60 EFX is able to extract the full potential of contemporary multi-channel soundtracks; an in wall surround / effects speaker designed to reproduce the same bandwidth and sound pressure levels as the main speakers.
