12 INCH 700W CERAMIC MAGNET BASS-MID LOUDSPEAKER (AC317V-B5Gs-8)

The AC317V/B5Gs is an Australian made ceramic magnet large excursion 12″ bass-mid loudspeaker engineered for use in professional bass-mid sound reinforcement systems and musical instrument applications. This model is primarily designed for two-way applications requiring 700W program capacity, the large linear +/-6mm excursion permits the reproduction of extreme levels with clean fundamental bass notes.  The high-power rating is achieved with a 70mm coil and high temperature materials, through magnet cooling and thermal coupling to a massive die-cast aluminium chassis for heat dissipation. The AC317V range features die-cast aluminium frame, CNC precision components. The ferrite magnet-assembly is FE optimized; the bumped rear-plate permits large voice coil excursion without damage.  Shaped pole improves BL linearity, lowers distortion and improves stability. The aluminium shorting ring reduces flux modulation, improves stability and enhances thermal dissipation. Wind noise is reduced with an undercut and flared vented pole-piece. The steel components are E-coat finished for superior corrosion resistance. The stiff damped cone is product of our OFP technology and is molded in-house from a blend of premium air dried wood pulp and Kevlar fibres resulting in smooth mid response.  The spider is made of Aramid material chosen for its high rigidity and long term stability in demanding applications. The spider and accordion cloth surround have been designed to not compromise the peak linear excursion thus ensuring peak excursion levels are delivered with minimal distortion.
