12 INCH 500W CERAMIC MAGNET BASS-MID LOUDSPEAKER (AC317T-B14M-8A )

The AC317T-B14M is an Australian made ceramic magnet 12″, 500W program 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, the large linear excursion of  +/- 4.2mm permits the reproduction of high spl levels with clean fundamental bass notes. The AC317T range features die-cast aluminum 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.  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 treated “M-roll” cloth surround have been designed to not compromise the peak linear excursion thus ensuring peak excursion levels are delivered with minimal distortion. Reliable operation and high thermal rating is achieved with a 65mm coil and high temperature materials. High thermal rating is achieved via the thermal coupling to a massive die-cast aluminum chassis for heat dissipation.
