12 INCH 800W CERAMIC MAGNET BASS_MID LOUDSPEAKER (AC317V-B2s-8 )

The AC317V-B2 is an Australian made ceramic magnet large excursion 12″ bass loudspeaker engineered for use in professional sub-woofer sound reinforcement systems and musical instrument applications.  The large linear excursion of  +/- 9.0mm permits the reproduction of extreme levels with clean fundamental bass notes.  The high 800W program rating is achieved with a 3″ voice-coil and and high temperature rated materials. High thermal rating is achieved with through magnet cooling and thermal coupling to a massive die-cast aluminum chassis for optimum heat dissipation. The AC317V 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. Shorting ring reduces flux modulation, improves stability and enhances heat 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.
