The AC400X-B4s is an Australian made ceramic magnet 15″ bass-mid loudspeaker with a useful upper limit of 3.5KHz. The 1400W program rating is achieved with a 4″ voice coil, high temperature rated materials. High thermal rating is achieved with through magnet cooling and thermal coupling to a massive die-cast aluminum chassis. These features provide minimum thermal compression in demanding applications.

This model offers large linear diaphragm excursion Xpk 6.5mm delivering clean bass performance, high program power handling, high efficiency, therefore capable of producing extreme levels. This model features a curvilinear cone which extends the high frequency response, very suitable for electric bass requiring more detail.

The AC400X features die-cast aluminum frame, CNC precision components. The ferrite magnet-assembly is FE optimized. The bumped rear-plate permit large linear voice coil excursion and the shaped pole improves BL linearity. The aluminum shorting ring lowers distortion improves stability and enhances heat dissipation from the voice-coil. Wind noise is reduced with an undercut and flared vented pole-piece.

 The stiff curvilinear paper 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 controlled mid response.  The spider is made of aramid material chosen for its high rigidity and long term stability in demanding applications. The treated accordion cloth surround assures extreme levels with excellent linearity.
