The AC465Y-B3 is an Australian made professional low frequency 18″ bass loudspeaker with a useful upper limit of 2.8kHz. This model has been designed for peak linear travel of 7.5mm and capable of 21mm peak before damage. The 1500W program rating is achieved with through magnet cooling, thermal coupling to a massive die-cast aluminium frame and use of high temperature rated materials.

This model has a sensitivity of 98 dBSPL. The stiff ribbed cone is product of our OFP technology and is moulded in-house from a blend of premium air-dried wood pulp and Kevlar fibres resulting in smooth controlled mid response.

The AC465Y features die-cast aluminium 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 aluminium 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 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.
