Product features

Before replacing a factory speaker, check its mounting space, impedance and connection. BRAX GRAPHIC GL3 MK2 is the BRAX speaker option described below. Its specifications help you match the driver to the amplifier and installation, rather than buying on diameter alone.

What it does

  • Very stiff lightweight paper cone with unique “MicroSphere” coating consisting of micro ceramic hollow spheres embedded in a polymer layer
  • Low reflection rubber surround for smooth high frequency roll off
  • Aerodynamically shaped aluminium diecast basket with optimised voice coil ventilation
  • Polyurethane dustcap for optimisation of the frequency response in the upper midrange area
  • Ultra precise machined, vented neodymium magnet system for highest magnetic flux linearity
  • Solid stainless steel ring BRAX MR3 optionally available, which can either be used as mounting ring or grille support ring depending on mounting position
