It all began with the vision of music lover and company founder Heinz Fischer being the first to bring the terrific audio experience of legendary high-end hi-fi components into the car. Uncompromising in design, technology and sound. True to this guiding principle, the focus of the new development of our BRAX GRAPHIC loudspeaker series was on pure, unadulterated music reproduction, consistently implemented with the latest technologies and the highest quality materials – of course Made in Germany.

For the first time, the 25 mm / 1 “high-end tweeter BRAX GRAPHIC GL1 incorporates an innovative ceramic-aluminum dome into the BRAX loudspeaker series: In a complex manufacturing process, a ceramic flame is melted onto the surface of the aluminum base support by a plasma flame. The result is a calotte with extreme stability and low moving mass and high internal damping – ideal for a brilliant and compression-free high-frequency reproduction with excellent fine resolution. The integrated coupling volume, which is dampened with merino wool, ensures a low resonance frequency and thus the possibility of a deep acoustic coupling.

The purist design of the stainless steel housing turned out of solid does not only look classy, ​​it also ensures optimal heat dissipation. The mounting ring with fine thread on the back of the housing allows a particularly discreet integration into the vehicle interior. Recessed, 24-carat gold-plated connector sockets ensure maximum conductivity, the precision-crafted, 12-times ventilated neodymium magnet optimally linear magnetic flux and the sturdy grid provides reliable protection of the calotte.

As is typical for BRAX, each pair of loudspeakers is provided with its own serial number and recorded in a service database. This high-end product – made in Germany – is also rounded off by the packaging in a noble wooden box, which underlines once again the philosophy of the BRAX brand.
