BRAX GRAPHIC GL2
As a passionate music lover and hi-fi enthusiast, company founder Heinz Fischer had a vision: to be the first provider to bring the grandiose audio experience of legendary high-end hi-fi components into automobiles. With such an ambitious goal in mind, the implementation could only succeed with absolute uncompromising design, technology and sound. True to this guiding principle, the focus in the development of our 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.
Exceptional midrange reproduction with a wide range of applications
Curtain up for the newest member of the BRAX GRAPHIC speaker series: The BRAX GL2! This 50 mm / 2" midrange driver is something very special in many respects. In its long-term development process, no expense or effort was spared to develop an uncompromising loudspeaker that can only be expected from BRAX. Every single component - from the basket to the membrane - was reconsidered and manufactured with tools specially made for this purpose. This enormous effort manifests itself beyond the outstanding sound characteristics in an unusually compact form factor, which creates completely new installation possibilities. Even better: Due to its enormously broadband frequency response, the GL2 can even be used without an additional tweeter, which comes exceptionally close to the ideal of the point sound source and raises the spatial representation of the music in the vehicle to a whole new level. The extremely stiff aluminum membrane from Dr. Kurt Müller ensures an extremely natural mid-range reproduction with particularly dynamic sound characteristics, while the precisely manufactured neodymium magnet system with its optimally linear magnetic flux contributes to the exceptionally low distortion factor. All of this shows more than clearly: with all its technical refinements, the GL2 is in a league of its own. while the precisely manufactured neodymium magnet system with its optimally linear magnetic flux contributes to the exceptionally low distortion factor.

High quality design with functional features
As is typical for BRAX, design and function intertwine: To round off the puristic, elegant look, the 24 carat gold-plated connection sockets should not be missing to ensure maximum conductivity. The black grid provides optimal protection of the membrane from damage and underlines the minimalist look, while the threaded hole on the back allows for discreet integration into the vehicle interior.
Details thought through to the end
The special level of quality and attention to detail automatically promote the GL2 to the reference class and should satisfy even the highest sound demands of true hi-fi enthusiasts. As is usual for BRAX, each pair of loudspeakers is given its own serial number and recorded in a service database. This high-end product - Made in Germany - is rounded off by the packaging in an elegant wooden box, which once again underlines the philosophy of the BRAX brand.
