European Manufacturer: Yes


As a passionate music lover and hi-fi enthusiast, company founder Heinz Fischer had a vision: to be the first manufacturer to bring the magnificent audio experience of legendary high-end hi-fi components into the automobile. With such an ambitious goal in mind, success could only be achieved through an absolute refusal to compromise on design, technology, and sound. True to this guiding principle, the focus during the development of our GRAPHIC speaker series was on pure, unadulterated music reproduction, consistently achieved using the latest technologies and the highest-quality materials—and, of course, Made in Germany.

Exceptional midrange reproduction with a wide range of applications
Curtain up on the newest member of the BRAX GRAPHIC speaker series: the BRAX GL2! This 50 mm / 2” midrange driver is something truly special in many ways. Throughout its lengthy development process, once again, no expense or effort was spared to create an uncompromising speaker, as one would expect only from BRAX. Every single component—from the basket to the diaphragm—was reimagined and manufactured using custom-made tools. This enormous effort is reflected not only in the outstanding sound quality but also in an unusually compact form factor that opens up entirely new installation possibilities. Even better: Thanks to its exceptionally wide-band frequency response, the GL2 can even be used without an additional tweeter, which comes exceptionally close to the ideal of a point source and elevates the spatial imaging of music in the vehicle to an entirely new level. Dr. Kurt Müller’s extremely rigid aluminum diaphragm ensures exceptionally natural midrange reproduction with particularly dynamic sound characteristics, while the precision-engineered neodymium magnet system, with its optimally linear magnetic flux, contributes to an exceptionally low distortion factor. All of this makes it abundantly clear: with all its technical refinements, the GL2 is in a league of its own.

High-quality design with functional features
As is typical for BRAX, design and function go hand in hand: To round out the minimalist, elegant look, the 24-karat gold-plated connectors—which ensure maximum conductivity—are, of course, a must. The black grille provides optimal protection for the diaphragm against damage and emphasizes the minimalist aesthetic, while the threaded hole on the back allows for discreet integration into the vehicle’s interior.

Thoughtful Attention to Detail
The exceptional level of quality and attention to detail automatically elevate the GL2 to the reference class and should satisfy even the highest sound standards of true hi-fi enthusiasts. As is customary for BRAX, each pair of speakers is assigned its own serial number and recorded in a service database. This high-end product—Made in Germany—is further enhanced by its packaging in an elegant wooden box, which once again underscores the BRAX brand philosophy.


Features:

  • Extremely wide-band frequency response even off-axis—making it ideal for use as a full-range speaker without an additional tweeter
  • Rigid aluminum diaphragm for outstanding and natural midrange reproduction
  • Thanks to the sturdy and lightweight aluminum diaphragm, the sound is particularly lively and dynamic
  • Precision-engineered neodymium magnet system for optimal linear magnetic flux
  • 24-karat gold-plated connectors for maximum conductivity
  • Magnetic system with a threaded hole for concealed mounting from the back
  • Sturdy grille for optimal protection of the diaphragm against damage
  • Aerodynamically optimized basket
  • Extremely compact dimensions, ideal for installation in the A-pillar—outer diameter nearly identical to that of the BRAX GRAPHIC GL1 tweeter

Frequently asked questions about the BRAX GRAPHIC GL2 speakers

How are the BRAX GRAPHIC GL2 speakers fitted in the car?

The compact design, with a diameter of 50 mm/2" (outer diameter just 60 mm), allows for installation options that are not possible with larger midrange speakers – such as in the A-pillar. To fit it, use the mounting clips supplied; the sturdy grille also protects the diaphragm from damage.

What are the BRAX GRAPHIC GL2 used for – mid-range drivers or full-range speakers?

The GL2 is designed as a full-range cone midrange driver (frequency range 400 Hz – 20,000 Hz) and, thanks to its exceptionally wide-band frequency response, can even be used without an additional tweeter. This comes particularly close to the ideal of a point source and improves the soundstage within the vehicle.

What material is the BRAX GL2’s diaphragm made of?

The GL2 features an extremely rigid aluminium diaphragm designed by Dr Kurt Müller with a low moving mass (1.6 g). This combination reduces distortion and enables precise, dynamic reproduction in the midrange with a low total harmonic distortion.

What is the power handling capacity of the BRAX GRAPHIC GL2?

The GL2 is rated at 80 watts RMS / 120 watts maximum at 4 ohms impedance (high-pass filter from 400 Hz, 24 dB/octave). It is therefore clearly designed for precision rather than sheer power – for optimal use, please note the recommended crossover frequency of your DSP system.

Can the GL2 be combined with the BRAX GRAPHIC GL1 tweeter?

Yes, the GL1 tweeter complements the GL2 to form a well-matched system – the outer diameters of both drivers are almost identical, which ensures a particularly uniform appearance when installed. Both components are from the same GRAPHIC series and blend harmoniously in terms of sound, resulting in a consistent frequency response.

What magnet system does BRAX use in the GL2?

The GL2’s magnetic system utilises a precision-machined neodymium drive to ensure an optimally linear magnetic flux and a compact design. This ensures a controlled excursion and contributes to the exceptionally low total harmonic distortion.

How is the BRAX GRAPHIC GL2 pair of speakers delivered?

The pair of speakers, each with its own serial number, comes in an elegant wooden box, complete with mounting brackets, an Allen key and a technical data sheet. The 24-carat gold-plated terminals and the ‘Made in Germany’ manufacturing by Audiotec Fischer underline the high standard of craftsmanship.

What should I bear in mind when storing and handling the GL2?

Store the chassis in the wooden box in a dry, dust-free place whilst they are not fitted. When fitting them, avoid applying pressure to the diaphragm so as not to damage the delicate aluminium diaphragm.
