Wiring Wizard & Port Calculator

Use our wiring assistant for easy speaker and subwoofer connections! The correct connection is important for your amplifier! Low-impedance operation can damage the amplifier! The datasheet shows you which connection each amplifier is designed for!

Our port calculator shows you the tuning characteristics of your enclosure! The net volume is always particularly important here; calculate the subwoofer’s actual resonant chamber volume beforehand to get the correct result. The net volume is calculated by subtracting all dead spaces and is crucial for enclosure design.

It all began with the vision of music lover and company founder Heinz Fischer: to bring the magnificent audio experience of legendary high-end hi-fi components into the automobile without making any compromises in design, technology, or sound. True to this guiding principle, the focus during the development of our new BRAX 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.

Progression Toward Perfection
In keeping with BRAX’s signature philosophy and high standards, it is essential to continuously refine every detail through our relentless pursuit of perfection. As a result, the new GL3 MK2 now features a new dust cap made of exceptionally soft polyurethane for an even more balanced frequency response in the upper midrange and, consequently, maximum tonal neutrality.

The Perfect Team with Maximum Sonic Harmony
The high-end GL3 MK2 cone midrange driver, when paired with the GL1 MK2 tweeter and the GL6 MK2 low-midrange driver, is the ideal complement for exceptional three-way configurations in the BRAX GRAPHIC series. Its lively, dynamic sound characteristics and exceptionally wide frequency range make the GL3 MK2 the perfect choice for top-tier acoustic performance.

MicroSphere – the material for maximum acoustic precision
At the heart of this midrange driver is its exceptionally lightweight paper cone with a modified “MicroSphere” coating, which, with its extremely precise and detailed sound reproduction, harmonizes perfectly with the other speakers in the GRAPHIC series. In this patented technology, ceramic micro-hollow spheres with a diameter of just 75 µm are embedded in a polymer layer and applied to the cone.

State-of-the-art technology
The diaphragm is driven by a highly linear push-pull neodymium magnet system, which is integrated into the aerodynamically sophisticated die-cast aluminum basket. The perfect ventilation of the long-throw voice coil not only ensures excellent thermal stability but also prevents compression effects from occurring in the first place. The soft diaphragm suspension ensures an extremely low resonance frequency, enabling deep coupling—ideally in fully active systems.

Attention to Detail
The attention to even the smallest details establishes the GL3 MK2 as a reference-level BRAX loudspeaker that consistently meets the highest sonic standards.
As is typical 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:

  • An exceptionally rigid and very lightweight paper diaphragm with an innovative “MicroSphere” coating consisting of ceramic micro-hollow spheres embedded in a polymer layer
  • Low-reflection rubber surround for a balanced frequency response in the upper frequency range
  • Polyurethane dust cap designed to optimize the frequency response in the upper midrange
  • Aerodynamically shaped die-cast aluminum basket with optimal voice coil ventilation
  • Highly precision-engineered, vented neodymium magnet system for optimal linear magnetic flux
  • A sturdy BRAX MR3 stainless steel ring is available as an option; depending on the installation position, it can be used as a mounting ring or to hold the grille in place

Frequently asked questions about the BRAX GRAPHIC GL3 MK2 loudspeaker

What is the diameter of the GL3 MK2 cone mid-range driver?

The BRAX GRAPHIC GL3 MK2 is an 80 mm cone mid-range driver (outer diameter 92 mm, mounting diameter 76 mm). This compact diameter enables precise reproduction of the mid-frequency range and, thanks to the soft diaphragm suspension, allows for deep coupling.

Which speakers can be used with the GL3 MK2?

The midrange driver is tuned to work in harmony with the GL1 MK2 tweeter and the GL6 MK2 lower-midrange driver from the same BRAX GRAPHIC loudspeaker series. This creates a coherent three-way system with a linear frequency response.

How do I install the BRAX GRAPHIC GL3 MK2 correctly?

For optimum results, a sealed housing with a net volume of at least 250 ml is recommended. The aerodynamically shaped die-cast aluminium basket ensures mechanical stability and minimises unwanted natural resonances.

Who is the manufacturer of the BRAX GRAPHIC GL3 MK2?

The loudspeaker is manufactured by Audiotec Fischer and is ‘Made in Germany’. The company develops its high-end products in accordance with its own quality standards at its German site in Schmallenberg.

How does the GL3 MK2 differ sonically from the first generation?

The MK2 revision features a new dust cap made from exceptionally soft polyurethane, which ensures an even more balanced frequency response in the upper midrange. The aim is to achieve maximum sonic neutrality whilst maintaining a lively, dynamic sound character.

How should I store and transport the mid-range speaker?

The BRAX GRAPHIC GL3 MK2 is supplied in an elegant wooden box, which is also suitable for long-term storage. Store the midrange driver in a dry place, protected from physical impact.

Does the package contain a pair or a single speaker?

The GL3 MK2 is supplied as a pair (2 x cone midrange drivers, including an Allen key and a data sheet). This means everything you need for a stereo setup is already included.

Who is the GL3 MK2 suitable for?

The midrange driver is designed for discerning hi-fi enthusiasts who are seeking an uncompromising, high-end sound in their car – ideally in fully active three-way systems. The polyurethane dust cap and the lightweight MicroSphere diaphragm ensure detailed, precise reproduction in the upper mid-range.
