Brax Graphic GL3 MK2: 3.15" / 80mm high-end cone midrange speaker
Brax was founded on the vision of transferring high-end audio performance into a car environment without compromise. The Graphic speaker series is the result of that pursuit — exceptional components and craftsmanship, made in Germany.
Features
- Stiff, lightweight paper cone with "MicroSphere" coating — 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 to optimise frequency response in the upper midrange
- Ultra-precision machined, vented neodymium magnet system for highest magnetic flux linearity
- Optional solid stainless steel ring Brax MR3, usable as a mounting ring or grille support ring
Progression in Perfection
The GL3 MK2 introduces a new dustcap made from exceptionally soft polyurethane, delivering a more balanced frequency response in the upper midrange and greater tonal neutrality compared to its predecessor.
A perfect team with maximum tonal harmony
The GL3 MK2 pairs with the GL1 MK2 tweeter and GL6 MK2 mid-woofer to form a complete three-way system within the Brax Graphic series. Its wide frequency range and dynamic character make it well suited to fully active setups.
MicroSphere – the material for maximum acoustic precision
The cone uses a patented MicroSphere coating: ceramic hollow spheres of just 75 µm diameter are embedded in a polyamide layer applied directly to the cone surface. The result is highly precise, detailed reproduction that integrates naturally with the rest of the Graphic series.
State-of-the-art technology
A linear push-pull neodymium magnet system drives the cone within a die-cast aluminium basket. The long-stroke voice coil is well-ventilated for thermal stability and to prevent compression. The soft rubber surround keeps resonance frequency low, enabling a low crossover point — ideal for fully active systems.
Details thought through
Each pair carries its own serial number, registered in the Brax service database. The GL3 MK2 is supplied in an elegant wooden box, reflecting the uncompromising standards of the Brax brand.

About the Brax 55034
From our tech experts at CEN
The Brax Graphic GL3 MK2 is an 80mm high-end cone midrange speaker pair, rated at 100W RMS and 150W max with a 3-ohm impedance. The paper cone features Brax's patented MicroSphere ceramic coating, driven by a vented neodymium magnet system. Made in Germany, it is built for active three-way car audio installations.
Who it suits
These suit serious car audio enthusiasts building an active three-way system within the Brax Graphic range. They work as a matched set with the Brax Graphic GL1 MK2 tweeters and Brax Graphic GL6 MK2 mid-woofers for full tonal cohesion across the range.
Our tech experts advise
The GL3 MK2 needs a 76mm cutout diameter and 35.5mm installation depth. An active crossover or DSP is required; these are not passive drop-in replacements. Each pair carries its own serial number and is supplied in a wooden box. Fitting is priced per vehicle — visit our Nottingham car audio installation page to arrange a quote.

Frequently Asked Questions
Q: Will these speakers fit my car?
A: Most car speakers are standard sizes, but mounting depth and fitting rings vary by vehicle. Check the size in the Specification tab against your vehicle, or contact CEN with your registration and we will confirm fitment and any adapters or fitting kits you need.
Q: Do I need an amplifier to run these speakers?
A: Not always. Most speakers will run from a standard head unit, but a dedicated amplifier lets them perform at their best, particularly for component sets and higher power handling models. The RMS figure in the Specification tab is the guide to how much clean power they can use.
Q: What is the difference between coaxial and component speakers?
A: Coaxial speakers combine the tweeter and woofer in one unit for a simple like-for-like upgrade. Component sets separate the tweeter and woofer with a crossover for better imaging and detail, and suit installs where sound quality is the priority.
Q: Do these come as a pair?
A: Unless stated otherwise, car speakers are sold in pairs. Check the product title and What's Included tab, which lists exactly what is in the box.
Q: Can CEN fit these speakers for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
Q: What impedance is the GL3 MK2?
A: The GL3 MK2 is a 3 ohm midrange with a DC resistance of 2.9 ohms. Make sure your amplifier is stable at this load.
Q: What should I pair the GL3 MK2 with?
A: BRAX designed it to work with the GRAPHIC GL1 MK2 tweeter and GL6 MK2 mid-woofer as a three-way system, ideally run fully active.
Q: Is a mounting ring included with the GL3 MK2?
A: No. The box contains two GL3 MK2 midranges, an Allen key and a data sheet. The solid stainless steel BRAX MR3 ring is available separately as a mounting or grille support ring.
