Brax MATRIX ML80 PRO

Brax MATRIX ML80 PRO – 80 mm High-End Midrange Speaker

The ML80 PRO is the midrange driver of the BRAX MATRIX series and the completely re-engineered successor to the MATRIX ML3. It keeps the uncompromising philosophy of its predecessor but uses a new concept and current materials, and is aimed at high-end car audio systems with a dedicated midrange way.

At its heart is a carbon fleece multilayer cone developed and manufactured together with cone specialist Dr. Kurt Müller, combining high stiffness with very low mass. A rear reinforcement collar at the surround transition, a straight cone geometry at the voice coil former, a solid stainless steel phase plug and a compact push-pull neodymium magnet system round off a design focused on purity, dynamics and low distortion.

Key Features

• Carbon fleece multilayer cone: layered carbon structure with a high stiffness-to-weight ratio that reduces unwanted resonances; developed with Dr. Kurt Müller.
• Reinforcement collar: a shaped collar on the rear of the cone at the surround transition increases torsional stiffness and prevents deformation at high excursion.
• Straight cone geometry at the former: improves power transfer and gives controlled sound radiation.
• Refined cone coating: finely textured, closed-pore front coating with a silk-matte look, for dimensional stability and durability.
• Solid stainless steel phase plug: optimises dispersion and minimises midrange interference.
• High-damping butyl rubber surround: suppresses surround resonances, improves cone control and resists temperature.
• Aerodynamic die-cast aluminium basket: ensures voice coil ventilation and reduces airflow noise at high levels.
• Push-pull neodymium magnet system: precisely machined for magnetic linearity, very low distortion and high power handling.
• Vented Nomex spider: meta-aramid fabric for precise centring and long-term stability; venting improves airflow between spider and magnet at high SPL.
• 24-carat gold-plated terminals: for maximum conductivity.
• Measured and paired: each unit is individually measured, paired and serial-numbered in the BRAX database.
• Made in Germany: handcrafted and supplied in a tailor-made wooden box.

Drivers & Construction

The ML80 PRO uses a 25 mm voice coil with 6 mm winding height, driven by a compact push-pull neodymium motor. The carbon fleece multilayer cone has an effective area (Sd) of 35 cm² and a moving mass (Mms) of 3.0 g, and is suspended by a butyl rubber surround and a vented Nomex spider in an aerodynamically shaped die-cast aluminium basket. A solid stainless steel phase plug sits in the centre of the cone.

Installation Notes

Outer diameter is 92 mm (3.6″), installation diameter 76 mm (3.0″) and installation depth 34 mm (1.4″). The optional BRAX MR3 stainless steel support ring with matching grille is available as a mounting solution. BRAX gives these recommendations:

• Infinite baffle: high-pass at 300 Hz, 24 dB/oct. Linkwitz-Riley.
• Sealed 0.4 L: system resonance 200 Hz; high-pass 350 Hz, 24 dB/oct. Linkwitz-Riley.
• Sealed 0.8 L: system resonance 155 Hz; high-pass 300 Hz, 24 dB/oct. Linkwitz-Riley.
• Sealed 1.2 L: system resonance 140 Hz; high-pass 250 Hz, 24 dB/oct. Linkwitz-Riley.

Sealed enclosures should always be filled with suitable damping material.
