Brax ML165 PRO 6.5" High-End Woofer MATRIX Series

The BRAX MATRIX ML165 PRO is a midbass speaker from the BRAX MATRIX series, developed as an evolution of the MATRIX ML6 D model. Designed for high-end audio reproduction, it integrates materials and technical solutions oriented toward sonic precision, excursion control and distortion reduction.

The multilayer carbon fleece membrane, developed in collaboration with Dr. Kurt Müller, combines lightness and rigidity to limit unwanted resonances. The magnetic system with copper cap reduces voice coil inductance and contributes to improved linearity and frequency response.

The aerodynamic die-cast aluminum basket promotes voice coil ventilation and thermal stability. The rubber surround and Nomex fabric spider ensure precise excursion control and stable centering of the moving assembly. The structure is completed by 24-karat gold-plated terminals, designed to guarantee high electrical conductivity.

The design features a membrane with matte silky finish, a matte black basket and a golden ring around the dust cap. The BRAX MATRIX ML165 PRO is manufactured in Germany. Each unit has an individual serial number registered in the BRAX database and each pair is supplied in a custom-made wooden case.

ML 165 PRO Features

  • Ultralight multilayer carbon fiber cone - combines excellent rigidity-to-weight ratio with reduced resonance for precise, natural and highly dynamic sound reproduction
  • Copper cap on pole core - minimizes voice coil inductance, linearizes impedance at high frequencies and improves efficiency, ensuring greater transparency and refined response at high frequencies
  • Hemispherical dust cap - optimizes response in the mid-high range for smooth tonal transitions and exceptional detail resolution
  • Aerodynamically shaped die-cast aluminum basket - allows ideal voice coil ventilation while minimizing airflow noise for consistently high performance even at elevated volume levels
  • High-strength Nomex spider - made of meta-aramidic fabric to ensure exceptional geometric stability and long-term reliability even under extreme conditions
  • Special-shaped rubber surround - made of high-quality butyl, allows maximum linear cone excursion with minimal distortion
  • Precision-engineered magnetic system - guarantees optimal symmetrical magnetic flux, exceptional impulse precision and powerful low-frequency performance
  • Ventilated pole core and spider - improve airflow within the magnetic system and reduce compression effects, ensuring consistent performance even at elevated sound pressure levels
  • Massive 24-karat gold-plated terminals - guarantee maximum conductivity and signal quality
  • Manufactured in Germany - developed and built for uncompromising reference-level sound quality
