BRAX MATRIX ML165 PRO
Handcrafted 165 mm / 6.5” High-End Woofer
The BRAX MATRIX ML165 PRO represents the next evolutionary stage of the legendary MATRIX ML6 D – a loudspeaker that has long been regarded in the high-end world as a benchmark for natural music reproduction. With a refined technical design, state-of-the-art materials and uncompromising attention to detail, it has been further developed to elevate midbass performance to an unprecedented level.
The result is a loudspeaker that reproduces music with impressive authority, exceptional precision and emotional depth – created for sound enthusiasts who accept no compromise.
Features
- Ultra-lightweight carbon fleece multilayer cone – combines superior stiffness-to-weight ratio with reduced resonance for precise, natural and highly dynamic sound reproduction
- Copper cap on the pole core – minimizes voice coil inductance, linearizes impedance at high frequencies, and enhances efficiency for greater transparency and refined upper-frequency response
- Hemispherically shaped dust cap – optimizes the upper midrange response for seamless tonal transitions and exceptional detail resolution
- Aerodynamically shaped aluminum die-cast basket – allows ideal voice coil ventilation while minimizing airflow noise for consistently high performance even at demanding levels
- High-strength Nomex spider – crafted from meta-aramid fabric to ensure exceptional shape stability and long-term reliability even under demanding conditions
- Specially shaped rubber surround – crafted from premium butyl enables maximum linear cone excursion with minimal distortion
- Ultra-precise machined magnet system – guarantees optimal symmetrical magnetic flux, outstanding impulse accuracy and powerful low-frequency performance
- Vented pole core and spider – enhances airflow within the magnetic system and reduces compression effects for consistent performance even at high sound pressure levels
- Massive 24-carat gold-plated terminals – guarantee maximum conductivity and signal quality
- Made in Germany – developed and manufactured for uncompromising sound quality at reference level
Carbon-fleece multilayer cone – light, rigid and resonance-free
The newly developed carbon fleece multilayer cone of the ML165 PRO was designed and manufactured in close collaboration with renowned specialist Dr. Kurt Müller. Its layered carbon structure combines extreme stiffness with minimal mass, effectively reducing unwanted resonances. A specially shaped reinforcement collar on the rear – directly at the transition to the surround – significantly increases torsional stiffness and prevents deformation even at high excursion levels. The straight cone geometry at the voice coil former optimizes power transfer and ensures exceptionally precise and controlled sound radiation.
Copper cap for maximum linearity
At the heart of the motor assembly is a copper cap on the pole core. By generating controlled eddy currents, it damps fluctuations in the magnetic field, reducing voice coil inductance, linearizing impedance in the high-frequency range and significantly lowering distortion. The result is a smoother frequency response, higher efficiency and remarkably natural reproduction even in the upper frequency range.
Precision and perfect control
The precisely crafted magnet system of the ML165 PRO provides a stable, symmetrical magnetic flux, ensuring exceptional impulse fidelity and powerful dynamics across the entire frequency range. The aerodynamically shaped aluminum die-cast basket allows ideal voice coil ventilation, minimizes airflow turbulence and guarantees maximum thermal stability with minimal compression effects, even at high output levels.
The specially designed rubber surround enables exceptionally linear cone excursion with minimal distortion. Its highly damped material ensures exact centering and precise control even at maximum excursion, while the high-strength Nomex spider with its dimensionally stable fabric maintains consistent centering and long-term mechanical durability. The result is controlled bass response and a clean, natural midrange presentation.
Massive 24-carat gold-plated terminals ensure maximum conductivity and absolute signal integrity – an essential contribution to uncompromising reference-level sound quality.
Elegant design – functional and aesthetic
With its refined design, the ML165 PRO conveys a visual impression that perfectly complements its outstanding acoustic performance. The fine, silk-matte surface of the cone, the matt black powder-coated aluminum basket and the golden accent ring around the dust cap give it a distinctive, elegant character – perfectly suited for seamless integration into any vehicle interior.
Made in Germany – reference-level sound culture
Like every loudspeaker in the BRAX MATRIX series, the ML165 PRO is crafted in Germany with the highest precision and assigned an individual serial number registered in the BRAX database. Every pair is delivered in an elegant, tailor-made wooden box and represents uncompromising craftsmanship, audiophile passion and reference-level sound culture.

FAQs
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.
