The BRAX MATRIX speaker series has stood for years for unique sound and quality characteristics.
So it is only logical that in the further development of our 165 mm woofers, the focus was on the latest technologies and high-quality materials in order to meet the BRAX brand’s claim to pure, unadulterated music reproduction.

As with the new ML10 and ML3 speakers, the unique “MicroSphere” coating on the ML6P provides outstanding sonic precision. In this patented technology, ceramic micro-hollow spheres with a diameter of only 75 μm are embedded in a polymer layer and applied to the membrane. This special coating guarantees perfect internal damping without negatively affecting the membrane weight. Instead, the innovative coating increases the rigidity of the hand-made cone and makes the mid-range speaker even more dynamic and accented.

In terms of design and technology, the BRAX philosophy is invariably continued: The subtle, elegant appearance reveals smart details such as the stainless steel phase plug for best off-axis radiation and minimized compression effects, the perfectly linear magnetic drive for minimal distortion, the multi-vented voice coil for high load capacity and a streamlined, stable die-cast basket. Used as a low-mid-range supplier, the ML6P completes audiophile sound concepts that are designed for authentic music enjoyment.

As with all MATRIX products, each pair of speakers receives its own serial number, which is recorded in a service database. This high-end product is completed by the packaging in a noble wooden box, which again underlines the philosophy of the BRAX brand. Optionally, a stainless steel mounting ring set including grid (MR6) is available. Depending on the installation position, the massive stainless steel ring can be used as a mounting ring or to hold the grille.
