Brax ML3 -  Midrange 80 mm - Pair

.

The new BRAX MATRIX ML3 cone midrange drivers are a masterpiece in themselves - handcrafted in Germany using the latest technology and the highest quality materials. However, they fully demonstrate their perfection as part of a high-quality, fully active sound system. Here they impress with the exceptional sound and level capabilities that you would expect from a product from the reference brand BRAX.

The design signals high quality, the exquisite components “Made in Germany” guarantee the best functionality and pure, unadulterated music reproduction. The aerodynamically shaped die-cast aluminum basket ensures optimal voice coil ventilation, and an extremely low-reflection rubber surround ensures an incomparably balanced frequency response in the upper transmission range.

The extraordinarily stiff and very light paper membrane with a new “MicroSphere” coating makes a further contribution. With this patented technology, hollow ceramic microspheres with a diameter of only 75 µm are integrated into a polymer layer and applied to the membrane. This special coating not only increases the stiffness of the cone, but also its internal damping. Instead of weighing you down, this unique stabilization ensures lightness, lower overall quality and outstanding precision in sound reproduction.

In order to meet our high quality standards, the loudspeakers are hand-selected for perfect sound interaction and are only put together in pairs based on their acoustic parameters and recorded in a service database with a serial number. The packaging in an elegant wooden box completes the whole thing and once again underlines the high-end philosophy of the BRAX brand. A stainless steel mounting ring set including grille (MR3) is optionally available. Depending on the installation position, the solid stainless steel ring can be used as a mounting ring or to hold the grille.
