Brax Graphic GL6 Woofer

Description

BRAX GRAPHIC GL6 MK2

Perfection in Automotive Sound

It all started with the vision of music enthusiast and company founder Heinz Fischer: to bring the exceptional audio quality of legendary high-end hi-fi components into the car—uncompromising in design, technology, and sound. Guided by these principles, the BRAX GRAPHIC loudspeaker series is dedicated to delivering pure, unaltered music reproduction. This mission is achieved through state-of-the-art technologies and the finest materials, proudly designed and made in Germany.

MicroSphere – Material for Maximum Acoustic Precision

The 165 mm / 6.5" GRAPHIC GL6 MK2 mid-woofer features a unique, patented MicroSphere coating. Ceramic micro hollow spheres—each just 75 μm in diameter—are embedded in a polymer layer and applied to the hand-scooped paper cone. This coating provides excellent internal damping while maintaining low cone mass and enhancing cone stiffness, resulting in incredibly dynamic and accurate sound reproduction.

Perfection, Redefined

True to BRAX's pursuit of excellence, the GL6 MK2 introduces refinements even in the smallest components. The updated polyurethane dust cap improves midrange frequency response, ensuring exceptional tonal neutrality and a more balanced sound signature.

Every Detail Matters

Every component of the GL6 MK2 embodies BRAX’s no-compromise philosophy:

• The die-cast aluminum basket offers unmatched structural rigidity.

• The high-precision magnet system and 37 mm voice coil (3 Ohms) provide optimized Thiele/Small parameters for excellent impulse response and high efficiency.

• A specially designed rubber surround enables long, linear cone excursions.

• 24-carat gold-plated screw terminals ensure minimal contact resistance.

• A large ventilation opening reduces compression effects and improves thermal stability.

• The robust magnet cover with BRAX branding offers solid protection and elegant aesthetics.

Individually Numbered & Handcrafted

As with all BRAX products, each pair of GL6 MK2 loudspeakers is individually serial-numbered and recorded in a service database. Each set is delivered in a luxurious wooden case, emphasizing the product’s exclusivity and the BRAX brand philosophy.
