Graphic GL6 Mk2
6.5″ / 165 mm High-End Woofer
Brax speakers are reference-grade components for installations where no compromise is acceptable. Designed and manufactured in Germany by the engineers behind Helix, these represent the absolute pinnacle of automotive speaker engineering. This isn’t a casual upgrade from factory speakers – Brax components demand professional installation, proper amplification, and complete system integration.
Brax – German Car Audio
It all started with the vision of music lover and company founder Heinz Fischer to be the first to bring exceptional audio experience of legendary high-end hi-fi components into the car. Uncompromising in design, technology and sound. True to these fundamental principles, the focus in the development of our BRAX GRAPHIC loudspeaker series is on pure, unaltered music reproduction, consistently realized by the latest technologies and highest-quality materials – of course designed and made in Germany.
Each pair of speakers is unique
As is typical for BRAX, each pair of speakers is given its own serial number and recorded in a service database. This high-end product – made in Germany – is rounded off by the packaging in a fine wooden box, which once again underlines the philosophy of the BRAX brand.
