Graphic GL3 Mk2

3.15″ / 80 mm High-End Cone Midrange Speaker

 

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. 

It all started with the vision of the passionate music lover and entrepreneur Heinz Fischer to transfer the sound experience of legendary high-end audio components into an automobile environment without making any compromises in terms of design, technology and sound. Following this, our engineers focused on exceptional sound quality and once again pushed the technological limits when they designed our BRAX GRAPHIC speaker series. Outstanding components and unparalleled craftsmanship – solely made in Germany!
