50 mm / 2″ 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.
As a passionate music lover and hi-fi enthusiast, Audiotec‘s founder Heinz Fischer had one vision: to be the first to transfer the sound experience of legendary high-end audio components to the automobile. To achieve this ambitious goal, no compromises in design, sound and technology have been made. Following these principles, our engineers focused on exceptional sound quality and expanded the technological limits once again when they designed the new BRAX GRAPHIC speaker series.
Outstanding components and unparalleled craftsmanship make the difference – of course solely made in Germany!
Features
- Enormous broadband frequency response even off-axis – therefore ideal for the use as broadband speaker without additional tweeter
- Rigid aluminum cone for outstanding and natural midrange response
- Particularly clear and dynamic sound characteristics thanks to the rigid and lightweight aluminum cone
- Precisely machined Âneodymium magnet system for highest Âmagnetic flux linearity
- 24-carat gold-plated terminals for maximum conductivity
- Magnet system with threaded hole for hidden fastening from behind
- Sturdy protection grille for protecting the cone from damages
- Aerodynamically optimized basket
- Extremely compact dimensions ideal for installation in the A-pillar – outer diameter almost identical to the BRAX GRAPHIC GL1
