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!
