For years, our BRAX subwoofer has been the benchmark for precision and unconditionally controlled bass reproduction. It was even more demanding to create a BRAX subwoofer that uncompromisingly reproduces deep bass even in the smallest possible enclosures. Each component of this exceptional driver is not only made for dynamics and perfect tonality but is also designed to convert even huge loads of amplifier power into sound pressure without compression.
