Hertz DBX 30.3


The DBX 30.3 is a car audio subwoofer box designed to enhance the audio system performance in the low range frequencies, optimizing the spaces and ensuring a quick, not too invasive installation.
The subwoofer unit, which is the DS sub, provides a punching, dynamic, surrounding bass. The very thick MDF enclosure, thanks to its rigid and stable structure, doesn’t affect the acoustics. The rear slanted panel fulfils two important functions: it reduces back-wave reflections and eases the installation.
