Hertz DBX30.3 12 inch subwoofer
The DBX 30.3 is a car audio subwoofer box designed to enhance the audio system performance in the low range frequencies, optimising the spaces and ensuring a quick, not too invasive install.
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 makes it an easier fit in most cars.
In other words, it's not huge, but it sounds amazing!
