GAS Audio MAD PB1-48

With the GAS Audio MAD PB1-48, you get a fully assembled sound reinforcement system designed for maximum volume and high efficiency. The combination of four powerful 8-inch midrange drivers and two horn tweeters delivers tremendous sound pressure, excellent speech intelligibility, and dynamic sound reproduction—ideal for SPL cars, show cars, or anyone who doesn’t want to compromise on impressive sound—even with the doors open. 

The rugged MDF enclosure with an aerodynamically optimized slot port promotes clean airflow and reduces distracting airflow noise even at high volume levels. Thanks to the integrated AST (Active Smart Terminal), the system can be converted to active mode as needed, allowing the midrange and treble to be amplified separately. This opens up additional possibilities for sound tuning and further enhances performance.

The built-in midrange drivers feature reinforced paper cones, sturdy steel baskets, and powerful ferrite magnets, delivering high power handling and a dynamic midrange. They are complemented by two horn tweeters with aluminum diaphragms, which ensure precise high-frequency reproduction even at high volume levels. The result is a powerful and stable sound specifically designed for SPL applications.
