The Sound Auto Concept Team

25cm MAD S1-104 subwoofer at the best price

MAD subwoofers are designed to be powerful and last for years. These exceptional vibrations drive us to create impressive subwoofers. We want to help you and your vehicle be as powerful as possible. We achieve this through innovative and revolutionary techniques that increase durability.

MOLDED POLYPROPYLENE CONE

We wanted the MAD S1 series to be truly powerful, which required a robust cone. This cone is made of injection-molded polypropylene, resistant to the most severe resonances and membrane ruptures.

DVS™ VENTILATION SYSTEM

If you like it LOUD, good cooling is essential. We equipped the subwoofer with a DVS™ (Dual Ventilation System) to reduce distortion and optimize heat dissipation. Good cooling means less heat, and that reduced heat allows you to add more subwoofers for even bigger sound!

OPTIMIZED CASE

The MAD S1 series is both powerful and impressive. We've created a versatile subwoofer with Thiele/Small settings, ensuring excellent performance in sealed, vented, and bandpass enclosures. Install polyfill on the enclosure to dampen the BOOM and bring out the bass!

CRAZY DESIGN

To complete the subwoofer's high-quality construction, we created a robust, industrial-strength steel basket, MAD-shaped, that's both durable and robust. The 51mm voice coil is made of PCW (pure copper wire), and the dust cover, like the cone, is made of IMPP, for a unique 3D design that will make people jealous and keep critics away! Walk tall and sail proudly!
