Powerful, Durable Subwoofer

It comes aboard as an easy-to install free-air application, equipped with high quality that even extends to the gold-plated and 2-way spade/insert terminals.

Ready for a splashy, sunny cruise

Due to their ATSM proven Salt/Fog and UV Marine specification and their NEMA rated water resistance on level 5 all Alpine Marine Speakers exceedingly resist the challenges of the marine environment.

Perfect Amp-Speaker Matching

All three Marine Speakers are engineered to work with the PDX Marine Amplifiers for optimum system building capability. Their perfectly aligned audio characteristics provide the highest possible sound quality.

Designed for Clean Installation with Maximum Water Resistance

Hidden-screw grille design and supplied waterproof rubber mounting gasket allow for clean and leak-free installation. All parts – including the speaker connections – are saltwater corrosion resistant. The SWR-M100 is also equipped with magnetic shielding to avoid interference from other marine electronic devices, which allows its installation anywhere on the boat.

High-Strength Frames

All models have high-strength polypropylene frames resisting UV-light and corrosion while keeping the motor structure aligned for maximum output. Moreover they are tough enough to handle higher levels of vibration on the boat.
