Polk Audio MM1 Series Coaxial Marine Speakers — 5x7 Inch, 300W

Engineered for marine environments, the Polk Audio MM1 Series 5x7 Inch 300W coaxial speakers deliver studio-quality sound with rugged, saltwater-ready construction. The design uses a fiberglass reinforced ABS basket and epoxy coated crossovers for long-term durability, while waterproof inner and outer surrounds with weep holes ensure proper drainage. Titanium plated cones provide reliable, moisture-resistant performance and the Dynamic Balance technology suppresses distortion and unwanted resonances for clear, full sound. These oval speakers combine a 5 x 7 inch dynamic balance driver midwoofer with a low-protrusion pivoting 1 inch terylene tweeter and an additional 1 inch round tweeter to reproduce detailed highs and robust mids. The system is tuned for wideband response and precise imaging to give a premium audio upgrade and accurate sonic performance on boats and other wet-location installs.
