Premium Upgrade

 

Tuned for the total sonic accuracy you get in a studio subwoofer, the MM1 Series reconfigures this kind of high-quality deep bass impact for an on-the-go listening experience that totally outperforms your OEM factory setup.

 

Ultra Marine Certified

 

Featuring an IP56 rating that’s dirt- and water-resistant it includes a non-corrosive fiberglass reinforced ABS basket, a water-proof surround, weep holes for proper drainage and a composite cone for extra, long-lasting protection against the elements—all of it salt-fog and UV tested.

 

Waterproof Santoprene Surround & Fiberglass Basket

 

This attractive high performance material maximizes throw with its ultra-flexible, ultra-durable properties—and prevents the elements from entering the speaker unit. Plus, it combats the harsh effects of boat cleaning agents. 

Offers heavy-duty protection for back half of the speaker, which helps prevent corrosion and general wear and tear.
