The Premium Upgrade—tuned to provide the unparalleled sonic accuracy and deep bass impact that you’ll find in recording studio subwoofers, but in a durable, ultra-marine certified design, Polk’s MM1 Mobile Monitor Series subwoofers provide an on-the-go listening experience that’s more powerful than anything you’ll experience from the stock factory set up in your car, boat, motorcycle or ATV.
Ultra-marine certified (IP56 rated)
Dirt & water-resistant & tested for salt-fog, UV & humidity
MM1 Series subwoofers were conceived, designed and engineered to deliver premium audio with thunderous bass, enhanced sonic detail and ultra-durable construction. Dynamic Balance technology, a high excursion bump stack motor structure, glass fiber formers, multilayered and oversized voice coils, high-temp Conex spiders, a vented pole and basket structure, and integrated fuses combine for full-on powerful sound, no matter what vehicle you’re in.
Ultra-Marine Certified
The ultra-durable, MM1 Series Subwoofers have earned their water and dirt resistant IP56 rating through non-corrosive fiberglass reinforced ABS baskets, water-proof surrounds, weep holes for proper drainage and UV-tolerant polypropylene cones. You can count on extra, long-lasting protection—that’s all salt-fog and UV tested so you can bring the bass no matter where life takes you, rain or shine.
Designed To Go The Extra Mile
All Polk loudspeakers rely on our exclusive process to eliminate electro-acoustic and mechanical issues before they become a part of the finished speaker and are also rigorously tested through Polk’s Klippel distortion analyzers. MM1 Series Subwoofers, in addition to offering IP56 waterproof rating and Ultra-Marine Certification, have waterproof Santoprene surrounds that keep the elements out and protect the subwoofer from the harsh effects of boat cleaning agents. They’re designed to keep the music playing that extra mile and beyond.
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.
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.
