The 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.

Advanced High-Performance Bass
Every element of the MM1 Series is meticulously engineered for 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.

Ultra-Marine Certified
Featuring an IP56 rating that includes a non-corrosive fiberglass reinforced ABS basket, a water-proof surround, weep holes for proper drainage and a polypropylene cone, you get extra, long-lasting protection-that's all salt-fog and UV tested.

Dynamic Balance Technology
Patented process that guides material selection through rigorous testing that identifies and cancels out unwanted resonant frequencies.
