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.
