LF Drivers Neo Subwoofer features baskets that have been designed to maximize power handling, excursion, and heat dissipation. The SW series is the next generation of neodymium magnet subwoofers. We focused our energy on long, large diameter voice coils (4” to 6”) for greater power handling and low power compression. In addition, we have developed new suspension systems to offer superb linearity with low DC offset, and excellent durability.
