X-Series v.3 18" Subwoofer

2500 Watts RMS / 5000 Watts Peak Dual 1 or 2 ohm voice coil Made for extremely deep bass Triple-stacked magnet 3” voice coil Hyper-extended pole Built to order Designed with an extended pole piece and an incredible four inches of peak-to-peak excursion, the X v.3 is engineered for ultra-deep bass and high power handling. Engineered to set a new standard in the low-frequency/small-ported-box subwoofer category, the X Series can also work in up to a 50% larger enclosure if you desire even more low-end extension. The X v.3 series differentiates itself with its incredibly linear suspension, ensuring the lowest level of bass extension in a small enclosure while maintaining extremely low levels of distortion. Notably, the v.3 series features a much larger motor structure (220mm vs. 190mm on the v.1 series), improved motor ventilation, and an all-new Mega-Roll v.2 surround, providing a more linear and rugged update to the world-famous Mega-Roll v.1 surround design.
