B² Audio X2C v2 18"

The B² Audio X2C v2 18" was developed for uncompromising low-bass applications where maximum power handling and extreme sound levels are paramount. The redesigned V2 version utilizes the robust basket from the Elite Series and combines it with a massive 300-mm driver, a 5-inch high-temperature voice coil, and an extremely stable suspension system. The result is a subwoofer that delivers exceptional control, high efficiency, and impressive low-frequency extension—even under enormous sustained loads.

Thanks to its powerful magnet system, enormous linear excursion, and massive moving assembly, the X2C v2 is ideal for high-power demo vehicles, SPL projects, and uncompromising low-bass applications. Even at extreme power levels, the cone remains precisely controlled and delivers deep, powerful bass down to the lowest frequency range. The V2 generation was specifically designed for maximum mechanical stability and reliability and is aimed at users who refuse to compromise.
