Unique design of this 21” monster can serve as a model of the embodiment of the latest SPL technology to achieve extreme sound pressure level and reliability in extreme subwoofer usage modes. A highly efficient subwoofer motor based on the highest-grade neodymium rings, combined into a single array of magnetic circuits made of low carbon steel, together with the huge cone area, allowed to achieve unreachable sensitivity for subwoofers of 91dB. Efficient design with optimal ratio of power and the moving parts parameters of the subwoofer, with use of 5” voice coil wounded with maximum cross section size aluminum wire, provides a huge linear displacement and incredible handling abilities of the subwoofer.
