Don´t get fooled by the affordable price! These budget class XSPL-monsters are designed with Klippel-optimization to squeeze out every single desibel that is possible to get. Voice coil cooling is very efficient and long excursion gives you a LOT of bass. Very linear impedance curve makes it possible to really extract all the power from the amp to these subwoofers.
