< p> All GZIW subwoofers have a new updated voice coil, and< br> spirally stiffened IMPP dust cap with 3D structure logo. This significantly affects the resonance of the cone, < br> so the redesigned GZIW guarantees an even tighter kick!< br> < br> 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.< /p>
