This significantly affects the resonance of the cone, so the redesigned GZIW guarantees an even tighter kick! 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.\n\t\t\t\t\t\u003c\/div\u003e\n\u003cbr\u003e\u003cbr\u003e\u003cdiv\u003e\n\t\t\t\t\t\t\t\n\t\t\t\t\t\t\t\tDiameter\u003cbr\u003e\n25 cm \/ 10″\u003cbr\u003e\n\u003cbr\u003e\nPower Handling (RMS)\u003cbr\u003e\n250 Watts\u003cbr\u003e\n\u003cbr\u003e\nImpedance\u003cbr\u003e\n4 Ohms\u003cbr\u003e\n\u003cbr\u003e\nEfficiency\u003cbr\u003e\n87 dB\u003cbr\u003e\n\u003cbr\u003e\nPower Recommendation\u003cbr\u003e\n200 – 300 Watts\u003cbr\u003e\n\u003cbr\u003e\nVoice Coil\u003cbr\u003e\n50 mm \/ 2″ copper\u003cbr\u003e\n\u003cbr\u003e\nMembran\u003cbr\u003e\nHQPP cone with 3D-structure\u003cbr\u003e\n\u003cbr\u003e\nMax.
