This affects the resonance of the cone considerably,  \u003cbr\u003eso the renewed GZIW guarantees an even tighter kick!\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e Don't let the low price fool you. This element is excellent in terms of performance for its price. More design work has been done than on most manufacturers' higher price ranges. Klippel optimization involves 10 hours of testing, where the element's behavior is measured in many ways and weak points are dug out before production. This results in a very high-performance element.\u003cbr\u003e\u003cbr\u003e Thanks to the flat impedance response, the element accepts power well. Thanks to the carefully designed voice coil and its cooling, power endurance is excellent. The long travel allows for ample sound pressure levels even at lower frequencies.\u003cbr\u003e\u003cbr\u003e \u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e Diameter\u003cbr\u003e 30cm \/ 12″\u003cbr\u003e Power Handling (RMS)\u003cbr\u003e 350 Watts\u003cbr\u003e Impedance\u003cbr\u003e 4 Ohm\u003cbr\u003e Efficiency\u003cbr\u003e 88 dB\u003cbr\u003e Power Recommendation\u003cbr\u003e 200 – 400 Watts\u003cbr\u003e Voice Coil\u003cbr\u003e 50 mm \/ 2″ copper\u003cbr\u003e Membrane Layout\u003cbr\u003e HQPP cone with 3D structure\u003cbr\u003e Max.
