The test periods last 10 hours and during them the element's power endurance is exceeded fourfold and its behavior is studied with numerous different measurements. This allows us to eliminate weak points already in the design phase and the end result is an element without weaknesses!\n\u003cbr\u003e\n \u003cbr\u003eThe large and powerful magnet keeps the three-inch voice coil under control perfectly. The sturdy cast body is designed so that it breathes properly and does not hinder the bass in the cabinet. Thanks to the long voice coil and deep magnet, the driver has a travel range of 70 millimeters! This long travel range creates amazing bass reproduction at all frequencies, even the lowest ones. The driver's reinforced paper cone is really stiff and the stitch-reinforced attachment to the top suspension is guaranteed to last.\u003cbr\u003e\u003cbr\u003e \u003cb\u003eSpecifications:\u003c\/b\u003e\u003cbr\u003e Diameter\u003cbr\u003e 30cm \/ 12″\u003cbr\u003e\u003cbr\u003e Power Handling (RMS\/SPL.)\u003cbr\u003e 3000 \/ 6000 Watts\u003cbr\u003e\u003cbr\u003e Impedance\u003cbr\u003e 2x 1 Ohm\u003cbr\u003e\u003cbr\u003e Efficiency\u003cbr\u003e 87.5 dB\u003cbr\u003e\u003cbr\u003e Power Recommendation\u003cbr\u003e 2000 – 6000 Watts\u003cbr\u003e\u003cbr\u003e Voice Coil\u003cbr\u003e 75 mm \/ 3″ CCA\u003cbr\u003e\u003cbr\u003e Membrane Layout\u003cbr\u003e Reinforced paper\u003cbr\u003e\u003cbr\u003e Max.
