Only a few car audio manufacturers in the world use this device. During the long, approximately 10-hour test, the element is put under severe stress. The device monitors the temperatures of all moving parts; sometimes, the power increases up to 4 times the stated power handling. The Klippel optimization device helps to uncover the weak points of the element before production, thus ensuring a thoroughly tested and durable element enters the market.\u003cbr\u003e\n\u003cbr\u003e\nEnclosure recommendation:\u003cbr\u003e\n\u003cbr\u003e\nBass reflex: 24 liters (net)\u003cbr\u003e\nPort: 1 x 70 mm \/ 1 x 2.76″\u003cbr\u003e\nPort length: 28 cm \/ 11.02” \u003cbr\u003e\nTuning frequency: 35 Hz\u003cbr\u003e\n\u003cbr\u003e\nSmall enclosure: \u003cbr\u003e\n \u003cbr\u003e\nBass reflex: 18 liters (net)\u003cbr\u003e\nPort: 1 x 70 mm \/ 1 x 2.76″\u003cbr\u003e\nPort length: 29 cm \/ 11.02” \u003cbr\u003e\nTuning frequency: 40 Hz\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTechnical specifications:\u003c\/strong\u003e\u003cbr\u003eModel\tHigh-Quality SPL Subwoofer\u003cbr\u003e\nDiameter\t30 cm \/ 12″\u003cbr\u003e\nPower handling (RMS)\t450 Watts\u003cbr\u003e\nImpedance\t2x 2 Ohms\u003cbr\u003e\nEfficiency\t84 dB\u003cbr\u003e\nPower recommendation\t200 – 800 Watts\u003cbr\u003e\nVoice coil\t50 mm \/ 2″ copper\u003cbr\u003e\nCone\tPaper sandwich cone\u003cbr\u003e\nMax.
