Sundown Audio M12 2000W Subwoofer

Description The M-series is really a different kind of woofer due to its incredibly linear suspension. They are designed for the LOWEST level of bass extension possible in a small enclosure while maintaining extremely low levels of distortion. This is all thanks to the Sundown Mega-Roll surround & proprietary Sundown PG linear suspension (fully computer optimized). As with most subwoofers from Sundown the M-series features a magnet inner-diameter aluminum shorting ring for superior inductive distortion performance as well. 2000 Watts RMS / 4000 Watts Peak Mega Roll Surround and Frame Etched All Black Backplate Quad Stack Magnet Structure   Specifications RE (Ohms) 2.22 4.0669 FS (Hz) 31.931 32.714 VAS (L) 39.313 15.06 Qes 0.696 0.686 Qms 4.654 4.768 Qts 0.606 0.6 Le (mH) 1.946 3.641 BL (NA) 17.484 23.84 Mms (Grams) 477.932 466.6312 Cms (uM/N) 51.979 50.725 Sens (dB @ 1w/1m) 84.387 80.6 Xmax 35mm 35mm T/S SPECS M12D1 M12D2 Enclosure Specifications Sealed Enclosure Not Recommended Ported Enclosure 2.5 cu ft Recommended Tuning 32Hz Recommended Port Area 40 sq in 4th Order Sealed Side 1.0 cu ft 4th Order Ported Side 3.0 cu ft 4th Order Port Area 60 sq in 4th Order Port Length 8″ Displacement 0.21 cu ft Depth 10.88″ Outside Diameter 12.67″ Cut-Out 11.09″
