Alpine S-W12D2 S-Series 12' Dual 2-Ohm Subwoofer

The new S-Series subwoofers use a new design that’s almost 1-inch shallower than their predecessors.
High-excursion underhung voice coil configuration.
65mm voice coil with high-temp 5-layer dvc winding on aluminum former.
Reinforced parabolic cone structure with pulp/Kevlar con & PP/Mica/Talc Dustcap.

4000 W continuous program power capacity153 mm (6 in) split winding copper voice coil30 - 1000 Hz response96 dB sensitivity60 mm peak-to-peak excursion before damage.
Neodymium magnet allows a very high force factor and linear excursion Double silicone spider with optimized compliance Ventilated voice coil gap for reduced power.
compression Aluminum demodulating ring for very low distortion.

Variable pitch winding delivers ultra-low resistance, a powerful spark and outstanding EMI/RFI noise suppression.
Numbered for easy cylinder identification and coil wires are color coded for correct and easy installation.
Positive-locking, corrosion-resistant stainless steel terminal ends for tight fit and maximum resistance to vibration and separation.
High-temp (250°+ C / 482°+ F) silicone outer jacket resists moisture, oil/petrol and cracking due to temperature extremes.
