JL Audio 12TW1-4 Thin-Line 12-inch 4-ohm Subwoofer Driver$299.99
The 12TW1-4 is the 4 Ohm version of its 12" subwoofer model and falls under JL Audio's TW1 series line that matches the JL Audio W1 line's construction with a Mica-filled polypropylene cone and a rubber surround. However, the TW1 lineup increases functionality over the W1 line with its powerful combination of a shallowing mounting depth and excursion capability, while operating in insanely small enclosures.
The 12TW1-4 model comes in a single, 4 Ohm voice coil. We recommend powering the 12TW1-4 with a 750 watt JL Audio amplifier. If you are only running 1 subwoofer, be sure to look at the amplifier output at 4 ohms, not just the number that the amp is rated at when completing your setup.
The 12TW1-4 12" subwoofer is optimized to operate in a compact 0.650 cubic feet (18.41 liter) sealed enclosure, or a 1.125 cubic feet (31.86 liter) ported enclosure.
