JL Audio 12TW3-D4 Thin-Line 12-inch Dual 4-ohm Voice Coils Subwoofer Driver$379.99
The 12TW3-4 is the dual 4 Ohm version of JL Audio's 12" subwoofer model and falls under the TW3 series that lines up similarly against the JL Audio W3 series, but features construction with a Mica-filled IMPP cone and a rubber surround. However, the TW3 lineup increases functionality over the W3 line with its powerful combination of a shallowing mounting depth and its need for minimum airspace, allowing it to operate in insanely small enclosures.
The other area the 12TW3-4 model differs from the W3 line is that 12TW3-4 model comes in a dual, 4 Ohm voice coil instead of the TW3's single coil making it a perfect match to be supported by a mono amplifier. We recommend powering the 12TW3-4 with a 500 watt JL Audio amplifier. If you are only running 1 subwoofer, be sure to look at the amplifier output at 2 ohms.
The 12TW3-4 12" subwoofer is optimized to operate in a compact 0.8 cubic feet (22.65 liter) sealed enclosure, or a 0.95 cubic feet (26.90 liter) ported enclosure.
