Automotive Passive Subwoofer Systems and Drivers

EVL Series 6-1/2-Inch 200-Watt Subwoofer Driver, 2-Ohm or 4-Ohm Dual Voice Coil The Skar Audio EVL-65 D2 subwoofer was designed to be the most responsive, powerful, and efficient 6.5 inch subwoofer on the market. Don't be fooled by the size, the EVL-65 is one monster of a subwoofer, featuring a 4-layer 2" pure copper voice coil, and a powerful 39 Oz single slug ferrite motor. The small size of this driver allows it to be very versatile, as it can be used in a variety of applications where adding a woofer might not otherwise be possible. Conservatively rated at 200 watts RMS Power, and 400 watts max power, the EVL-65 features an aluminum diecast chassis which utilizes an advanced air flow cooling system to help dissipate heat. The suspension design of this subwoofer is highlighted by its unique yellow spider - which connects to the coil former with premium stitched lead wires. All of these incredible features make the EVL-65 the obvious choice when looking for a versatile 6.5-inch car subwoofer.

TW3-Series 12-Inch 400-Watt Thin Subwoofer Driver, 4-Ohm or 8-Ohm DVC The 12" TW3 thin subwoofer driver by JL Audio offers a shallow mounting depth with an excursion capability that is remarkably capable of greater excursion than JL's W3v3 full size subwoofers. JL Audio’s TW3 sub utilizes a patented thin-line woofer technology that compresses the architecture of the 12TW3 woofer using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and spider, while allowing the placement of the large motor structure to be moved further forward on the chassis than with conventional designs. JL Audio 12TW3-D4 and 12TW4-D8 are optimized for small enclosures and offers JL's tab-ear mounting design to maximize cone area within their mounting footprints. Deep, powerful and accurate JL Audio bass is now possible in more applications than ever. Very shallow mounting depth (3.25 / 3.50 Inches) No pole vent: permits mounting close to rear wall of enclosure. Very small sealed enclosure volume requirements Very long linear excursion capability (0.60 In / 15.2 mm, one-way) DMA-optimized motor designs “concentric tube” architecture Patented “floating cone attach method” technology Cast alloy frame Injection molded, mica-filled polypropylene cone Rubber surround Aluminum-alloy dust cap and rear cap with JL Audio logo Precision-built in USA at JL Audio’s Miramar, Florida factory with global components General Specifications Continuous Power Handling 400W RMS Recommended Amplifier Power 200W - 400W RMS Nominal Impedance Dual 4Ω/8Ω JL Audio 12TW3 Manual
