1x JL Audio 12TW3-D4: 12-inch (300 mm) Subwoofer Driver Dual 4 Ohm - (12TW3-D4)

JL Audio 12TW3-D4: 12-inch (300 mm) Subwoofer Driver Dual 4 Ω

TW3 12-inch Subwoofer Driver (400 W, dual 4 Ω voice coils)

Building on the core technology of our TW5 thin-line subwoofers, the new TW3’s deliver a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than the W3v3’s.

To allow this remarkable feat to be achieved, JL Audio’s patented thin-line woofer technology compresses the architecture of the TW3’s using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of the large motor structure further forward in the speaker than with conventional designs.

TW3’s are optimized for small enclosures and offer our tab-ear mounting design to maximize cone area within their mounting footprints. We know you’re going to love working with these amazing subwoofer drivers.

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

Patented “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 with Global Components at JL Audio’s Miramar, Florida factory

1x JL Audio XDM300/1 XDM Series Monoblock Class-D Car/Marine Subwoofer Amplifier, 300 W - (XDM300/1)

This little monoblock powerhouse employs our high-speed NexD™ switching design to achieve unprecedented efficiency and amazing power output for its size. It is small enough to fit in most tight space applications, including small boats, pickups, motorcycles and UTV’s (in a weather-tight compartment).

Designed for car or boat installations, the XDM300/1 is built with marine-grade materials and features an exclusive, dual-mode input filter for noise-free performance in boats or cars. Automatic turn-on capability (via signal sensing or DC-offset sensing) is also onboard for easy factory system upgrades.

Targeted specifically for subwoofer applications, the XDM300/1 includes a variable slope low-pass filter with continuously variable cutoff frequency selection from 50-500 Hz. With the addition of an optional HD-RLC or MHD-RLC (water-resistant) remote level controller (each sold separately), the amplifier's level can be adjusted directly from the driver's seat or captain’s chair.

Finished in a sleek, black powder-coat, all controls are protected beneath a gasketed, removable top cover for easy access.

1x JL Audio HD-RLC:Amplifier Remote Level Control and Cable - (HD-RLC)

JL Audio HD-RLC: Amplifier Remote Level Control and Cable

Remote Level Control for Select JL Audio Amplifiers

The HD-RLC remotely controls the Bass Level of the following JL Audio amplifiers:

HD-Series: All models

XD-Series: All models

MHD-Series: All models

M-Series: All models

When the HD-RLC is connected to the above amplifiers, it acts as an attenuator on the input gain of the amplifier and is used to adjust the overall level of the amplifier from the front of the vehicle.

The HD-RLC kit includes the rotary control with a black ABS knob, mounting hardware and one 18 ft. (5.5 m) cable.

A satin-finish aluminum knob can be purchased separately.
