2x JL Audio 12TW3-D8 12-inch thin-line subwoofer driver (400W, dual 8 ohm voice coils) (12TW3-D8)
JL Audio 12TW3-D8
TW3 12-inch Subwoofer Driver (400 W, dual 8 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)

- DMA-optimized motor designs
- Patented “concentric tube” architecture
- Patented “floating cone attach method” technology
- Cast alloy frame
- Injection molded, mica-filled polypropylene cone

1x JL Audio RD1000/1 1000W Class D Monoblock Subwoofer Amplifier (RD1000/1)
RD1000/1
Monoblock Class D Subwoofer Amplifier, 1000 W x 1 @ 2 Ω / 600 W x 1 @ 4 Ω - 14.4V
Purpose-built for subwoofer applications, the RD1000/1 monoblock amplifier delivers 1000 watts of jaw-dropping bass output into 2 ohms (14.4V, 1% THD). At the heart of this ultra-sleek and compact power plant is JL Audio’s exclusive NexD™ Class D technology, permitting high power output with exceptional efficiency and low distortion.
For your convenience, all of the RD1000/1’s controls are located on top of the amplifier, beneath a protective cover, with all connections found along one side of its chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balance inputs are also onboard, capable of accepting most input voltage levels. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.
The RD1000/1 is also equipped with an onboard LED-clipping indicator. This all-new, innovative feature lets you easily set your amplifier’s input sensitivity setting, quickly and accurately, with no special equipment needed. The RD1000/1 features a durable, black powder-coated finish and a top-mounted, dual-color LED light strip that reports the overall status and condition. Control of the subwoofer level from the driver’s seat is easily accomplished with the addition of the optional RBC-1 remote level control (sold separately).
