ACS112LG-TW1

Single 12TW1 PowerWedge+™ with DCD™ Amplifier, Sealed, 0.25 Ω

Amplified Subwoofer System with Single 12TW1-0.25 Subwoofer, Built-In 400W Class D Amplifier, Black Carpet - Sealed Enclosure





In PowerWedge+™ systems, the power is built right into the subwoofer system. Housing a proprietary Class D amplifier, this subwoofer system employs our exclusive DCD™ amplifier technology to extract maximum output from its specially engineered, ultra low-impedance TW1 driver. By combining direct power conversion with an ultra-high current output section, DCD™ amplifiers are free of conventional switching power supplies, enabling them to generate remarkable power with unprecedented efficiency.

Harnessing the performance and insanely small box requirements of the TW1 Subwoofer, this subwoofer system is designed to deliver amazing sub-bass from an enclosure that is only 6.625 in. (168 mm) deep. Its low-profile enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 12TW1 driver and has been fine-tuned through extensive real-world listening.

Integration to OEM and aftermarket head units is a snap thanks to a variety of input options and automatic turn-on capability (via signal sensing or DC offset sensing). Also included is a variable frequency low-pass filter (50-200 Hz), along with output polarity control switch. Adding an optional RBC-1 remote level control (sold separately) lets you control subwoofer levels directly from the driver’s seat. A quick-disconnect power connector makes it easy to remove the subwoofer when you need the extra space.

Note: DCD™ amplified systems use very specific components. Never use a DCD™ amplifier or its companion subwoofer(s) with incompatible, non-DCD™ products. Doing so will void the warranty and may cause severe damage.

Finish: Black, high-grade automotive carpet with silver "JL AUDIO" embroidery on front baffle. A steel mesh grille is included to protect the Subwoofer.

Construction: CNC-Cut High-Grade MDF

Amplifier power: Built-in DCD™ Class D amplifier (400 W @ 0.25 Ω)

Nominal Impedance: 0.25 Ω

Enclosure and Subwoofer built in USA with global components

Benjamin ★★★★★

Got it hooked up in my truck and the built-in 400W amp saves so much space compared to my old separate setup. The bass is tight and punchy, easily fills the cab without any distortion. Exactly what I needed for clean, low-end sound.

Carter M. ★★★★★

The sealed enclosure makes this hit incredibly tight and clean, even with the gain barely at noon. I’ve been listening to electronic and hip-hop all week, and that 400w DCD amplifier delivers every kick drum with authority.

Benjamin J. ★★★★★

I didn’t expect such a compact subwoofer to hit this hard in my truck’s cab, and the sealed enclosure keeps the bass tight without any rattling. The built-in 400W amp makes installation a breeze, just run power and ground and you’re set.
