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

With MicroSub ™ systems, the power is built right into the subwoofer system. Housing a proprietary Class D amplifier, this incredible subwoofer system utilizes 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.

Key to the enclosure's performance is its efficient slot-ported design and precise tuning of its 12TW1 subwoofer driver. Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure's internal volume relative to its exterior volume. The port wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The flared port entry and exit further enhance sound quality by minimizing air-flow noises through the port.

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. As with all MicroSub™ systems, these amplified versions produce the kind of output and extension normally associated with much larger systems.

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 Built In USA" embroidery on front baffle. A steel mesh grille is included to protect the subwoofer driver.

Construction: CNC-Cut High-Grade MDF

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

Technology
DCD™ Amplifier Technology

The most efficient subwoofer amplifier technology on the market delivers impressive power with minimal current draw and heat.

V-Groove MDF Construction

This advanced cabinet-building technique uses CNC-machining to create precise panel joints that make enclosure assembly more efficient and exact.

Flared Slot-Port

The flared slot-port design reduces turbulence at the port mouth so as to minimize any audible airflow effects common to ported enclosures.

Dynamic Motor Analysis - DMA Optimized Motor

JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

Engineered Lead-Wire System (U.S. Patent #7,356,157)

Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.

Concentric Tube Suspension (U.S. Patent #5,734,132 & #6,095,280)

Our patented Concentric Tube Suspension™ technology delivers unprecedented excursion in a low-profile woofer.

Tab-Ear Frame Design

This frame design feature facilitates mounting the subwoofer driver in tight spaces.

Precision Built in U.S.A.

JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
