JL Audio ACP112LG-TW1 MicroSub+ powered subwoofer with 12″ sub and 400-watt amp
$899.99
Amplified Subwoofer System with Single 12TW1-0.25 Subwoofer, 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. 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” embroidery on front baffle. A steel mesh grille is included to protect the Subwoofer.

0 out of 5(0)W0v3 15-inch Subwoofer (500 W, 4 ohm)
Sometimes, bigger is better… For these situations, the 15W0v3 offers excellent excursion capability, linearity and an overall performance envelope that puts it right at the top of its price class. It features a very beefy 2.5 in. diameter voice coil and our Elevated Frame Cooling design for enhanced power handling and reliability.
The 15W0v3 is best used with amplifier power in the 150W – 500W range and is optimized to operate in a moderately sized 1.875 cu. ft. (53.1 l) sealed enclosure, or a 2.75 cu. ft. (77.88 l) ported enclosure.

0 out of 5(0)TW5v2 13.5-inch Subwoofer (600 W, 4 ohm)
We couldn’t leave the ultimate thin woofer alone… we had to make it even better.
Our patented thin-line woofer technology compresses the architecture of the 13TW5v2 using a concentric tube structure that supports the 7-inch diameter voice coil and the suspension attachments. This permits placement of the large motor structure much further forward in the speaker than with conventional designs, while allowing excellent linear excursion capability and mechanical stability.
To unleash even more performance from this technology, the v2 improves upon the original 13TW5 with 13% greater linear excursion capability. The cast alloy chassis has also been modified for greater strength and the redesigned motor now features an annular vent. The v2 is also available in single 2 ohm and single 4 ohm voice coil versions to fit a wide range of applications.
In keeping with its ?tight-spaces? mission, the 13TW5v2 is optimized for enclosures that are far smaller than most 12-inch woofers require and only a bit larger than the air space needs of a typical, small-box 10-inch woofer. The mounting system is designed to fit in about the same footprint as a typical 12-inch woofer.
The 13TW5v2 is best used with amplifier power in the 250W – 600W range and is optimized to operate in a 0.80 cu. ft. (22.7 l) sealed enclosure.
Never has such high-quality sub-bass been possible in the most challenging installation applications.

If you are seeking reference-grade sub-bass from a 10-inch driver, your search ends here. Total Car Audio in the UK called it like this when they reviewed the 10W7: “This gives an all round performance of such high quality on every level, that bettering it will be very hard to achieve.” Not only does the 10W7 deliver amazing excursion capability for its size, but it also maintains complete composure under power and is able to track complex bass material with uncanny accuracy and power.
The 10W7AE is best used with amplifier power in the 300W – 750W range and is optimized to operate in a 1.25 cu. ft. (35.4 l) sealed enclosure, or a 1.5 cu. ft. (42.5 l) ported enclosure.
W7AE (Anniversary Edition) Subwoofers celebrate the 10th Anniversary of the launch of the W7 subwoofers. Functionally, they are identical to the original W7’s, but they are distinguished by the following cosmetic differences:
– Satin-Black Powdercoated Baskets
– Bright Anodized Surround Clamp Ring
– Anniversary Edition Cone Badge
