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.

JL Audio – 10W1V3-2 10-inch Subwoofer Driver, 2 ohm
W1v3 10-inch Subwoofer (300 W, 2 ohm)
The 10W1v3 is an outstanding choice when space is very tight and amplifier power is moderate. It features shallow mounting depth (4.6 in. / 117 mm) and a compact motor structure, allowing it to comfortably fit in a lot of spaces where a typical 10-inch driver will not. Lacking a pole vent, the rear of the motor structure can be placed directly against an enclosure boundary. Excellent excursion capability and linearity allow it to reproduce sub-bass with shocking extension and quality. Several of JL Audio’s proprietary technologies enhance its performance and reliability.
The 10W1v3-2 is best used with amplifier power in the 75W – 300W range and is optimized to operate in a compact 0.55 cu. ft. (15.57 l) sealed enclosure.

JL Audio – 10TW1-4 10-inch Subwoofer Driver, 4 ohm
TW1 10-inch Subwoofer (300 W, 4 ohm)
Built on JL Audio’s patented thin-line subwoofer technology, the 10TW1 delivers a powerful combination of shallow mounting depth and excursion capability, while operating in insanely small enclosures (0.35 cu.ft. / 10 liters). This, combined with a special cast alloy frame design, makes the 10TW1 capable of operating in extremely tight spaces. These include under-seat installations in trucks, 2-seat sports cars and many other creative applications requiring a compact, low profile subwoofer design.
JL Audio’s patented thin-line woofer technology compresses the architecture of the 10TW1 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 a large motor structure further forward in the speaker than with conventional designs.
The 10TW1 also features a clever frame design that minimizes the frontal clearance required for the excursion of the driver. This is accomplished by recessing the suspension attachment surface, so that most of the forward excursion occurs within the frame’s dimensions. Thanks to this feature, the 10TW1 requires only 0.87 inches (22 mm) of frontal clearance, even with its grille installed. This allows for more efficient use of space and increased enclosure volume within a given overall depth.
Even though the 10TW1 is optimized for an enclosure much smaller than any other JL Audio ten-inch Subwoofer, it never sounds like a big woofer struggling in a tiny box…instead, it delivers all the rich, deep, controlled bass you have come to expect from a JL Audio subwoofer system.
– Very shallow mounting depth (4.36 in / 111 mm)
– No pole vent: permits mounting close to rear wall of enclosure
– Extremely small sealed enclosure volume requirements
– Long linear excursion capability (0.40 in / 10 mm, one-way)
– DMA-optimized motor design
– Patented “concentric tube” architecture
– Patented “floating cone attach method” technology
– Cast alloy frame with flat edges for tight driver grouping
– Injection molded, mica-filled polypropylene cone
– Rubber surround
– Steel mesh grille included with each driverSKU: JL AUDIO - 10TW1-4 - Car Subwoofers & enclosures
JL Audio – 10W7AE-3 10-inch Subwoofer Driver, 3 ohm
10th Anniversary Edition – W7 10-inch Subwoofer (750 W, 3 ohm)
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
– Anniversary Edition Terminal LabelSKU: JL AUDIO - 10W7AE-3 - Car Subwoofers & enclosures
JL Audio – 8W3V3-4 8-inch Subwoofer Driver, 4 ohm
If you need an 8-inch subwoofer that can create outstanding bass in extremely small enclosures, the 8W3v3 will do the job and surprise you with its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.375 in. (10 mm) of controlled, one-way, linear excursion.
The 8W3v3-4 is best used with amplifier power in the 75W – 250W range and is optimized to operate in a tiny 0.30 cu. ft. (8.5 l) sealed enclosure, or a 0.35 cu. ft. (9.9 l) ported enclosure.
