Product Description

JL Audio ACP112LG-TW1 #93333 MicroSub+ single 12″ powered subwoofer enclosure

With JL Audio ACP112LG-TW1 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.
