Description
JL Audio ACP112LG-TW1
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.
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.
