JL Audio ACS112LG-TW1, Loaded Single 12" TW1 Series MicroSub+ with DCD Amplifier, Sealed, 400W
In PowerWedge+™ systems, the power is built right into the subwoofer system. Housing a proprietary Class D amplifier, this subwoofer system employs 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.
Harnessing the performance and insanely small box requirements of the TW1 Subwoofer, this subwoofer system is designed to deliver amazing sub-bass from an enclosure that is only 5 inches (127 mm) deep. Its low-profile enclosure design has been carefully engineered to the optimum sealed enclosure alignment for the 10TW1 driver and has been fine-tuned through extensive real-world listening.
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.
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.
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.
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.
Tab-Ear Frame Design
This frame design feature facilitates mounting the Subwoofer in tight spaces.
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
Our Concentric Tube Suspension™ technology delivers unprecedented excursion in a low-profile woofer.
Built in U.S.A. with Global Components
JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
