Active subwoofer JL Audio ACS112LG-TW1
Active system with one 12TW1-0.25 subwoofer and built-in 400W RMS class D amplifier in a closed enclosure. In PowerWedge+™ systems, the power supply is built right into the subwoofer system. Class D self-amplified subwoofer system uses exclusive DCD™ amplifier technology to extract maximum performance from the specially designed 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, allowing them to generate remarkable power with unprecedented efficiency. This subwoofer system is designed to deliver amazing bass from a cabinet that is only 168mm deep. Its low-profile design has been carefully designed and tuned directly for the JL Audio 12TW1 subwoofer for optimal sound quality and high performance. Integration with OEM and aftermarket head units is a breeze thanks to a variety of input options and auto-on capability (via signal sensing or DC offset sensing). Also included is a variable frequency low pass (50-200 Hz) along with a switch to control the output polarity. Adding the optional RBC-1 Remote Level Control (sold separately) lets you control subwoofer levels right from the driver's seat. A quick-disconnect power connector makes it easy to remove the subwoofer when you need more space.

| RMS power of the subwooferThe RMS power of an active subwoofer is the constant power that the active subwoofer can play over a long period of time. We recommend following this value. The RMS power of active subwoofers is taken as the RMS power of the integrated amplifier, which in most cases is slightly undersized, which guarantees protection against subwoofer burning. | 400 W |
| Energy class of the amplifierAmplifiers are divided into two basic classes: analog and digital . Analog amplifiers (A/B) have higher consumption requirements, but usually have a more natural sound. Digital amplifiers (D) have significantly lower consumption and higher efficiency, but the sound may not be as faithful as with classic analog amplifiers. | D |
| The diameter of the subwoofer usedThe diameter of the subwoofer that is installed in the active box. | 300 mm |
| Low-pass filter (LPF) | 50 - 200 Hz |
| High level inputThe high-level input on the active subwoofer enables connection directly to the speakers in the car without purchasing an external high/low converter. Use in the case of mounting an active subwoofer on the original car radio. | Yes |
| Automatic on and offThis function will facilitate your installation and solve the problem of finding a remote signal, which is sometimes a problem with original car radios. The active subwoofer with the Auto sense function can recognize that the equipment in the car is active and turn itself on. A useful and practical feature. | Yes |
| Remote control included in the packageSome models of active subwoofers also have wired remote controls in the package, which on the one hand connect to the active box, and on the other hand you have a potentiometer that you can place anywhere in the cabin. A common place to place the remote control is under the steering wheel. The advantage is the regulation of power, and therefore volume, depending on driving conditions and the mood of the crew in the car. | No |
| Option to purchase a remote controlIf the active subwoofer has a remote control input. | Yes |
| Protective gridProtective grids or bars, as protection against mechanical damage to the subwoofer. | Yes |
