Automotive Active Subwoofer Systems and Drivers

W3-Series 250-Watt Amplified 8-Inch Ported Subwoofer System With MicroSub+™ systems, the power is built right into the subwoofer system. Housing a proprietary Class D amplifier, this incredible subwoofer system utilizes JL Audio's exclusive DCD™ amplifier technology to extract maximum output from its specially engineered, ultra low-impedance W3v3 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 8Wv3 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" embroidery on front baffle. A steel mesh grille is included to protect the subwoofer driver. Construction: CNC-Cut High-Grade MDF Amplifier power: Built-in DCD™ Class D amplifier (250 W @ 0.40 Ω)Nominal Impedance: 0.40 Ω Enclosure and Subwoofer Built in USA with global components.

The PWD-X5’s subwoofer increases the sound system’s overall bass output and when the product is installed under the front seat, it brings the sound stage forward in the vehicle for the best bass and imaging experience. With 165-watts available to the subwoofer and 25-watts x 4 to the speakers, this all-in-one solution lets you create a truly enjoyable and customizable sound experience in just about any in-vehicle cabin space. The PWD-X5 can also be used in non-traditional ways thanks to the Bluetooth® streaming capabilities. In situations where the car radio cannot be replaced, such as in a classic car, music can be streamed to the PWD-X5’s Bluetooth® connection then played through the car’s speakers while utilizing the PWD-X5’s bass and amplified power. If a head unit does not exist, such as on a motorcycle or a side-by-side, the music streamed from a smartphone to the PWD-X5’s Bluetooth® connection is used as the vehicle’s music source.  Specifications 25W x 4 +165W RMS 50W x 4 +240W Peak 4 RCA/Speaker Level Inputs 10-Band Parametric EQ Digital Time Correction Bluetooth Signal Inputs Remote Commander Included OS/Android and Desktop PC Tuning Software 13-13/16” x 9-11/16” x 3-3/16” CES 2019 Innovations Award Winner Alpine PWD-X5 Manual

W3-Series 500-Watt Amplified Dual 8-Inch Ported Subwoofer System With MicroSub+™ systems, the power is built right into the subwoofer system. Housing a proprietary Class D amplifier, this incredible subwoofer system utilizes JL's exclusive DCD™ amplifier technology to extract maximum output from its specially engineered, ultra low-impedance W3v3 drivers. 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 dual 8Wv3 subwoofer drivers, each in its separate airspace. Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure's internal volume relative to its exterior volume. The port for each driver wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The two flared port entries/exits, one on each end of the enclosure, further enhance sound quality by minimizing air-flow noises through each 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).
