Amplified Subwoofer System with Dual 8W3v3-0.40 Subwoofers, Built-In 500W 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 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 Subwoofers, 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). 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.

Enclosure and Subwoofers Built in USA with global components.Technology 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. Flared Slot-Port
The flared slot-port design reduces turbulence at the port mouth so as to minimize any audible airflow effects common to ported enclosures. 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. Elevated Frame Cooling (U.S. Patent #6,219,431 & #6,229,902)
JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression. Floating Cone Attach Method - FCAM (U.S. Patent #6,501,844)
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment. Vented Reinforcement Collar
JL Audio's Vented Reinforcement Collar (VRC®) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance. Insert Molded Suspension / Coil / Terminal Sub-Assembly (U.S. Patent #7,379,558)
Spiders, voice coils, terminals and lead wires are preassembled, using a patented process, onto a composite carrier for improved precision and reliability. Customizable Trim Ring
This removable ring can be painted to match the installation theme and directly receives JL Audio grille mesh inserts (sold separately). 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. 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.
