Description

JL Audio ACP208LG-W3v3 Dual 8W3v3 Powered MicroSub+™ with DCD™ Amplifier

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.

*DCD™ Amplifier Technology

Summary: The most efficient subwoofer amplifier technology on the market delivers impressive power with minimal current draw and heat.

Detailed Information: The conventional way to get high power in a car amplifier is to use a switching power supply. This increases the battery voltage from its nominal 12V to something higher–the more powerful the amplifier, the greater the required voltage. This power conversion is never perfectly efficient–about 10% of what goes into the amplifier is wasted and ends up dissipating into heat.

JL Audio's Direct Conversion Class-D Technology (DCD™) innovates by eliminating the need for this power conversion step entirely. Because we are still bound by the laws of physics, the lack of a step-up power supply means we have to extract as much power as possible from the vehicle's 12V supply. If we were to connect a DCD™ amplifier to a conventional 4-ohm subwoofer with this limitation in place, we would only achieve about 25 watts, and we all know that powering a subwoofer requires a lot more power than this.

To overcome this obstacle, the DCD™ amplifiers have been designed to drive extremely low impedance speaker loads–as low as 1/4-ohm (0.25 ohm)! With these very low impedance loads, we can deliver up to 500 watts of clean power, subwoofer power. Those who know Ohm's law and that nothing is free realize that this will require a lot of current to flow, and that's exactly what DCD™ is engineered to deliver...over 50 Amps peak into a speaker!

To deal with these high current amounts, the special, very low-impedance JL Audio Subwoofers used with DCD™ amplifiers are engineered with unique voice coils and tinsel leads. Connections between the amplifier and speaker are made using special heavy gauge speaker cable, with special attention paid to connection integrity to deal with the high current output.

The benefit of all this effort is that DCD™ amplifiers completely avoid the losses associated with a switching power supply, allowing the entire amplifier to achieve total power efficiencies in the 91-94% range. This is very close to the theoretical limit for Class-D efficiency and results in very little heat being generated. All of this allows for a very compact, powerful amplifier that can fit in some of our most space-efficient enclosed systems.
