Active MicroSub System with Single 8W3v3-4 Driver and DCD Amplifier

Active MicroSub System with Single 8W3v3-4 Driver and DCD Amplifier

£659.99

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 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 enclosures 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 drivers 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.
Finish: Black, high-grade automotive carpet with silver “JL AUDIO Built In USA” 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 Ohm)
Nominal Impedance: 0.40 Ohm
Enclosure and Subwoofer Made in USA
External Width (W) 18.5 in / 470 mm
External Height (H) 11.125 in / 283 mm
External Depth (D1) 5.125 in / 130 mm
Net Weight 19.9 lb / 9.03 kg
