JL Audio H.O. Wedge ported enclosure — single 12W3v3-2, 2 ohm

JL Audio's patented High Output Enclosures are engineered to deliver a combination of strong output and sound quality that is rare in ready-made enclosures.

The patented chamber-coupled port design (U.S. patent #6,625,292) wraps around the inner enclosure boundary and terminates on one side of the woofer, coupling the port output directly to the woofer's output. This layout provides the surface area and port length needed to maximise performance from the 12W3v3-2 driver.

The enclosure has been tuned to the optimum ported alignment for the 12W3v3 through extensive real-world listening. The system performs well with as little as 150W of amplifier power, but is at its best with 300–500W.

The unit ships wired, loaded and ready to connect via a five-way binding post terminal. The angled-back wedge profile sits tightly against a vehicle's rear seat, keeping boot space loss to a minimum.

About the JL Audio HO112RG-W3V3

From our tech experts at CEN

A JL Audio 12 inch subwoofer supplied in a HO Wedge ported enclosure, handling 500w RMS. The box is built to the driver’s specification rather than to fit a shelf.

Who it suits

Drivers who want the result without commissioning a custom build. Ported enclosures play louder and dig deeper for the same power, at the cost of size.

Our tech experts advise

Match the amplifier to the enclosure’s rating rather than the driver’s headline figure, and secure the box properly: an unrestrained enclosure is dangerous in a crash. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions

Q: Do I need an amplifier for this subwoofer?

A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.

Q: What does RMS power mean?

A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.

Q: Can CEN build or supply an enclosure and fit everything?

A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.

Q: How much amplifier power does the HO112RG-W3v3 need?

A: It produces strong output with as little as 150W, but performs best with 300 to 500W of amplifier power into its 2 ohm nominal impedance. It is rated at 500W RMS.

Q: How big is the HO112RG-W3v3?

A: It measures 819 mm wide, 387 mm high and 343 mm deep, with a top surface depth of 190.5 mm. The angled back lets it sit tightly against the back of a rear seat.

Q: Does the HO112RG-W3v3 include a grille?

A: Yes. Three solid aluminium bars protect the woofer.
