CP212-WØv3
Dual 12W0v3 BassWedge, Ported, 2 Ω
Enclosed Subwoofer System with Dual 12W0v3-4 Subwoofers, Dark Gray Carpet (600 W, 2 Ω) - Ported Enclosure
A ready-to-install dual subwoofer system built around two 12W0v3-4 drivers in a slot-ported BassWedge enclosure.
The slot-port runs along the bottom of the enclosure and fires on the same plane as the woofers to produce excellent extension and response smoothness. The port mouth is flared to minimize air-flow noises.
The ultra-versatile BassWedge shape has extended sides so that it can be placed with the woofers firing out or straight down, off the floor of the vehicle. The shape works equally well in forward or rear-firing installations. This gives you plenty of options for tweaking the loading of the enclosure into your vehicle.
This subwoofer system is shipped wired, loaded and ready to connect via a push-button terminal.

About the JL Audio CP212W0v3
From our tech experts at CEN
A JL Audio 12 inch subwoofer supplied in a BassWedge ported enclosure, handling 600w 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 size enclosure does this subwoofer need?
A: The recommended enclosure volume is listed in the Specification tab where the manufacturer provides it. As a rule, sealed enclosures give tighter, more accurate bass while ported enclosures deliver more output. Contact CEN if you would like a recommendation for your build.
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: Sealed or ported enclosure - which should I choose?
A: Sealed boxes are compact and produce tight, controlled bass suited to sound quality builds. Ported boxes are larger and produce more output at low frequencies, suited to those who want maximum impact. Either works well when built to the recommended volume.
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.
