12TW3-D4 Shallow Mount

12-inch (300 mm) Subwoofer Driver, Dual 4 Ω

TW3 12-inch Subwoofer (400 W, dual 4 Ω voice coils)

Building on the core technology of our TW5 thin-line subwoofers, the TW3’s deliver a powerful combination of shallow mounting depth and excursion capability. In fact, they are capable of greater excursion than the W3v3’s.

To allow this remarkable feat to be achieved, JL Audio’s patented thin-line woofer technology compresses the architecture of the TW3’s using a “concentric tube” structure built into the injection-molded cone body. This structure supports the voice coil and a full annular spider, while permitting the placement of the large motor structure further forward in the speaker than with conventional designs.

TW3’s are optimized for small enclosures and offer our tab-ear mounting design to maximize cone area within their mounting footprints. We know you’re going to love working with these amazing Subwoofers.

Deep, powerful and accurate JL Audio bass is now possible in more applications than ever.

About the JL Audio 12TW3-D4

From our tech experts at CEN

A JL Audio 12 inch TW3 Series subwoofer driver, shallow mount for vehicles where depth rules out a conventional sub, dual 4 ohm, handling 400w RMS.

Who it suits

Drivers building a system around a properly specified enclosure rather than a box off the shelf. TW3 gives more output than TW1 while staying shallow.

Our tech experts advise

This is a driver, not a finished system: enclosure volume and tuning decide most of what you hear, and JL publish specifications worth building to, and the dual 4 ohm coils decide how it should be wired to your amplifier. We build enclosures to suit both driver and vehicle at our Beeston workshop. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs.

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.
