JL Audio 12W7 Replacement Subwoofer Cone

This aftermarket subwoofer cone is built specifically for JL Audio 12W7 and 12W7AE subwoofer baskets. It does not fit other JL models such as the W6, W3, or W0. The cone matches the original W7’s dimensions, profile, and excursion geometry. It offers a practical and affordable way to restore performance without replacing the entire subwoofer or relying on expensive factory service.

Don’t Throw It Out — Rebuild It Instead

Many JL Audio owners don’t realize they can rebuild a blown 12W7. If the motor and basket are still intact, you can restore full functionality by replacing the soft parts — including the cone, surround, voice coil collar, voice coil, and spider.

However, JL Audio no longer services first-generation 12W7s. They only support the 12W7AE. That leaves most original W7 owners with limited options for repair.

Why Spend $1,449.99 on a New One?

A brand-new JL Audio 12W7AE retails for $1,449.99. Once you add shipping and labor, total repair costs quickly become excessive. Instead, rebuilding your existing subwoofer with high-quality aftermarket parts like this cone can save you hundreds.

Designed for Strength, Travel, and Output

This cone features a lightweight polypropylene diaphragm that reduces moving mass while maintaining strength. The high-roll foam surround allows smooth suspension motion and long excursion. Unlike standard designs, the surround rolls outward over the mounting flange, preserving cone area and improving output.

The cone includes a solid, reinforced bonding platform at the center, designed to work with a JL-style voice coil collar. The collar bonds directly to the cone and the voice coil — no cutting is required. This structure adds stiffness to the moving assembly and ensures a secure, factory-style fit for both the coil and dust cap.

Installation Notes and Add-Ons

To install this cone, you’ll need a voice coil collar (sold separately). This collar bonds directly to the cone and voice coil and is required for proper alignment and long-term durability.

We recommend using rubber-toughened adhesives for all structural bonds:

• Rubber-toughened black CA glue (medium or thick) or rubber-toughened epoxy – For bonding:

  • The voice coil collar to the cone

  • The collar to the voice coil

  • The spider to the voice coil

• CA glue or epoxy – For bonding the spider to the frame (if not stitched)

• L3890 rubber glue – For bonding the dust cap to the cone
  (Flexible, durable, and ideal for center cap adhesion)

• CA glue accelerator (kicker) – Optional for faster curing of CA joints

This cone does not include a dust cap, voice coil, or spider — all are sold separately in our store. We also offer a deep-dish W7-style dust cap, designed specifically to fit this cone and reinforce the center bonding zone.
