JL Audio 8W7 / 8W7AE Subwoofer Voice Coil

JL Audio 8W7 / 8W7AE Subwoofer Voice Coil

The JL Audio 8W7 / 8W7AE  has earned a reputation as one of the finest 8″ subwoofers ever made. When the voice coil fails, rebuilding is almost always the smarter move. Our single 3 Ohm voice coil is a direct replacement that gets your subwoofer back to full performance for a fraction of the cost of buying new.

What Else Do You Need?

Along with the voice coil, you will typically need the correct spider and cone collar to complete the repair. Since replacement cones for the 8W7 are not available, you will need to reuse your existing cone.

For that reason, confirm your cone and dust cap are still in good condition before you start. In addition, we carry the matching spider, surround and cone collar to complete your repair.

Recommended Adhesives

Using the right adhesives is the difference between a repair that lasts and one that fails prematurely.

• EC4000 Rubber-Toughened CA Glue— for gluing the voice coil to the spider and cone
• FLXEP860 Semi-Flexible Black Epoxy — an alternative to CA glue for gluing the voice coil to the spider and cone
• BEP870 Black Epoxy – an alternative to CA glue for gluing the voice coil to the spider and cone
• L3890 Thick Black Rubber Adhesive — for attaching the dust cap

All four adhesives are available on our website. Using the wrong glue can result in a failed repair, so we strongly recommend using only these products.

Installation Tips

Dry-fit parts first and confirm alignment before final bonding. Before final assembly, meter the voice coil to confirm the impedance is correct. Then use the proper adhesives for spider-to-voice-coil and cone bonding, and allow full cure time before applying power.
