JL Audio 13W6v2 / 13W6v2-D4 Foam Surround Speaker Repair Kit

JL Audio 13W6v2 / 13W6v2-D4 Foam Surround Speaker Repair Kit

The JL Audio 13W6v2 foam surround repair kit is designed to restore proper suspension function and cone movement in subwoofers with worn or deteriorated surrounds. Over time, foam surrounds naturally degrade due to age, heat, and environmental exposure. As a result, the cone can lose control and bass output becomes distorted. By replacing the surround, the subwoofer regains smooth movement and controlled low-frequency performance.

This kit uses a foam surround matched to the correct geometry and compliance required by the 13W6v2 platform. Because surround compliance plays a critical role in suspension behavior, using the proper foam helps maintain correct excursion and cone alignment. Consequently, the risk of cone rocking and voice coil rub is significantly reduced.

Restores Proper Suspension Behavior

The foam surround acts as a key component of the subwoofer’s suspension system. When the original surround fails, cone movement becomes uneven and uncontrolled. However, installing a correctly sized replacement surround restores the intended flexibility and centering force. As a result, the cone moves smoothly throughout its full excursion range, producing tighter and more accurate bass response.

Designed for Reliable Repairs

This foam surround repair kit works best for recones and repairs where the cone and voice coil remain in good condition. Instead of replacing the entire moving assembly, builders can extend the life of the subwoofer by restoring only the suspension. Therefore, this kit offers a cost-effective solution for maintaining performance without compromising reliability.

Installation Notes

Proper preparation is essential for long-term results. Before installation, clean all bonding surfaces thoroughly. During installation, apply a speaker-specific surround adhesive and allow adequate cure time. Additionally, accurate centering during the glue-up process helps prevent future alignment issues and ensures consistent performance.
