Adire Audio Subwoofer Cone

Carbon fiber is prized for its exceptional stiffness-to-weight ratio. This rigidity prevents the cone from deforming under high pressure, which minimizes distortion and ensures your subwoofer produces cleaner, more accurate bass even at high volumes.

This cone features a 3.07-inch (78mm) voice coil opening. You should measure your voice coil former diameter precisely before purchasing to ensure a proper fit, as even a slight mismatch can compromise the structural integrity of the assembly.

The large roll foam surround is designed to facilitate significant excursion, allowing the cone to move further back and forth without restriction. This is essential for moving more air and achieving the deep, impactful bass response typically required for high-performance subwoofer builds.

While the 14.76-inch outer diameter is standard for many 15-inch drivers, compatibility depends on the specific geometry of your basket and the surround's mounting requirements. Always verify your basket's mounting flange dimensions against the cone's surround width of 1.57 inches to ensure it will seat correctly.

For a secure, permanent bond between the carbon fiber cone and the voice coil former, a high-strength, heat-resistant epoxy or specialized speaker adhesive is recommended. Ensure the surfaces are properly cleaned and prepped to handle the mechanical stress the subwoofer will endure during operation.
