Buying Guidance

Precise specification matching is non-negotiable for these components — diameter, impedance, and material must match the original exactly. See our voice coil replacement guide for how to correctly identify a failed component's specifications before ordering.

Maintenance

Store unused components in a dry, temperature-stable environment — cone papers and adhesives can degrade in high humidity even before installation.
