Why Choose This Voice Coil?
- High-Quality Construction: Made with pure copper wire wound in two layers for efficient electromagnetic response and consistent audio output.
- White Aluminum Sound Film: The lightweight aluminum former keeps mass low, enabling fast, accurate cone movement for tight, punchy bass reproduction.
- Wide Compatibility: Available in multiple diameters (19.5mm to 38.5mm) to suit a broad range of bass and subwoofer speaker models.
- Versatile Use: Functions as a replacement speaker component and is also suitable for voice coil linear motor applications where greater force and extended travel are required.
- Compact & Lightweight: Easy to handle and install, even for first-time speaker repair projects.
How It Works
The voice coil is attached to the apex of the loudspeaker cone. When current flows through the winding, it reacts with the speaker's magnetic field to produce the motive force that drives cone movement — converting electrical signals into rich, accurate sound.

Frequently Asked Questions
Q: What diameter bass voice coil do I need for my speaker?
A: This listing covers a range of voice coil diameters from 19.5mm to 38.5mm. To find the correct size, measure the outer diameter of the existing coil former in your speaker before ordering. Matching the diameter precisely ensures proper fitment and optimal acoustic performance.
Q: What is the advantage of a 2-layer pure copper wire voice coil?
A: A 2-layer pure copper winding increases the number of conductor turns within the magnetic gap, resulting in a stronger electromagnetic force. This translates to better sensitivity, improved power handling, and more accurate bass reproduction compared to single-layer designs.
Q: Can this voice coil be used for applications other than loudspeaker repair?
A: Yes. In addition to replacing a damaged bass speaker voice coil, this component is compatible with voice coil linear motor applications where a larger driving force and extended linear travel are needed — all operating on the same electromagnetic induction principle.
Q: Is this voice coil difficult to install?
A: The coil is designed to be lightweight and easy to handle. While basic speaker repair skills are recommended, many DIY audio enthusiasts find the installation process straightforward with the right tools and adhesive for speaker reconing.
