Why are ferrite magnets heavily preferred over neodymium for standard subwoofers?

Ferrite offers a massive cost advantage and thermal stability. While heavier, the weight is often beneficial in large speaker cabinets to reduce resonance. It also allows for larger voice coil diameters.

Do you offer double-stacked gluing services for extreme power drivers?

Yes, for high-excursion subwoofers, we can pre-bond two or three rings using specialized industrial epoxies, ensuring the poles are perfectly aligned before shipment.

What is the maximum diameter you can manufacture for a speaker ring?

We routinely produce giant rings up to 220mm outer diameter for 12-inch and 15-inch professional PA system drivers.

Industry Overview

Ferrite ring magnets remain the undisputed backbone of the global loudspeaker and subwoofer manufacturing supply chain. Unlike neodymium, ferrite provides massive, stable acoustic output without the volatility of rare-earth pricing. Our manufacturing process focuses on maximizing Br (remanence) and controlling the face-flatness of giant ferrite rings to ensure perfect adhesion to the speaker backplate and yoke.

Key Challenges We Solve

How our engineering approach mitigates risks in this sector:

Flux Uniformity: Eliminating magnetic “dead spots” to ensure linear voice-coil excursion.
Assembly Adhesion: Optimizing surface porosity and flatness so industrial glues bond perfectly to the basket.
Batch Matching: Narrowing the Br variance across shipments so that acoustic performance remains identical from batch 1 to batch 100.
