The Heartbeat of High-Fidelity Audio
Premium Ring NdFeB Magnets tailored for high-end drivers, subwoofers,headphones,speakers and acoustic engineering.
Redefine Acoustic Performance
In the world of professional audio, every decibel of sensitivity and every gram of weight matters. Our Sintered Neodymium (NdFeB) Ring Magnets are engineered to replace bulky Ferrite magnets, offering the highest magnetic field strength per unit volume available today.
Why Top Audio Engineers Choose Our Magnets:
- Extreme Power Density: High BHmax (up to 52 MGOe) allows for compact yet powerful motor structures.
- Transient Response: Strong magnetic flux ensures the voice coil reacts instantly to signal changes, delivering crisp, punchy sound.
- Weight Reduction: Achieve the same magnetic force at 1/10th the volume of ceramic magnets—essential for line arrays and portable gear.
Engineered for Stability & Precision
A magnet is only as good as its ability to withstand heat and corrosion. We solved the common pain points of standard neodymium magnets.
High-Temp Resilience
Don’t let power compression kill your vibe. Our SH, UH, and EH grades maintain magnetic stability at operating temperatures up to 200°C (392°F), preventing demagnetization during high-power sessions.
Precision Geometry
Tight dimensional tolerances (±0.05mm) ensure perfect concentricity with your T-yoke and Washer. This minimizes flux leakage and maximizes the B-field in the magnetic gap.
Advanced Coating
Available in Ni-Cu-Ni (Standard), Black Epoxy, or Zinc. Our industry-leading coating processes exceed 48-hour Salt Spray Tests (SST) to protect against humidity and oxidation.
