Why Audiophiles Love This Driver
- Beryllium Film Diaphragm: An ultra-lightweight yet rigid beryllium diaphragm minimizes distortion and extends frequency response from 20Hz to 20kHz for faithful, full-spectrum sound reproduction.
- Double Chamber Architecture: The separated front and rear acoustic chambers create precise sound layering and a wider dynamic range — approximately 20% broader than conventional single-chamber drivers.
- Premium Metal Housing: Corrosion-resistant, precision-crafted metal construction ensures long-lasting durability and optimized acoustic pathways for consistent performance over 10,000+ hours of use.
- Professional-Grade Specs: 32Ω rated impedance, 105dB sensitivity, and a 400Hz resonance frequency make this driver ideal for critical monitoring and personal listening applications.
- Universal Compatibility: Designed for seamless integration with existing headphone and speaker systems via standard 3.5mm setups — perfect for DIY audio builds and driver replacements.

Frequently Asked Questions
Q: What type of diaphragm does this dynamic driver use, and why does it matter?
A: This driver uses a beryllium film diaphragm. Beryllium is prized in audio engineering for its extremely low mass and high stiffness, which allows the diaphragm to move faster and more accurately than standard materials. The result is lower distortion, a wider frequency response (20Hz–20kHz), and more detailed sound reproduction — making it a preferred choice for audiophile-grade builds.
Q: What does the double chamber design do for sound quality?
A: The double chamber structure physically separates the front and rear acoustic cavities within the driver housing. This separation reduces acoustic interference between the chambers, producing cleaner sound layering, better-defined bass, and a dynamic range approximately 20% wider than conventional single-chamber designs — delivering a more open and natural listening experience.
Q: Is this driver compatible with standard headphone builds and DIY speaker projects?
A: Yes. With its 10mm size, 32Ω impedance, and universal 3.5mm system compatibility, this driver integrates easily into a wide range of DIY headphone builds, driver replacement projects, and custom speaker assemblies. It works well with most portable audio devices and studio equipment.
Q: How many driver units are included in one purchase?
A: Each package includes 2 × 10mm beryllium diaphragm dynamic driver speaker units, so you receive a matched pair — ideal for stereo headphone builds or dual-driver speaker projects.
