At the heart of the A10000 lies a 6mm CVD diamond dome — precision-cut from a 25mm slab of ultra-pure diamond grown in Germany. Known for its extreme stiffness and low mass, this diaphragm dramatically reduces distortion while preserving the most minute musical details.
However, diamond is notoriously fragile. To counter this, final engineers devised a custom frame structure that supports the diaphragm during high-speed movement, preventing microfractures and maintaining structural integrity. The result is a driver that delivers ultra-low distortion, exceptional transient response, and unshakable physical stability.
⚙️ Form Meets Function: Mechanical Innovation
To fully harness the CVD diamond’s potential, final reimagined the entire driver assembly:
- Heat-formed polyurethane surround: Seamlessly bonded to the diaphragm for optimal elasticity and weight distribution
- Short-length voice coil: Positioned closer to the N52 neodymium magnet for faster, more accurate response
- Anti-resonance screw-mounted driver module: Minimizes unwanted vibration, preserving tonal purity
Each unit is assembled and tuned in final’s Japanese facility, where proprietary tools and molds ensure unmatched precision and consistency.
The A10000 is paired with a newly upgraded silver-plated high-purity copper cable, developed in collaboration with Runcohsha. Wrapped in an ePTFE foam-insulated structure, the cable prevents electromagnetic interference while offering ultra-low capacitance, allowing the signal to pass through uncolored, undisturbed, and intact — delivering clearer imaging, deeper silence, and smoother extension.
The A10000 is not only an acoustic marvel but also a visual statement. Inspired by high-end Swiss watchmaking, the stainless steel housing is adorned with the Côtes de Genève wave pattern — a symbol of craftsmanship and mechanical artistry.
