Meze 109 Pro

In a world of fast-paced technology, we bet on proven fundamentals. Our new 50mm dynamic driver, assembled and tuned with ultimate precision, allowed us to push the boundaries of speed, accuracy and dynamic range.

In order to meet the acoustic goals we set for the 109 PRO, we focused our R&D efforts on materials research for each of the driver’s components.

The quest for maximizing the sonic abilities of the headphone started with the diaphragm, where we focused on finding the perfect balance between mass and stiffness.

asked with improving the absorption of the vibrations is the copper-zinc alloy stabilizer ring, where the choice of materials contributes to significant reductions in distortion.

Alongside the two, lies the light and efficient neodymium magnet and copper coil. Together, they are encased in a CNC machined, high precision aluminum frame, proven to be exceptionally reliable.

Made of a carbon fiber enforced cellulose composite, the W-shaped dome is able to reproduce high-frequencies with incredible detail, clarity and definition. More durable than conventional alternatives used in dynamic drivers, yet lightweight, this composite helps reduce resonances that may lead to harmonic distortion.

The ultra-thin torus surrounding the dome is composed of Beryllium-coated semicrystalline polymer, measuring 22 microns in thickness. By applying the Beryllium coating through Physical Vapor Deposition (PVD), we aimed to increase the stiffness and durability of the driver, while still keeping it light enough to achieve a fast transient response. These qualities are also enhanced through the corrugations on the torus, which are precisely carved at a 45.5° angle.

Beryllium’s high damping qualities also help suppress unwanted resonances, giving the 109 PRO its neutral, vivid and transparent character.
