"At the core of it all, music is an expression of emotion, a celebration of life and a token of everlasting memories. Every part of the 109 PRO, from the premium materials we used to the intricate engineering, embodies that same emotion our favorite music makes us feel.”
Antonio Meze, Lead Designer and Founder of Meze Audio.
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.
Tasked 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.
Through its open-back design, we wanted the 109 PRO to be vivid and exciting, empowering the listener to connect with music on a deeper level.
Carefully tuned by our in-house engineering team, it offers emotionally engaging sound with great detail, clarity and just the right amount of punch. Its organic character, paired with superior dynamics, excellent imaging, and full-bodied vocals bring soul-stirring details to life. Besides, it's easy to drive from most devices, whether we're talking portable sources or intricate home setups.
The spider-shaped structure and the acoustically transparent grill inside the earcup expose the driver from both sides, creating our most open pattern to date. Following the principles of anthropometrics, we positioned the driver at a precise angle and distance from the ear, to achieve an ideal anatomical fit.
