Meze Audio 109 Pro

DIAPHRAGM DESIGN
 
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.

 
Our research led to developing the 109 series Dual-Composite Diaphragm - a combination of Beryllium-coated polymer and cellulose-carbon fiber composite.

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.

SUPERIOR BUILD

The 109 PRO is all about comfort – from the structural design of the headphone to the choice of materials, all decisions were carefully made to ensure the final product rises to our highest standard, in terms of ergonomics. Once placed on your head, the headphones have to become unnoticeable, leaving you with nothing but the music.

With this perspective in mind, we combined walnut wood, zinc, manganese steel and vegan leather in a comfortable, lightweight, yet highly durable structure.
