Product Description

Stax SR 009

“super engineering plastics”

The newly developed sound element has been adopted in the Stax SR 009. New high polymer ultra-thin film material called the super engineering plastics – the reinforced material of the conventional engineering plastics –  employed for the diaphragm of the sound element. Materials superior especially in tone quality have been selected to attain the extremely excellent frequency characteristic from low to super-high as well as the vast dynamic range.

New electrodes named MLER (Multi-Layer ElectRodes) have also been developed to realize the plane drive of the whole film diaphragm surface. While infinite thinness and flatness are required for the fixed electrodes. At that time, they simultaneously need to have other characteristics such as low resonance. And the high transmissivity of the sound waves, and so on.

The entirely new electrodes have been completed through the unification of metal plates processed with ultra-precision photograph etching using the high technology of heat diffusion combination on the atomic level.

Aluminum framework on Stax SR 009

Firstly, STAX picked Aluminum for the framework citing the metal’s physical qualities. Which they regard as an excellent material for sound chamber suitable for audio equipment. Secondly, Uses the metal extensively throughout the whole design including the outer frame and elements of the framework. That houses the driver inside, to realize high-quality sound, rigidity, and lightweight. Finally, Manufacturing every part of the SR-009S through precise machine processing.

Cable

Silver-coated high-purity copper wire of 99.9999% (6N) purity is adopted for the cable. In addition, built-in a structure that is most suitable to drive the ear-speaker.

Earpads

Handcrafted with a new design, using genuine high-quality leather to make the earpads. The extremely comfortable cushion allows hours of comfortable listening to music.

Stax SR 009 ARC (head-band):

The equipment of arc on the Stax SR 009S is with a 10-step adjustment mechanism that you could glide to fit different head sizes.
