The SR-009 from Stax reinstates the company’s belief that a technology need not only be high-tech but it should also be able to produce refined, sensitive music for the ears. This “millennium” ear speaker (electrostatic headphone) is a result of constant research and hard work of the Stax team.

Thin diaphragm

The SR-009 features a newly developed material employed for the diaphragm of the sound element. The all-new high polymer ultra-thin film material known as the super engineering plastics is the reinforced version of the conventional engineering plastics. 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.

Cable

This “millennium” ear speaker makes use of the high-purity copper developed from the necessity of wiring large-scale integration circuits. Also known as high-quality audio cables, these high-purity copper wires of 99.9999% (6Nines) purity adopted for the cable is further silver-coated and finished with the most suitable structure to drive the ear speaker.

Multi-layer Electrodes

Stax SRH-009 incorporates use of new electrodes named MLER (Multi-Layer Electrodes). They have been developed to realize the plane drive of the whole film diaphragm surface. 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. They are thin, flat, have low resonance and facilitate high transmissivity of sound wave.

Aluminum Enclosure

Almost every part of the SR-009 is manufactured through precise machine processing using Aluminum, which is a metal good for sound and suitable material for audio equipment. This rigid and lightweight metal has been abundantly used, e.g. at the frame supporting the appearance and sound element, to realize high-quality sound.
