STAX – SR-009S

Multilayer fixed electrode MLER (Multi-Layer-Elect-Rords) established with SR-009 has evolved to MLER 2. The finish and etching process that smoothes the edge of the electrode opening reduces air resistance and further improves sound permeability. Also, the electrodes themselves are gold plated with high specific gravity to minimize the resonance of the ultra-thin electrode. At the same time, due to the effect of reducing the electric resistance of the electrode itself by gold plating, we have opened up a new ground for high speed, clarity, silky details, and powerful texture.

SR-009S adopts a diaphragm made of ultra-thin super engineering plastic film. The light mass has realized a high transient characteristic throughout the entire audio spectrum.

The main body was redesigned to further reduce resonance to provide a consistent sound.

 

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

 

CABLE:
The high-purity copper developed from the necessity of wiring large-scale integration circuits is also known as high-quality audio cables. High-purity copper wire of 99.9999% (6Nines) purity adopted for the cable is further silver-coated and finished with the most suitable structure to drive the earspeaker.

 

EARPAD:
The earpad of a new design is carefully made by a craftsman’s hand and features both the real leather with a good humidity environment and the cushion material with moderate elasticity.

The new earpad enables hours of comfortable listening to music.

 

ARC (headband):
The arc is equipped with a position adjustment mechanism of a 10-step slider and corresponds to the wide range of cranial form with individual differences.
