Description

STAX SR-009S New flagship
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
Aluminium is a metal good for sound and a 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 integrated 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 speaker.
EARPAD
The earpad of a new design is carefully made by a craftsman’s hand and features both real leather with a good humidity environment and 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 forms with individual differences.
