STAX / R-X9000 Electrostatic headphones

STAX / SR-X9000 is a flagship model of the STAX brand that is equipped with the newly developed fixed electrode "MLER-3" that uses a large metal mesh and is the pinnacle of ear speakers.

■ 4-layer structure using metal mesh Newly developed fixed electrode MLER-3
-SR-X9000 is a new flagship ear speaker that exceeds SR-009S. In addition, the SR-009S multi-layer fixed electrode MLER-2 (Multi Layer Electrodes) is combined with a large metal mesh to evolve the 4-layer fixed electrode "MLER-3". The metal mesh with a fine opening is less affected by air resistance and reflection and has excellent sound transmission, making it an ideal material for fixed electrodes. The metal mesh is a part that has been difficult to mount on the fixed electrode due to the difficulty of manufacturing, but by applying the heat diffusion coupling technology obtained during the manufacturing of SR-009 and SR-009S, it can be mounted on the fixed electrode. It is now possible to hire.

■ Vibrating membrane that is 20% larger than the previous flagship
-The diaphragm that is the core of the sound uses an ultra-thin super engineering plastic film. Achieves excellent transient characteristics by reducing the mass as close to zero as possible, and improves sound followability over a wide range from low frequencies. Succeeded in increasing the diameter of the vibrating membrane by 20% compared to SR-009S. We have acquired a vast sound field that breaks the limits of headphone listening.

■ Aluminum machined housing that eliminates unnecessary resonance
-The main body that houses the sounding unit uses a tough machined aluminum housing. Adopted a new design that firmly fixes the sounding unit and thoroughly eliminates unnecessary resonance of the housing itself. By improving the acoustic characteristics in the housing, the clearer sound quality that is not affected by unnecessary resonance is acquired.

■ Tilt guard mesh structure
-The guard mesh installed parallel to the sounding body generates many direct reflections that adversely affect the hearing of the sound. In order to solve this problem, SR-X9000 adopts a strut structure with different heights in the front and back to change the height of the gap between the sounding body and the guard mesh. As a result, the guard mesh does not become parallel to the sounding body, and the reflection angle of the sound is successfully controlled. Achieves a smooth sound wave flow.

■ Stainless steel arc assembly with improved twist resistance
-Stainless steel is used for the arc assembly. We have increased resistance to twists and twists, aiming for a more stable listening fit. Genuine leather is used for the head pad that directly touches the head. The position can be adjusted with an adjuster that has a 10-step click mechanism.

■ Genuine leather ear pads with excellent breathability and fit
-Uses genuine leather (sheepskin) with excellent breathability and flexibility for the ear pads. You can keep the proper contact between the ear speaker and the head for a long time, and you can fully experience high-quality low-frequency expression and high-freshness sound quality. It also contributes to reducing fatigue and comfortable listening for a long time.

■ High-purity 6N OFC + silver-plated annealed copper wire Hybrid structure Wide low-capacity cable
・ 6N OFC high-purity annealed copper wire (φ0.14 × 3) with excellent low-frequency reproduction is used for the cable, and silver-plated annealed copper wire (φ0.08 × 9) with high high-frequency characteristics is placed on the outer circumference. It uses a replaceable re-cable mechanism and comes with two cables with 2.5m and 1.5m specifications that can be replaced according to the listening style.

■ A paulownia wood case with excellent humidity control effect
-Uses "paulownia wood" for the storage case. It has low heat conduction and excellent humidity control effect, and provides optimum storage conditions for ear speakers.
