Stax Launches New SR-X9000 Flagship Earspeakers

At the pinnacle of Stax's electrostatic earspeaker range is its new range-topping SR-X9000, surpassing its SR-009, and featuring the newly developed fixed electrode “MLER-3”.

Stax's newly announced SR-X9000 features the next evolution of MLER2, thanks to manufacturing improvements. According to Stax, “An etching electrode and a metal-mesh electrode are bonded using the diffused junction (thermocompression bonding). After two generations of STAX flagship models, STAX's manufacturing technology makes a significant contribution to the stable mass production of big round-shaped metal-mesh electrodes.” Stax says that the introduction of MLER-3 has led to “sound transparency evolved more smoothly than conventional multi-layer fixed electrodes. And the rigidity characteristic resistant to vibration also evolved.”

Frequency response is quoted as 5Hz – 42,000Hz, Electrostatic capacitance at 110pF (including cable), 145kΩ Impedance, Sound pressure sensitivity rated at 100dB / input 100Vr.m.s. / 1kHz, and DC580V Bias Voltage. The SR-X9000 weighs in at 432g without cable.

As the Japanese headphone specialist's new flagship offering, the SR-X9000 features a 20% larger area diaphragm over the SR-009S. The company says this also “realises the widest sound field ever.” The enclosure has also been redesigned and machined from aluminium, said to eliminate unnecessary vibrations. 

Comfort is also ensured thanks to a stainless steel arc assembly, more tolerant to torsion, and more stability when it comes to fit. Wrapped in genuine leather, the arc assembly features a 9-step click system for perfect fit and comfort.

The replaceable cables also feature 6NCu ultra-pure annealed copper wire in Stax's original wide parallel 6-strand cable. Both a 1.5m and 2.5m cable are supplied.

Completing the package is a storage case made of “paulownia wood” which Stax boasts “has low thermal conductivity and humidity control capacity.”

The Stax SR X-9000 are expected to be available in Australia around end-October, and are expected to sell for $9,500 RRP.
