Founded in 1997 and headquartered in Sydney, Australia, DEQX is a pioneering audio technology company renowned for its advanced loudspeaker, crossover, and room-correction solutions.
Founded by Kim Ryrie, a co-founder of Fairlight Instruments, DEQX builds on decades of innovation in digital audio processing to deliver unprecedented accuracy in sound reproduction.
The company's patented technologies analyse and correct timing, phase, frequency, and room-acoustic distortions at the microsecond level, enabling audiophiles, recording professionals, and music enthusiasts to experience recordings with exceptional clarity, realism, and spatial precision.
Recognized worldwide for its engineering excellence, DEQX has become a trusted name in high-performance audio, continuing its mission to bring listeners closer to the original musical performance through groundbreaking digital signal processing and calibration technology.
The Pre-8 has all of our Pre-4’s features but includes DEQX-HD-Active crossovers. It provides digital output options for all channels and can also be used with passive speakers.
The new DEQX Gen4 speaker calibration and room correction processors feature an order-of-magnitude improvement in resolution, all-new digital and analogue hardware and unparalleled connectivity.

Introducing the DEQX Cloud
The DEQX Gen4 processors interface over the network to the DEQX Cloud™. The result is intuitive, cross-platform, zero-install speaker calibration and room correction.
Breath-taking audio performance
An ESS Sabre Pro ADC and DAC embedded in our custom circuitry and ultra-low noise power supplies deliver –115 dB THD+N (preliminary) from analogue input to analogue output. Our most transparent audio processor ever.
Unlocking next-gen performance
DEQX Gen4 massively surpasses our previous models in processing horsepower. A powerful hexacore ARM processor delivers higher time-domain resolution and better low-frequency phase resolution.
Unsurpassed usability
We've refocused on hardware usability, with a carefully selected set of features for each model, a large volume control with LED readout and 5.5-inch AMOLED touchscreen with customised glass front.
