Acoustic Metamaterial Tuning System (AMTS)

Headphones are subject to standing waves in the higher frequencies, which can make instruments like strings, cymbals, and even vocals sound unrealistic and fatiguing.

AMTS is Dan Clark Audio’s patent-pending inline device located between the transducer and ear. AMTS integrates waveguides, diffusion control, quarter-wave, and Helmholtz resonators into one compact structure to eliminate standing waves, dramatically improving system performance.

Diffusion elements reduce standing wave formation while resonators act as both precision and broadband filters to smooth and shape the frequency response from the midrange through the highest frequencies.

EXPANSE Redefines "Detail"

EXPANSE’s planar driver delivers incredibly low distortion throughout the listening range with levels of detail heretofore found primarily in the top-of-the-line electrostatics. Unlike many headphones where “detail” is created through exaggerated high-frequency energy, EXPANSE’s AMTS delivers industry-leading resolution without fatiguing highs users may be used to.

Together, our 4th-generation motor and AMTS deliver a sonic performance best described as “effortless." From a delicately plucked string to the most intense dynamics of an orchestra, or the weight and attack of a kick drum to the overtones a decay of a crash cymbal, EXPANSE delivers an amazing balance of delicacy, nuance, and punch that will have you reaching for all your favorite recordings, and maybe staying up a bit too late.

 And last but not least, there’s the soundstage; EXPANSE is all-enveloping and can compete with any open headphone in depth, width, and imaging, with instruments occupying a correct volume in space instead of being rendered as “points”.

EXPANSE’s effortless sense of space and instrument placement allows the headphone “disappear,” so you can simply relax into your musical experience. Let the headphones, equipment, and, yes, your daily stresses melt away, leaving your music to be enjoyed how it was meant to be heard!
