Dan Clark Audio EXPANSE Planar Magnetic Open Headphones

Expanse

Designed, tuned, and built in San Diego, California

Dan
Clark Audio’s design goal is to never compromise on sound, comfort, or
aesthetics. EXPANSE is our ultimate open headphone statement and embodies everything we’ve learned since our inception.

Years in the making, Expanse sets a new standard in open-back headphone musicality, soundstage, detail retrieval, and comfort. Featuring Dan Clark Audio’s all-new 4th generation planar-magnetic driver and our breakthrough Acoustic Metamaterial Tuning System, Expanse delivers a stunningly smooth presentation to bring new depth and breadth to all your favorite music.

Acoustic Metamaterial Tuning System (AMTS)

Headphones are subject to standing waves in the higher frequencies, which can make instruments like strings, cymbals, 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.

With AMTS the upshot is high frequencies are rendered with a refreshingly smooth, accurate, and detailed delivery across all genres. (OK, bad recordings are still bad — we’re not magicians.)

Our Planar Magnetic Drivers Redefine “Detail”

Expanse’s all-new 4th generation planar-magnetic driver delivers the smoothest, richest, and most detailed experience we could create. It uses our patented v-Planar technology to reduce THD and improve low frequency extension.

But we didn’t stop there — the diaphragm is made on an all-new system for a more uniform and consistent tension, lower distortion, and better matching.

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 favourite 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 allowing 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 the way it was meant to be heard.

Mechanical Design Innovations

We set out to make EXPANSE a real design statement. It takes its cues from our closed-back STEALTH headphone, but adds an exciting and unique grill based on mathematical functions derived from the principals of generative design, for a truly unique and stylish look.

The teardrop shape is designed to mirror the shape of your ear, maximizing the experience and comfort of the headphone while minimizing the amount of space and weight required.

The leather headband’s fine blue stitching creates a quilted head-strap that’s not only gorgeous but is also functional and comfortable. The embroidered logo adds a dash of colour to Expanse’s all-black aesthetic.

This top of the hinge-free headband is made of Nitinol, an alloy of nickel and titanium. This unique material’s properties include superelasticity and shape memory, offering a spring force that remains constant over time and over a larger area, allowing the headphones to fit smaller and larger heads alike.

If it’s Not Comfortable, Game Over

If a headphone is not comfortable enough to wear for extended listening, the design is flawed — no matter how great it may sound.

Gone are the mechanical sliders for fit adjustment; Dan Clark Audio has designed a stable yet comfortable “self-adjusting suspension system” that seats the headphone just right, with no muss or fuss.

At just 418g EXPANSE is also one of the lightest super-premium headphones on the market. Taken together, our new vegan suede and “leather” ear pads, self-adjusting suspension, and lightweight chassis make EXPANSE so comfy you can just ignore it and vanish into your music.

And for portability or storage we incorporated AEON 2’s elegant folding gimbal structure into EXPANSE, allowing it to conveniently pack into a compact custom case that’s small and easy to stow.
