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. By eliminating standing waves and smoothing system response, AMTS renders high frequencies with a refreshing accuracy and clarity with all genres of music. An Exciting New Sound Corina’s new tuning offers a weightier and more percussive bottom end, with a wider and deeper soundstage, a stronger bottom end, and a smoother, richer midrange. Corina delivers a fun yet lifelike tone, sumptuous vocals, and bass that really kicks. Unlike many electrostatics, Corina is even fun with electronica and rock. The Metamaterial Revolution Continues Corina integrates our state-of-the-art Advanced Metamaterial Tuning System (AMTS), allowing us to re-imagine the voicing of Corina to deliver the most natural midrange we’ve heard in an electrostatic to date, with a top end free of annoying treble spikes. New Features Include AMTS for a smoother midrange and top end. New self-adjusting headband for a more comfortable listening experience Re-engineered 88mm driver with more consistent diaphragm tension and uniformity for enhanced linearity and better channel matching Matched ear pads for better imaging New ergonomic ear pad design with suede contact surfaces for comfortable extended listening.
