Diamond Domes for the Tweeter

                     – Setting the New Acoustic Standard

Our 25 mm Diamond Domes for the Tweeter embody the highest level of acoustic innovation, delivering unmatched precision, clarity, and dynamic range for high-end loudspeakers. Manufactured using advanced CVD growth to create an ultra-pure diamond membrane, these domes combine extremely low mass with a Young’s modulus of approximately 1050 GPa—nearly three times that of beryllium and over five times that of aluminum. This exceptional stiffness pushes the first breakup frequency beyond 70 kHz, ensuring distortion-free pistonic motion well above the audible range.

Compared with traditional diaphragm materials such as titanium or aluminum, diamond’s density of 3.52 g/cm³ provides an ideal stiffness-to-weight ratio, enabling lightning-fast transient response and revealing micro-details in complex musical passages. Its thermal conductivity, exceeding 1,300 W/m·K, also allows outstanding heat dissipation, maintaining stability and performance during high-power playback. The result is an ultra-responsive high-end acoustic diaphragm that captures every nuance—from the shimmer of a cymbal to the delicate breath in a vocal line—with lifelike accuracy and effortless transparency.

While the 25 mm dome is the ideal format for tweeters, our manufacturing capabilities extend far beyond. We can produce diamond acoustic diaphragms up to 100 mm in diameter—the largest size currently available worldwide—opening new possibilities for midrange and full-range applications where the benefits of diamond can transform the listening experience.

For audio engineers, speaker designers, and discerning listeners, diamond domes for the tweeter are not just a premium choice—they are the ultimate solution, merging advanced materials science with pure musical artistry.
