<<Soft hemisphere treble>>
Dynaudio pointed out that since the voice coil is at the periphery of the metal film, there is a time difference between the sound and the dome part, while the soft hemisphere sound point is near the voice coil, and the phase distortion is low. At the same time, the soft hemispheric diaphragm has no basin segmentation distortion. In addition, the soft hemisphere treble decays slowly at frequencies above 23kHz, and the human ear feels that the high frequency extension is very good, close to real music reproduction. On the contrary, the metal body treble specification seems to extend better. Due to the steep attenuation of this part of the frequency, there is ringing at some frequencies, and the sound is unpleasant. In fact, the materials and construction inside Dynaudio's soft-dome tweeters have continued to improve, and performance has improved in parallel.

Dunaudio's new generation of tweeters has enlarged the back room, and installed a reverse-molded hemisphere (Hexis) to ditch the airflow, eliminate resonance, and make the frequency linear and the sound more detailed. In addition, the rear chamber of the tweeter is filled with more sound-absorbing damping material, which effectively absorbs the back wave energy and does not reflect back to the diaphragm.

Dynaudio's hand-coated soft hemispheric tweeters use large magnets, which are several times larger than some other manufacturers' products, and can accurately drive the diaphragm connected to the voice coil to produce sound. Because the soft hemisphere tweeter has a special technical motor system, it can carry 1,000 watts of input in an instant, and the sound dynamics are extremely high, surpassing ordinary metal film tweeters, so the sense of presence is more realistic.
