EZA UHF Gain Technology

Different from ordinary BA, the ultra-high frequency attenuation is greatly reduced due to the optimization of the structure, which can obtain a very high extension.

We all know that the higher the frequency, the more the sound waves propagate in a straight line, the weaker the ability to turn over obstacles, and the ordinary BA sound direction is at an angle of 90 degrees with the direction of sound wave generation. Ultra-high frequency sound waves are severely reduced. but the EZA technology's BA sounds in the same direction as the sound wave, and its ultra-high frequency performance is better than ordinary BA.

Excellent frequency response curve feedback

The low-frequency peaks that are basically the same level as the mid-frequency bring a balanced and comfortable low-frequency quality, and the mid-low frequency with a recessed 6hz brings a clean background, but the vocal base will not be too thin.

The 6khz auricle gain section of the mid-frequency rises 2 times the sound pressure, the human voice is full, the distance is moderate, the high frequency is equal to the middle frequency, the sibilance range is reduced by 6db, the high-frequency is balanced, and the sibilance is less. 15k UHF 12db, eza driver brings excellent High-frequency extension.
