14.2mm Large Size Beryllium-Plated Diaphragm Driver

Good sound comes not only from the size of the sound-generating unit but also from the material of the diaphragm. After many tests by the acoustic R&D team, we have equipped the EMX with a beryllium-coated diaphragm dynamic driver, using the unique beryllium diaphragm material. Rigidity and thinness, the low-frequency performance is magnificent, and the sense of speed and power is more clean and neat.



Excellent New-Designed Geometry Shape

The beauty of minimalist geometry produces a sense of smooth lines, which directly hits the visual aesthetic. The cavity design brings a transparent and atmospheric sound bottom, creating a rich and full low-frequency experience, and the sound field shocks.


The Aluminum Alloy Cavity & Half-Open Exhaust Design

EMX follows the fine workmanship and solid materials of TRN, and adopts an all-aluminum alloy cavity formed by five-axis CNC precision cutting, which effectively suppresses resonance and brings more comfortable and natural high-frequency extension performance.



Professional Acoustic Structure

The professional acoustic structure design provides a stage for the dynamic unit to display its strength and satisfy the discerning ears with its strength. Fully exploit the power of the dynamic driver. The EMX cover with a half-open exhaust design, It can effectively suppress the refraction of sound waves in the cavity, making the bass dive better and more powerful.



High-Purity Cable With Interchangeable Audio Connectors
