TRN ST7

2DD+5BA Hybrid acoustic architecture

We have used a new dual-moving coil + five Balanced Armature architecture on the TRN ST7 to achieve more detailed performance. Employing a coaxial dual-moving coil, with the moving coil unit responsible for mid-bass and bass and the five Balanced Armature units working together to handle high frequencies and mid-high frequencies.

Coaxial dual-moving coil unit design

The TRN ST7 employs a 10mm + 6mm coaxial dual-moving coil design. The advantage lies in the 10mm LCP low-frequency diaphragm, which can provide a deeper low-frequency response, enabling the audio to perform exceptionally in the low-frequency range.

Transparent resolution - Custom high-frequency balanced armature unit combination

For the TRN ST7, we have meticulously crafted a combination of five Balanced Armature units. To achieve optimal resonance between the moving coil and Balanced Armature units, we have carefully tuned their resonance to naturally align with the resonance peak formed by the human ear's coupling.

Stunning Hi-Fi sound quality

The TRN ST7 employs a high-precision three-way crossover design that meticulously calculates the playback frequencies of each driver and rationally allocates the low, mid, and high-frequency ranges.
