Heat Resistant
An added cooling device on the T-yoke helps maintain speaker temperature, ensuring stable performance.
The voice coil uses a former made of non-conductive fiberglass and wire coated with advanced technology, allowing it to operate even at temperatures above 280°C.
Low Distortion
An aluminum ring is added to the T-yoke to effectively suppress distortion, resulting in cleaner sound output.
Durable and Low Compression
The chassis is precisely engineered from aluminum die-cast material, providing maximum strength and reduced air compression for better airflow.
Stable with High Excursion
A double damper and triple round surround design make the speaker more stable and allow greater cone excursion for better sound dynamics.
Optimized Magnet Power
The motor's magnetic force is optimized using advanced FEA (Finite Element Analysis) simulation technology, ensuring efficient magnetic performance.
