Optimal and Heat-Resistant Magnetic Power
Uses lightweight neodymium magnets that can withstand extremely high temperatures. The magnet design is optimized through FEA (Finite Element Analysis).
Minimum Compression
The voice coil/spool and motor parts are designed with special ventilation to eliminate air compression and provide effective airflow for cooling.
Low Distortion
A copper cap is added to the T-yoke, resulting in extremely low distortion levels.
Maximum Power Handling
The voice coil wire uses premium material (APISVCAW), which offers very high power handling and low mass for improved efficiency.
Special Conepaper Material
The conepaper is weather-resistant, made using the rigid non-press method, and combines special materials with carbon. This results in a very strong, durable, and lightweight cone that delivers excellent sound quality.
ISV: Interleaved Sandwich Voice Coil
ISV technology provides excellent heat transfer and reduces the operating temperature of the voice coil. It also enhances heat resistance, allowing the speaker to perform reliably at very high power levels.
Specially Designed Chassis
The chassis is made from high-quality die-cast material and features a special design on the bottom to ensure excellent heat dissipation.
