Heat Resistant and Low Compression
The use of ISV (Interleaved Sandwich Voice Coil) technology enhances the speaker’s durability under high temperatures. Ventilation in the motor and chassis ensures better airflow, effectively reducing heat buildup and air compression.
Low Distortion
An added aluminum ring on the head yoke minimizes speaker distortion, resulting in cleaner and clearer sound output.
Weather-Resistant Conepaper
The conepaper is coated with a weather-resistant layer, making it durable and reliable in all weather conditions.
Specially Designed Chassis
Constructed from sturdy aluminum die-cast material, the chassis includes a heat sink and air vents to efficiently release trapped heat and maintain performance stability.
Extended Low-Frequency Response
A double spider design combined with deeper cone excursion enables the speaker to deliver richer and deeper low-frequency sound.
