New Motor Design
The speaker features a newly designed motor that supports greater cone movement, reducing the risk of bottoming out and enabling higher excursion—making it a true high-excursion driver.
Maximum Power Handling
The voice coil uses a Till former/bobbin coated with VC Bonder 360, resulting in a design that withstands extremely high temperatures, allowing the speaker to handle high power levels reliably.
Robust Chassis Design
Built from durable die-cast material, the chassis is equipped with air vents on the bottom for effective airflow and efficient heat dissipation.
Efficient Air Compression
The driver is engineered with optimized airflow circulation, contributing to balanced air compression and improved overall performance.
Weatherproof Conepaper
The conepaper is coated with a special weatherproof layer, making it highly resistant to the humid and tropical conditions typical of Indonesia.
