Heat Resistant
The 4-inch voice coil uses flat wire for reduced weight while maintaining high durability under extreme heat and power.
It also features a non-conductive fiberglass former and advanced coil wire coating technology, allowing it to operate even at temperatures above 280°C.
Robust and Low Compression
The new model chassis is precisely engineered from die-cast aluminum, offering maximum strength with minimal air compression for improved performance and cooling.
High Stability and Long Excursion
A triple round surround ensures greater stability and allows for longer cone excursion.
The non-press conepaper is coated on both the front and back, providing solid bass performance and weather resistance.
Optimized Magnet Power
The speaker’s magnetic motor power is carefully calculated using FEA (Finite Element Analysis) software.
Ventilation holes help reduce excess heat for better airflow and thermal management.
