Features

1. High heat resistance and minimal compression The use of ISV (Interleaved Sandwich Voice Coil) technology enhances the speaker's resistance to high temperatures, complemented by ventilation in the motor assembly and chassis for improved airflow. 2. Low distortion An aluminum ring added to the head yoke reduces distortion, resulting in cleaner sound reproduction. 3. Weather resistance The cone features a carbon fiber blend and a special coating on both the front and back. This reinforces the structure and provides weather resistance, making the speaker suitable for both indoor and outdoor applications. 4. Specially designed chassis The chassis is constructed from robust die-cast aluminum and incorporates a heat sink and air vents to dissipate heat effectively. 5. "Super" low-frequency response A dual-damper design enables deeper, balanced excursion, allowing for lower frequency reproduction without distortion. 6. "Bulletproof" tinsel leads The reinforced cable construction withstands extreme subwoofer movement, ensuring durability and preventing breakage.
