KP-218S – Dual 18″ High-Power Subwoofer
The KP-218S is a high-performance dual 18-inch subwoofer engineered for large-scale professional sound reinforcement systems. Designed to deliver extreme low-frequency output with high efficiency and low distortion, the KS-218S is ideal for touring systems, stadiums, concert halls, clubs, and high-end fixed installations requiring powerful and controlled bass performance.
Product Description
- Dual 18-inch long-excursion woofers: Equipped with two high-power 18″ woofers featuring long linear excursion for deep, impactful low-frequency reproduction.
- High-efficiency motor structure: Optimized magnetic system delivers strong magnetic flux density, improving sensitivity and overall system efficiency.
- Large 5-inch voice coil design: High-temperature voice coils with extended winding height ensure stable magnetic force and excellent power handling under extreme operating conditions.
- Advanced cone technology: Rigid yet lightweight cone construction provides maximum structural stability while keeping moving mass low for fast transient response.
- Reduced distortion design: Multiple aluminum shorting rings effectively reduce intermodulation distortion (IMD), stabilize inductance, and minimize power compression at high excursion levels.
- Tour-grade enclosure: CNC-crafted, high-density birch plywood cabinet ensures durability, structural integrity, and consistent acoustic performance.
