HAD218 3000W Dual 18-Inch Long-Excursion Active Subwoofer for Professional Concert Sound Systems
Product Overview
The HAD218 is a high-output dual 18-inch active subwoofer engineered for large-scale sound reinforcement, touring productions, outdoor festivals, concerts, and professional PA systems.
Equipped with two long-excursion 18-inch neodymium woofers, the HAD218 delivers deep bass extension, powerful low-frequency impact, fast transient response, and low distortion. Its bandpass horn-loaded enclosure improves acoustic efficiency and produces the high sound pressure levels required for large venues and demanding live sound applications.
The self-powered design integrates a professional DSP plate amplifier, eliminating the need for an external power amplifier and simplifying system setup. Gain, delay, polarity, crossover, and limiter functions can be adjusted through USB or RS-485 control, allowing precise system optimization for different venues and deployment configurations.
Constructed from premium Russian birch plywood, the enclosure provides excellent rigidity, durability, and acoustic stability. A weather-resistant polyurea coating protects the cabinet against moisture, scratches, and transportation wear, while a heavy-duty steel grille backed with acoustically transparent foam protects the internal drivers.
With 3000W RMS and 8000W peak system power handling, the HAD218 is a reliable low-frequency solution for touring companies, rental systems, concert venues, and large-scale fixed installations.
