dB Technologies SUB 15H Active Subwoofer Description The dB Technologies SUB 15H is a semi horn-loaded active subwoofer designed for small to mid-sized events that demand high-performance bass in a compact size. Powered by a 1000W (1400W Peak) Class D amplifier, this subwoofer features a high-performance 15" woofer with a 3" voice coil, delivering deep, powerful bass with a maximum SPL of 133dB. Its Hybrid Horn-Loading configuration enhances low-frequency response, making it ideal for live performances, DJ setups, and professional audio applications. The built-in DSP processor (56-bit) with 24-bit/48kHz AD/DA converters provides advanced system control, limiting functions, and delay adjustments for seamless integration with other speakers. With stereo inputs, selectable link/crossover outputs, a phase inversion switch, and a built-in delay (adjustable up to 4.5ms), the SUB 15H allows for precise audio tuning and easy configuration, including Cardioid, End-Fire, or Straight Line setups without needing an external processor. The rugged birch plywood enclosure with a black PVC cover ensures durability and portability, making the SUB 15H road-ready. A M20 threaded pole mount allows for secure mounting of full-range speakers.
