dB Technologies SUB 18H

Active subwoofer from H series that is equipped with a 1500W Digipro G3 Class D power amplifier and a high-performance 18" woofer with a 4" coil, featuring a unique termed hybrid horn-loaded configuration. Unlike conventional horn loaded systems, it ensures excellent efficiency even at close listening distance, which makes them suited for use even in small venues. It can be tuned to the lowest frequencies in order to improve the system's efficiency and convey a deep, enveloping sound. The subwoofer offers stereo inputs with selectable link or crossover outputs, a crossover frequency switch at 90 or 120 Hz, a phase inversion switch and built-in delay up to 4.5 ms (adjustable in 0.5 ms steps). It also features a mini USB Type-B port to update system firmware and a 28/56-bit DSP with 24-bit/48 kHz A/D conversion that provides sound performance above all expectations and perfect system control even under the most extreme operating conditions, thanks to its advanced limiting functions. The PVC faced birch plywood speaker box is extra resistant also thanks to polypropylene edges that protect it from scratching or impacts during transport. This unique Hybrid Enclosure Technology offers outstanding strength and durability, making the subwoofer truly road-ready, with their exclusives aluminium heavy-duty handles. The M20 threaded mount on the top end of the box permits any type of full-range speaker to be installed using a standard pole with M20 thread. Frequency response [-10dB]: 28 - 150 Hz. Max.
