DB Technologies SUB-18H 18" Semi-Horn-Loaded Active Subwoofer, 1500W

The dB Technologies Sub 18H subwoofer is part of their H Series of active subwoofers and offers remarkable specifications and user-friendliness.

With 1,500W (2,000W Peak Power) and a high-performance 18" woofer with 4" coil, the Sub 18H is well suited for applications where maximum low end extension is needed. Thanks to the Sub 18H's unique configuration, termed Hybrid Horn-Loading, the box can be tuned to the lowest frequencies to improve system efficiency and convey a deep, enveloping sound. Unlike conventional horn loaded systems, the Sub 18H sub ensures excellent efficiency even at close listening distance, which makes it suited for use even in small venues.

The Sub 18H 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). The delay helps you to improve the correct coupling with the whole line-up of dB Technologies full-range speakers, and to make advanced subwoofer configurations without the help of any external processor (Cardioid or End-Fire or Straight Line). As a matter of fact, the built-in features - variable crossover frequency, phase and delay - allow the H Series to be compatible with any dB Technologies lines.

The Sub 18H also features a mini USB Type-B port to update system firmware and retrieve a telemetry log file that provides information on abnormal events, usage time and amplifier status.The latest-generation digital amplifier Digipro G3 ensures excellent performance and low energy consumption thanks to its highly efficient, yet very lightweight system. The auto-range digital power supply allows it to operate both on 110V and on 220V.

The 28/56 Bit DSP with 24 Bit/48KHz A/D conversion 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 thanks to polypropylene edges that protect it from scratching or impacts during transport. This unique Hybrid Enclosure Technology offers outstanding strength and durability, making your speaker truly road-ready, with its exclusive aluminum 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, and the DS2-S mini pole (sold separately) is also available as an option to adapt any dB Technologies speaker to the Sub 18H.
