DISC dB Technologies SUB 18H Semi Horn Loaded Active PA Subwoofer

Full Description

Can you hear the horns?

Everybody else in your venue will be able to. With its semi horn loaded design, the dB Technologies SUB 18H is capable of delivering staggering SPLs without sacrificing clarity or quality. And this can all be experienced from anywhere in the room, even at close listening distances.

Premium power

Re-designed and reinvigorated. Experience the phenomenal performance of dB Technologies' world-renowned Digipro G3 amplifier. This high-powered, ultra-efficient Class-D amp module has been crafted with meticulous attention to detail, providing you with up to 2000W (peak) of clean, reliable power. This premium amplifier boasts a lightweight design with a flexible switch mode power supply circuit for worldwide operation. And there isn't a fan in sight - the Digipro G3 runs silently using a new static cooling system complete with a new heatsink and high-quality components.

Intelligent processing

With its digital heart, the Digipro G3 amplifier ensures that your SUB 18H performs exactly the way it should at all times. Advanced 28/56-bit DSP handles the crossover of the loudspeaker's acoustic components, as well as the frequency response, limiter, and acoustic phase alignment. A/D conversion is handled at 24-bit/48kHz too. The result? Pure sonic bliss from start to finish.

Flexible performance

Make your sound your own. The SUB 18H is loaded with powerful tools that let you optimise your subwoofer's performance to suit a wide variety of applications and system configurations. Stereo inputs and selectable link or crossover outputs, a 90Hz/120Hz selectable crossover, a phase inversion switch, and adjustable delay up to 4.5ms. You can achieve a diverse range of advanced configurations without the need for any external processing.

Unique construction

A good subwoofer is defined by two key elements - its performance, and its reliability. Particularly for mobile performers. You want something that is going to sound great, but will also withstand the punishing nature of live performance environments and life on the road. That's why dB Technologies have ensured that every aspect of the SUB 18H is built to perform. Night after night, year after year.

The SUB 18H's unique cabinet design is crafted from robust multi-layer wood, ensuring that your sound is delivered with precision, whilst also being able to withstand knocks, bangs, and rowdy crowd members. But it doesn't stop there. A highly-durable PVC coating surrounds the entire cabinet. These layers work together in harmony to keep the precious internal components of your subwoofer safe. Combined with powerful protection circuitry, you can rest assured that your SUB 18H is more than capable in even the most demanding situations.
