dB Technologies Sub18D Digital (Sub 18 D)

SUB 18 D

Active 18“ band-pass Subwoofer

The SUB 18D is the first-choice bass bin for users seeking powerful punch and ultra low-end response. Fine-tuned to augment and amplify the high-power 18” woofer’s audio performance, this custom-engineered band-pass enclosure outperforms conventional bass-reflex designs, achieving higher peak levels. A single SUB 18D, paired with, say, two Opera Live 402/405 cabinets, constitutes an extremely efficient and flexible satellite system for entertainers and DJs.

Even a configuration as lean as this meets high expectations for bass response. Channels routed into the top panel make it easy to stack units and set up larger PA systems, for example, in combination with Flexsys F212 mid-/high-range units. The SUB 18D cabinet leaves small footprint that belies its high performance. And its low weight comes courtesy of the integrated ultra light digipro® digital power amp – and it comes as a very pleasant surprise.
Equipped with optional100 mm casters, the unit is easy to transport.

Integrated System Controller

The integrated system controller in SUB 15D and SUB 18D cabinets operates in mono and stereo modes and adapts the cabinet to suit different satellite speakers and mid-/high-range units. It offers two switchable phase settings, 0° and 180°, as well as a choice of two cutoff frequencies.

Control LEDs afford users a view of the current operating status. A professional-grade locking Neutrik® PowerCon connector with a parallel output (Link) connects the enclosure to the mains supply.
