The Sub2100 from Adam Professional Audio is an active, front-firing subwoofer designed for strong bass response in large control rooms and studios. The large, 21" driver is housed in a specially-tuned bass-reflex cabinet to reproduce frequencies as low as 18Hz. A highly-efficient amplifier delivers up to 1000W of continuous power for a strong, linear performance with very little compression.
The rear panel of the subwoofer offers XLR and RCA inputs and outputs, as well as an XLR subwoofer output for daisy-chaining. A 180° phase control is provided, as well as gain and high-pass filter controls.
