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.

        Comments about Adam Professional Audio Sub2100 - 1000W 21" Front-Firing Active Subwoofer:

        I purchased this subwoofer to go with my Genelec 1038b mains. it did add a "little" to the Verry low end. However Adding a Subwoofer Alters the responce Curve and made allot of really good music sound bad. from what ive read in countless forums, to get a good responce you need to have everything all in the same cabinet.In Sumation, This is No Where near the [$] Price tag. if you need more bass in your system, Just Buy bigger Mains. I would Highly Recomend the Genelec 1038b.
