GENERAL DESCRIPTION

The dB1800a is a self-powered subwoofer featuring an 18” heavy duty driver, complemented by a 500 Watt power amplifier. The dB1800a also offers an active stereo cross over providing a high-passed output for running your satellite speakers. Solid 3/4 inch plywood construction, steel corners, tough carpet covering and larger casters make the dB1800a a road warrior. In fixed installation systems, the dB1800a provides super tight low frequency output in a relatively small, unobtrusive enclosure. The dB1800a is a perfect add-on to your dB500 and Expedition system, or for any sound rein forcement system where extended low-end is desired. While using your dB1800a, you’ll have great low-end anywhere.
