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.
