Introduction
Thank you for purchasing the dB1500a or dB1800a Subwoofer by Samson. The dB1500a and
dB1800a are self- powered subwoofers featuring 15" for the dB1500a and 18" for the dB1800a
heavy duty drivers, complemented by a 1000 Watt power amplifier. The dB1500a and dB1800a
also offer an active stereo crossover 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 dB1500a and dB1800a road warriors. In fixed installation systems, the dB1500a
and dB1800a provide super tight low frequency output in a relatively small, unobtrusive enclo-
sure. The dB1500a and dB1800a are perfect add-ons to your dB500 and Expedition system, or for
any sound reinforcement system where extended low-end is desired. While using your dB1500a or
dB1800a, you'll have great low-end anywhere.
In these pages, you'll find a detailed description of the features of the dB1500a and dB1800a sub-
woofers, as well as a guided tour through their front and rear panels, step-by-step instructions for
their setup and use, and full specifications. You'll also find a warranty card enclosed—please don't
forget to fill it out and mail it in so that you can receive online technical support and so we can
send you updated information about these and other Samson products in the future.
With proper care and adequate air circulation, your dB1500a or dB1800a will operate trouble free
for many years. We recommend you record your serial number in the space provided below for
future reference.
