The DVX PSW218 Passive Subwoofer from dB Technologies is a compact, high-output, passive subwoofer equipped with two 18" woofers. It is able to produce a maximum SPL of 140 dB and handles 4000W peak power. The cabinet is designed to achieve tight and maximized output and ensures acoustic response down to 28 Hz, resulting in a fast and controlled reproduction of the bass-frequency range.
The birch plywood enclosure is painted with black, heavy-duty paint, which ensures resistance to scratches and to the rigors of the touring environment. A strong 1.5mm metal grille protects its front panel, and the four lateral handles provide for easy transportation. For stacking DVX 2-way speakers or another subwoofer on top of the DVX PSW18, the subwoofer features recesses on the top. Additionally, there is an M20 pole-mount plate which allows for the placement of any speaker with 36mm holes on top of the DVX PSW18 by using the optional DS2-S pole-mount adaptor. The rear panel features two Neutrik Speakon connectors in a recessed input plate. On each corner there is a set of holes to accomodate the optional 4-wheel accessory kit (DWK 20). The lateral part of the DVX PSW218 features recesses for feet-mounting for lateral orientation.
