Electro-Voice PX2181 Phoenix Series Dual 18" Passive Subwoofer
The PX2181 is a high-efficiency horn-loaded dual 18-inch subwoofer intended for high-output low-frequency sound reinforcement. With the ability to perform in either portable or fixed installation applications, the flexibility of the PX2181 makes it usable within a Phoenix system, a club installation, or as an add-on to much larger concert touring systems.
Designed to be placed in vertical and horizontal orientations, alignment cups are placed in the PX2181 enclosure to secure multiple subwoofers in an array. Up to three Phoenix top boxes can be safely placed within the unique grooves routed into two sides of the PX2181 in the horizontal position, while routed foot receptacles securely maintain a single Phoenix top box in the vertical position.
A switch allows the user to toggle between parallel mode (in which both woofers can be addressed by one amplifier channel) and dual mode (where each woofer can be addressed independently). In dual mode, three PX2181 subwoofers can be connected to two amplifier channels for maximum flexibility and output.
The PX2181 utilizes dual DVX3180 18-inch woofers, a high-efficiency design with forced-air cooling. When coupled to the dual low-frequency horns, the system achieves an amazing 105dB sensitivity, allowing for performance that is equally at home in a Phoenix system or a much larger touring rig. The enclosure is constructed from 18-mm, 13-ply plywood, utilizing tongue and groove joints and EVCOAT® for long-term durability.
