Used Electrovoice PX2181

The Electrovoice PX2181 is a dual 18-inch horn-loaded sub-scoop loudspeaker system built for high-output low-frequency sound reinforcement in both fixed-installation and portable sound applications. It houses two DVX3180 18-inch transducers with forced air cooling, each coupled to a low-frequency horn. Power handling is rated at 1000W continuous and 4000W peak, with a maximum SPL of 141 dB.

The PX2181 has a rear-panel switch that lets users choose between dual mode and parallel mode. In dual mode, each of the two DVX3180 woofers connects to its own amplifier channel. In parallel mode, both woofers are driven from a single amplifier channel. This flexibility suits different amplifier configurations and rig sizes without additional hardware.

Yes. The PX2181 is configured for biamping and is designed to be paired with the PX2122 and PX2152 loudspeakers for full-range touring systems with extended low-frequency coverage. In the horizontal orientation, three PX2122 cabinets can be stacked directly on top of the PX2181, making system integration straightforward.

The PX2181 is part of the Electro-Voice Phoenix Series, a line from EV, an American professional audio manufacturer with a history spanning microphones, loudspeakers, amplifiers and signal processing for sound reinforcement and commercial installation. Within the Phoenix Series, the PX2181 serves as the high-output subwoofer anchor, designed to partner with Phoenix full-range cabinets in touring and fixed-installation rigs.

Check that both DVX3180 drivers are functioning and that the dual/parallel mode switch operates correctly in each position. Inspect the 18-mm 13-ply plywood enclosure for structural damage, particularly at the tongue-and-groove joints. Confirm whether the optional wheel and caster kit is included, as this affects transportability. Used listings on this page vary by condition and included accessories.
