General Description:
The Electro-Voice® PX2181 is a high efficiency dual 18”
subwoofer system that is part of the Electro-Voice
Phoenix Series and is intended for high output low
frequency sound reinforcement in fixed-installation and
portable sound applications. The PX2181 is configured
for biamping, and can be used with the PX2122 and
PX2152 for full range touring systems with extended LF.
The PX2181 uses dual DVX3180 woofers, a high
efficiency 18-inch woofer with forced air cooling. The
DVX3180’s are coupled to a low frequency horn for
maximum efficiency and punch. The enclosure is
constructed of 18-mm, 13-ply plywood, using tongue and
groove joints and EVCoat for long term durability.
The enclosure is designed to be placed in vertical and
horizontal configurations, and alignment cups are
placed in the enclosure to array multiple subwoofers.
Three PX2122’s can be placed on top of the PX2181 in
the horizontal configuration. A caster accessory is
available on the PX2181 for easy mobility.
A switch on the PX2181 allows connection of both
woofers to one amplifier channel in parallel mode, and
to be used with each woofer to an amplifier channel in
dual mode. In dual mode, three PX2181s can be
connected to two amplifier channels for maximum
flexibility.
