General Description: Technical Specifications:

The Electro-Voice® TX2181 is a dual subwoofer system that is de­signed to add high-output, high-impact bass response to the TX2152
loudspeaker system.

The TX2181 can move tremendous amounts of air, thanks to dual
EVS-18S high excursion woofers, a well braced enclosure, and a
low distortion port design. The EVS-18S woofers feature a 4-layer
voice coils and cast frames for high power handling and maximum
durability. The TX2181 is designed to be used with a processor and
a dedicated amplifier channel in a biamp configuration.

The TX2181 has many features that make it a versatile subwoofer
system. The enclosure is constructed out of a combination of MDF
and plywood, and coated with EVCoatTM for maximum strength and
durability. The unique grille design is very strong, dent resistant, and
features a rotatable logo. Four way handles allow for gripping the
TX2181 in a variety of positions. The recessed input panel with dual
NL4 connectors keeps the connectors hidden and allows for closer
placement to a wall or other boundary. The TX2181 is the same
width and height as the TX2152, providing a single column appear­ance when stacked, and uses the minimum amount of space when
stored or transported. Mounting points on the rear of the enclosure
allow the optional TX-W1 wheel kit to be attached for easy portability.
