The Electro-Voice TX1181 Tour-X is a high-power subwoofer that extends the low frequency performance of the EV TX1122 and TX1152 loudspeaker systems. The TX1181 Tour-X subwoofer uses the EVS-18S, a high-excursion 18" woofer, coupled to well-braced enclosure with large, low distortion ports, to add high-impact bass response to any fullrange loudspeaker. An integrated low-pass filter allows the Electro-Voice TX1181 Subwoofer to be connected in parallel with a TX1122 or TX1152 on a single amplifier channel, eliminating the need for additional amplifier channels and processing. The EV TX1181 subwoofer 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 EVCoat 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 TX1181 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. An integrated pole mount allows for elevating a TX1122 or TX1152, and integrated mounting points on the rear of the enclosure allow the optional TX-W1 wheel kit to be attached for easy portability.
