The TX1181 is the perfect companion sub to the TX1122 and TX1152 when compact and portable performance is required. Utilizing the proven EVS18S woofer, the TX1181 effortlessly provides the low frequency energy needed to keep up with Tour X top boxes, as well as many other EV loudspeaker products. The integrated low-pass input filter allows for "single amp drive", and the high sensitivity and excellent power handling don't require an enormous, expensive amplifier to generate high SPL. The aesthetically unique Backbone grille not only looks great, but also provides greater strength and damage resistance than simple grille block designs. Proprietary ergonomically correct handles and angled input panels, and integrated screw-in style pole mount make the TX1181 easy to transport and employ in a variety of applications.
