Electro-Voice TX1181 - 18” Passive Subwoofer (Tour X) with Integrated Low-Pass Filter

The Electro-Voice TX1181 is a Tour X series subwoofer module designed as a low frequency complement to full range systems such as the TX1122 or TX1152 . It integrates an 18” high-excursion EVS-18S woofer inside a rigid enclosure constructed of wood (plywood + MDF) with EVCoat coating and a steel grille. Its internal 6 dB/oct low-pass filter allows it to be connected in parallel with the full range speaker on the same amplification channel , avoiding additional channels and processing when a quick and portable solution is required. It offers 100 dB of sensitivity and a maximum calculated SPL of 132 dB , with extended response up to 45–700 Hz (-10 dB) . It includes a top support for a speaker pole and fixing points for the TX-W1 wheel kit (optional).
