The NEXO eLS18 is the largest subwoofer in the eLS installation series, housing an 18″ high-excursion driver in a bass-reflex enclosure that reaches down to 32Hz with a peak SPL of 138 dB. Built for large-scale permanent installations — theatres, concert halls, large venues, and houses of worship — where deep, authoritative low-frequency output is non-negotiable. Constructed from 15mm baltic birch plywood with integrated rigging points, it pairs with NEXO ePS loudspeakers and is driven by NEXO nanoNXAMP or DTD controllers.
