Optimal Audio SUB 18 Black - Powerful 18” passive subwoofer designed for applications requiring high impact and performance in low frequencies across the Optimal Audio speaker range. The 18” (460mm) driver is mounted in a plywood bass-reflex enclosure that maximises performance, achieving a maximum SPL of 136dB while occupying minimal space.
Sub 18 can be used on the ground or suspended using integrated M8 inserts. The impact-resistant perforated steel grille protects the driver, while rubber feet prevent movement. The enclosure is made of plywood and finished with textured black paint. Integrated with Zone and WebApp, system setup and user control are simple and intuitive, with additional control options via ZonePad.
