Sub 18 is a powerful, high-performance, passive, 18” subwoofer designed for applications that call for increased impact and low frequency performance across the Optimal Audio loudspeaker range.
The 18” (460mm) driver is loaded into a plywood bass-reflex cabinet that maximises performance, with a peak SPL of 136dB, while taking up minimal space. Sub 18 can be used on the ground or flown using integral M8 inserts.
An impact-resistant perforated steel grille protects the driver, and rubber feet on the base resist movement. The Sub 18 enclosure is constructed from plywood and finished in black textured paint.
When teamed with Zone and WebApp, system set up and end user control is simple and intuitive, and can be further supplemented by ZonePad wall controllers.
