Optimal Audio Sub 15-B

Sub 15 is a compact, high-performance, passive, 15” subwoofer designed for applications that call for increased impact and low frequency performance across the Optimal Audio loudspeaker range.

The 15” (380mm) driver is loaded into a plywood bass-reflex cabinet that maximises performance, with a peak SPL of 135dB, while taking up minimal space. Sub 15 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 15 enclosure is constructed from plywood and finished in black textured paint.
