Optimal Audio Sub 15
High-power sub-bass loudspeaker
Compact 15” subwoofer
The Optimal Audio Sub 15 is a high-output passive subwoofer designed to deliver deep, powerful bass for demanding commercial audio environments. Ideal for bars, event spaces, and leisure venues, it enhances full-range speaker systems with strong low-frequency impact, making it perfect for high-energy applications and larger spaces.
Description
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.
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.
