Sub 10 is a slimline, passive 10” subwoofer designed for applications that call for increased impact and low frequency performance to the smaller Optimal Audio loudspeaker range. This visually unobtrusive enclosure makes it perfectly suited where space is limited such as under banquette seating. 

It features a 10” (250mm) driver with a generously sized low frequency port for reduced air noise. With a peak SPL of 127dB this is a truly punchy little sub and can be used on the ground, fixed to a wall or ceiling 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 10 enclosure is constructed from plywood and finished in black textured paint.
