The Sub series is designed for applications that call for increased impact and low frequency performance to the Optimal Audio loudspeaker range.

An impact-resistant perforated steel grille protects the driver in each case, and rubber feet on the base resist movement.

The enclosures are constructed from plywood and finished in black textured paint.

They can be installed on the ground, fixed to a wall or ceiling or flown.
