Product Description

The JBL L100 Black Quadrex Foam Grille Pair is designed for owners who want to restore the familiar front appearance of their vintage JBL L100 loudspeakers.

Each grille features a raised square foam pattern inspired by the classic Quadrex design. The deep black finish creates a contrasting appearance against traditional woodgrain cabinets.

Original vintage foam may become brittle, discolored, or damaged after years of exposure to sunlight, humidity, and handling. These newly made replacement grilles provide a way to refresh the speaker’s appearance while retaining its existing cabinet and driver configuration.

These are new replacement accessories, not original vintage JBL factory grilles. They are supplied without grille frames.
