The pair of white MTC-16WG High-Humidity Accessory Grilles from JBL allows the Control 10 Series 16C/T, 26C, and 26CT Ceiling Speakers to be used in environments with high humidity. The aluminum alloy material does not rust and the durable powder-coated finish prevents pitting that could otherwise occur with raw unfinished aluminum. The white polyester finish matches the look of the speaker.
The grille installs in place of the one that comes with the speaker and can be attached by press-fitting it directly onto the speaker (pressing closer to the edges is recommended so as not to dent the grille due to too much pressure at one location). A scrim is glued to the back of the grille to help break up driving precipitation that might reach the speakers.
