The MTC-14WG and MTC-16WG address the weakest link when using ceiling speakers in high-humidity applications: a steel grille that can rust. These high-humidity grilles extend the longevity of JBL’s Control 10 Series model ceiling speakers, as their aluminum alloy material does not rust and the durable powder-coated finish prevents pitting that could otherwise occur with raw unfinished aluminum. The finish provides a nice look that matches with the speaker.
The MTC-14WG and MTC-16WG high-humidity grilles are available in either white or black. Details are here.
