Frequently asked questions

What speakers does each accessory fit?

The MTC-14WG mounts only on JBL Control 12C/T and 14C/T ceiling speakers. The WB8 rough-in frame is designed for JBL C128W/WT in-ceiling speakers. They are not interchangeable.

When should I install each one?

Install the MTC-14WG after your speakers are already mounted, to add weather protection to outdoor venues or humid areas. Install the WB8 before drywall goes up during new construction, as a structural mounting bracket within wall cavities.

Do these products affect speaker sound?

The MTC-14WG is described as acoustically transparent and does not compromise acoustic performance. The WB8 is a structural mounting frame that does not alter speaker tone—it only stabilizes placement during construction.

What materials and durability can I expect?

The MTC-14WG uses aluminum alloy with powder-coated satin finish and includes a precipitation-blocking scrim. The WB8 uses heavy-gauge steel with powder-coat finish. Both resist rust and corrosion in their respective environments.
