JBL Professional MTU-3 U-shaped Lyre for AM5212 and AM7212 Speakers (Black or White Finish)
The JBL Professional MTU-3 is the official U-bracket for the AM5212 and AM7212 AE Series installation loudspeakers. Designed by JBL for clean and secure integration, it allows the enclosure to be surface-mounted—typically on a wall or ceiling —and its tilt can be precisely adjusted using its side slots. The MTU-3 is available in black and white (MTU-3-WH) to match the speaker's finish and is not compatible with the WRC/WRX outdoor versions.
The official dimensional drawing specifies an approximate width of 28.5" (≈ 724 mm ) and side ears of ~13.5" (≈ 343 mm ), dimensions designed to perfectly accommodate the AM5212/AM7212 and facilitate access to the enclosure’s threaded points. As a JBL recommended accessory on both model sheets, the MTU-3 simplifies hospitality, retail, corporate, education and house of worship projects where controlled coverage with a discreet aesthetic is desired.
