JBL CONTROL 24CT MICRO 4" Two-Way Ceiling Speaker (Single)
The Control 24C Micro and Control 24CT Micro are compact in-ceiling speakers, providing full, high quality sound for background music and music-plus-paging systems. ese speakers are ideally suited for a wide variety of applications, from restaurants and specialty retail stores to professional offices and airports. Low distortion and a smooth, natural frequency response make the Control 24C/CT Micro ideal for medium volume business music systems as well as for the medium to low SPL segments of larger or louder systems. Low frequency output can be augmented with the addition of one of the Control Contractor subwoofer models. Similar mid/high frequency voicing to other JBL Control Contractor loudspeakers can, in many systems, allow for mixing and matching of models within zones without requiring separate equalization.
Installation of the Control 24C/CT Micro is quick and easy. e loudspeaker is packaged with the backcan, grille, support backing bracket and tile rails. In addition, optional new construction brackets are available. e entire installation can be accomplished without requiring access above the ceiling. A template is provided for marking the cutout. An innovative Cshaped support backing plate can be installed from below through the cutout to reinforce the top of the ceiling material. Tile bridge rails are included which can be screwed onto the C-plate to extend support to the T-channel grid in suspended ceiling installations. After the speaker is fitted through the cutout, it is held securely in place via mounting tabs which tighten onto the C-plate, if used, or directly onto the ceiling material.
