Jbl Professional 8124 Open Back Ceiling Speaker 4 Pack

Product Description

The JBL PROFESSIONAL 8124 is a 4-inch open back in-ceiling speaker designed for permanent installation in commercial and residential audio distribution systems. Open back construction allows the ceiling cavity to act as an enclosure, simplifying installation in drop-tile and drywall ceilings where a dedicated back can is not practical. This listing includes four speakers, making it a straightforward solution for multi-zone or multi-room installs. Audio/visual integration technicians and low-voltage contractors are the primary trades that specify and mount these units.

The 8124 is suited for background music, paging, and ambient audio applications in light commercial spaces such as offices, retail environments, hospitality venues, and multi-room residential systems. The 4-inch driver format fits standard ceiling cutouts in areas where space or aesthetic constraints favor a smaller form factor. Four speakers per pack aligns with common room-coverage layouts and reduces per-unit procurement steps for contractors outfitting multiple zones.

Installation Notes

Installation should be performed by a licensed low-voltage or audio/visual contractor in accordance with applicable NEC low-voltage wiring requirements. Power down the amplifier or distribution system before making any speaker wire connections. Use a ceiling cutout template if provided, and confirm ceiling material and joist spacing before cutting. Do not exceed the amplifier output rating specified for the speaker tap or impedance load.
