JBL 8124 - 20W 4-inch Passive Full-Range 70V/100V Ceiling Loudspeaker with 130-Degree Coverage in White Finish

The JBL Professional 8124 is a 20W, 4-inch passive full-range ceiling loudspeaker designed to deliver clear, high-fidelity sound in commercial environments. This loudspeaker offers an ideal solution for distributed audio systems where efficiency and performance are key. The 8124 is engineered to provide maximum sound output with minimal power consumption, thanks to its high-sensitivity driver. This makes it perfect for use in applications where amplifier power may be limited, yet clear and consistent audio coverage is required. The loudspeaker's compact, easy-to-install design incorporates a 6W transformer with 70V/100V taps, offering versatile options for system integration.

One of the standout features of the JBL 8124 is its open-back design. Unlike many ceiling speakers that require a backcan for installation, the open-back design allows the 8124 to be easily mounted in environments where such a feature is not necessary. This streamlined design reduces installation complexity, making it a popular choice for commercial applications. Additionally, the speaker provides a wide frequency range from 60 Hz to 18 kHz, ensuring high-fidelity performance across a broad spectrum of sound. Its 130-degree conical coverage helps distribute sound evenly across a larger area, making it ideal for spaces that require broad, consistent audio coverage.

The 8124 is built with a contemporary sculpted grille that ensures it blends seamlessly into modern architectural settings. It also features a nominal driver impedance of 8 ohms, ensuring compatibility with standard audio equipment. With its lightweight design (weighing just 2.5 lbs) and simple installation process, the 8124 is an excellent choice for a variety of ceiling-mounted applications in commercial environments, including retail spaces, meeting rooms, and more. Whether you need to install a few units or a large number, the JBL 8124 offers exceptional value while maintaining excellent audio quality.
