JBL CSS8018 - 20W 8-inch Passive 70V/100V Ceiling Loudspeaker with 10W Multi-Tap Transformer and 110-Degree Coverage in White Finish

The JBL Professional CSS8018 is a high-power 20W 8-inch passive ceiling loudspeaker designed to deliver outstanding performance for paging and background music applications. With a larger 10W multi-tap transformer and an impressive sensitivity of 97 dB, the CSS8018 provides exceptional sound output even at low amplifier settings. This dual-cone driver features a robust 25 mm (1-inch) voice coil made with Kapton coil-former and high-temperature wire, ensuring superior power dissipation and long-term reliability. The speaker's frequency range extends from 50 Hz to 17 kHz for the driver and grille assembly and from 90 Hz to 17 kHz when installed with the CSS-BB8 backcan, offering deep bass and clear audio quality across the spectrum.

The CSS8018 is equipped with a triple-voltage transformer supporting 100V, 70V, and 25V distributed loudspeaker lines, making it a versatile solution for various installation requirements. The transformer includes multiple taps - 10W, 5W, 2.5W, and 1.3W for 70V and 25V systems, and 10W, 5W, and 2.5W for 100V systems - allowing precise power matching. Its wide 110-degree coverage at 2 kHz ensures even sound distribution, making it suitable for commercial spaces like retail stores, restaurants, and schools. The pre-assembled design, which integrates the speaker, transformer, and grille, simplifies installation and reduces setup time.

The CSS8018 is constructed with durability in mind, featuring a painted, zinc-plated, cold-rolled steel grille in a clean white finish. It meets rigorous safety standards, including UL1480, UL2043, NFPA 90, and NFPA 70, when used with a UL-listed backcan. The matching CSS-BB8 backcan and other compatible options such as the MTC-81BB8 and MTC-300BB8 enhance acoustic performance while providing flexible installation options. The speaker's bolt mounting circle measures 11.25 inches, and the grille diameter is 12.9 inches, ensuring a secure and seamless fit in most ceiling systems. With a depth of just 2.9 inches behind the grille and a lightweight design of 3.5 lbs, the CSS8018 is both compact and easy to handle, making it a reliable choice for professional installations.
