Designed with high sensitivity, these speakers deliver maximum sound levels even at low tap settings, making them perfect for retail stores, restaurants, schools, and other facilities. The CSS8004 model features a robust 100 mm (4 in) dual cone speaker with 90 dB sensitivity and a 5-Watt multi-tap transformer, ensuring clear and efficient audio performance. Crafted for reliability and durability, our ceiling speakers come equipped with a 25 mm (1 in) diameter voice coil, Kapton coil-former, and high-temperature wire. These components enhance power dissipation and long-term reliability, ensuring that your investment lasts. The speaker grille and transformer are pre-attached to the driver for easy installation, saving you time and effort.

These back cans can be installed, wired, and inspected prior to the speaker installation, streamlining the setup process. The frequency range of the driver/grille assembly spans from 85 Hz to 18 kHz, and when installed in the CSS-BB back-can, it ranges from 130 Hz to 18 kHz.
