36) 4" JBL Ceiling Speakers+6 Zone 70v Commercial Restaurant Office Amplifier

This high-count system pairs the Rockville RCS180-6 180W 6-zone 70V amplifier with thirty-six JBL CSS8004 4-inch ceiling speakers, covering large commercial spaces like multi-room restaurants, expansive retail floors, schools, and office buildings where full, even audio coverage is the priority. Each CSS8004 uses a 100mm dual-cone driver with 90 dB sensitivity and an exceptionally wide 175-degree dispersion pattern. That broad coverage means fewer dead spots between speakers, even with the compact 4-inch form factor. 70V taps at 5W, 2.5W, 1.3W, and 0.7W let you set each speaker's draw from the line, and 100V taps are also available.

The RCS180-6 amplifier delivers 184 watts across six independent zones, each with its own volume control. Bluetooth streaming, USB and SD card playback, FM tuner, optical input, and dual RCA inputs give you a wide range of music sources. Three mic inputs with individual echo controls and a chime button handle PA announcements and paging. Detachable euro-block speaker terminals simplify wiring across large installations, and a built-in clipping limiter with active cooling keeps the amp running cool through long commercial operating hours. With 36 speakers at low individual tap settings, you get consistent sound throughout the building while keeping total power draw well within the amp's capacity.
