Commercial Series
Key Features:
Affordably priced, high-quality dualcone type ceiling speaker.
Pre-assembled speaker / transformer / grille assembly.
Suitable for most paging or background music applications, including retail stores, restaurants, schools, and other facilities.
Very high sensitivity provides maximum sound levels using minimal amplifier power.
Quality triple-voltage transformer (100V, 70V and 25V).
Packs of six pieces contain individually packaged speakers for shipping non-pack quantities to jobsite.
JBL’s Commercial Series Ceiling Speakers provide excellent performance for paging and background music applications. High sensitivity across the product line provides maximum sound level, even at low tap settings.
Model CSS8004 is a 100 mm (4 in) speaker with 90 dB sensitivity and a 5-Watt multi-tap transformer.
Model CSS8008 is an 200 mm (8 in) speaker with high 96 dB sensitivity, greater bass extension than the CSS8004, and a 5-Watt multi-tap transformer.
Model CSS8018 is a higher-power 200 mm (8 in) speaker, with very high 97 dB sensitivity and a larger 10-Watt multi-tap transformer.
The speaker’s pre-attached triplevoltage transformer provides versatility by allowing use on 100V, 70V or 25V distributed loudspeaker lines.
The drivers feature a full 25 mm (1 in) diameter voice coil with a Kapton coil-former and hightemperature wire for better power dissipation and long-term reliability. For installation convenience, the
speaker grille and transformer are preattached to the driver. Grilles are painted, zinc-plated, cold-rolled steel. The 200 mm (8 in) models feature a standard 286 mm (11¼ in) boltmounting diameter. Matching CSS backcans are made of zinc-plated steel with powder-coated finish. CSS steel pre-install backcans can be installed, wired, and inspected prior to installation of the speaker.
