  CSS3
 		  The CSS3 is a 2-way ultra-compact cinema surround loudspeaker. Featuring a 1” soft-dome tweeter with single 6.5” very high quality “HiFi-grade” woofer, the CSS3 delivers exceptional performance from a very compact and efficient package.
Despite the small size, the CSS3 delivers dynamic, uncoloured and very low-distortion sound reproduction, while the system voicing is specifically matched with Alcons’ pro-ribbon cinema sound systems.

The 16 ohms impedance enables an economical powering of up to 16 units (2 ohms) on an ALC amplified loudspeaker controller (2 channels driven). The system includes dedicated (passive) filtering and system equalizing.

The 15° slanted baffle together with the wide horizontal dispersion caters for a very smooth LF/HF blending, in installations where the surrounds are mounted closely to the audience. The CSS3 dedicated bracket enables optimized projection.
The enclosure design provides for low profile wall mounting, with the reflex vent located on the underside of the cabinet.

The CSS3 is powered and controlled by the ALC amplified loudspeaker controller; Through the SDP™ (Speaker Drive Processor) circuit, the ALC offers CSS3-specific drive processing with response optimisation, dedicated power and excursion protection, guaranteeing maximized performance with full system reliability and minimized maintenance.
