SC-223X Screen Channel Loudspeaker Overview

The DCS SC-223X is a three-way cinema screen channel loudspeaker engineered for medium to large auditoriums requiring controlled 90° horizontal coverage, high vocal intelligibility, and strong dynamic headroom. The system supports bi-amplified or passive operation for flexible cinema integration.

Engineered for High-Performance Screen Channels

Featuring dual 15-inch low-frequency drivers and a 10-inch midrange compression driver with a 1.4-inch exit and titanium diaphragm, the SC-223X delivers 37 Hz to 16 kHz frequency response with high output capability. The shallow 20-inch enclosure depth facilitates behind-screen installation while maintaining structural rigidity and acoustic consistency.
