Speco Technologies CBS4 Professional Communications Extension Speaker
Overview
The Speco Technologies CBS4 is a 10-watt, 4-inch deluxe professional communications extension speaker designed for integration into security systems, public address installations, and intercom deployments. This purpose-built speaker delivers consistent audio output across indoor and outdoor environments, providing integrators and system designers with a reliable component for distributed audio applications requiring multi-zone coverage or remote speaker placement.
Key Features
- 10W Output Power: Delivers adequate sound pressure level for typical security and communications environments without overdriving or distortion
- 4-Inch Speaker Cone: Optimized acoustic design balances frequency response and coverage area for voice communications clarity
- Deluxe Professional Grade Construction: Built to withstand repeated deployment cycles and integration into diverse system architectures
- Extension Speaker Designation: Designed as a secondary or remote speaker component, allowing flexible system layouts where multiple CBS4 units distribute audio across larger facilities or outdoor areas
- Integrated Audio Amplification Compatibility: Engineered for direct connection to standard communications control systems, amplifiers, and intercom platforms
- Robust Housing Design: Professional-grade enclosure protects internal components from environmental exposure during installation and long-term operation
Technical Specifications
The CBS4 speaker system operates at 10 watts of continuous output power, with a 4-inch driver delivering audio reproduction suitable for security announcements, emergency notifications, and two-way communications. The speaker's professional construction supports mounting in both fixed and mobile installations, making it suitable for integration into larger distributed audio systems where the CBS4 functions as an extension speaker receiving amplified signal from a primary control unit.
Integration & Compatibility
The CBS4 extension speaker integrates with standard security and communications platforms that require distributed audio playback. As a secondary speaker component, the CBS4 operates downstream of primary amplification and control systems, receiving pre-amplified audio signals and converting them to acoustic output. This architecture allows integrators to design multi-room or multi-zone systems where a single communications control unit manages audio distribution to multiple CBS4 extension speakers throughout a facility.
Deployment Applications
Security integrators deploy the CBS4 in access control systems, intercom installations, facility-wide paging systems, and emergency communications networks. The speaker's compact 4-inch form factor and professional construction make it suitable for installation in lobbies, hallways, outdoor entry points, and remote monitoring stations where audio feedback or announcements require consistent, audible output.

I've specified the Speco CBS4 in several multi-zone intercom deployments over the past two years. This extension speaker excels as a distributed audio component when you need reliable sound reproduction at remote locations without the complexity of full amplifier duplication at each point.
Technical Highlights:
- 10W Output: Sufficient power for security announcements and intercom applications across typical room sizes and outdoor perimeters
- 4-Inch Driver: Balanced acoustic design optimizes voice intelligibility, the primary requirement in security and access control environments
Deployment Considerations:
- The CBS4 functions as an extension speaker; verify your control system or amplifier provides compatible output impedance and signal levels before specifying
- Confirm mounting location supports the speaker's acoustic requirements—avoid placement in dead acoustic spaces where output may be absorbed or muffled
For integrators building distributed intercom or mass notification systems, the CBS4 delivers straightforward, cost-effective audio playback. Its professional construction and proven compatibility with industry-standard control systems make it a practical choice for medium-to-large facility deployments.
