Speco Technologies SP5MAT 5.25" 25/70V Speaker with Backbox

Speco Technologies SP5MAT 5.25" Speaker with Backbox

Overview

The Speco Technologies SP5MAT is a 5.25-inch surface-mount speaker system designed for commercial security, paging, and audio distribution applications. This unit combines a full-range speaker driver with an integrated backbox enclosure, delivering 25V and 70V constant-voltage output options. The SP5MAT serves as a cost-effective solution for installers requiring reliable audio reproduction in multi-zone installations, public address systems, and integrated security deployments.

Key Features

• 5.25-inch Speaker Diameter: Balanced acoustic performance suitable for medium-coverage areas and commercial environments
• Dual Voltage Output: 25V and 70V constant-voltage operation enables flexible transformer-based configurations and network integration
• Integrated Backbox Enclosure: Factory-assembled backbox reduces installation labor and ensures acoustic consistency
• Surface-Mount Design: Direct mounting capability for drywall, concrete, or suspended ceiling applications
• Commercial-Grade Construction: Built for demanding installations where reliability and consistent performance are required
• Full-Range Audio Reproduction: Supports voice paging, alarm tones, and music distribution across networked security systems

Integration & Compatibility

The SP5MAT integrates seamlessly into legacy and modern security systems leveraging 25V and 70V distributed audio architectures. Its constant-voltage design allows for multiple speakers to be connected in series or parallel configurations, depending on transformer impedance matching and system topology. The unit is compatible with analog audio amplifiers, security control panels with audio output modules, and IP-based audio gateways that support traditional voltage-output protocols. Integration with VMS platforms requiring secondary audio distribution, evacuation announcements, and multi-floor paging requires appropriate amplifier interface hardware.

Package Contents

The SP5MAT includes the speaker driver, integrated backbox enclosure, and mounting hardware. Installation requires standard electrical connections to 25V or 70V amplifier output terminals and mechanical fastening to the wall, ceiling, or structural support surface.

Jerry Tildsen

I've specified the Speco SP5MAT in distributed audio systems for campus security, retail, and government facilities. The integrated backbox saves considerable installation time compared to field-assembled speaker and enclosure combinations, and the 5.25-inch driver strikes a practical balance between coverage area and acoustic output for typical commercial deployments.

Technical Highlights:

• Voltage Flexibility: Dual 25V/70V operation accommodates both older analog amplifier infrastructure and modern constant-voltage distribution systems without additional interface hardware
• Integrated Backbox: Eliminates field assembly variability and reduces acoustic anomalies caused by poor enclosure-to-speaker coupling

Deployment Considerations:

• Confirm amplifier output impedance and voltage rating before installation; transformer tap configuration directly affects speaker output level
• Plan wire routing and termination points during system design; constant-voltage systems require proper gauge cabling for runs exceeding 200 feet to minimize signal loss

The SP5MAT is a proven choice for multi-zone audio in security-integrated facilities. Specify it confidently when your design calls for standard constant-voltage speakers and you want to minimize installation time and field assembly risk.
