Valcom SX15-T 15-Watt Paging Horn Speaker
The Valcom SX15-T is a 15-watt paging horn engineered for high-efficiency voice paging, emergency alert delivery, and audible signaling across industrial, commercial, and outdoor environments. Built into the SX-Series platform, the SX15-T combines acoustic performance with rugged deployment flexibility, supporting both wall and ceiling mounting configurations. This accessory integrates into facility-wide distributed audio and paging systems where clear, intelligible voice communication and emergency notification are critical.
Key Features
- 15-Watt Output Power: Delivers sufficient acoustic energy for medium to large coverage areas in industrial and commercial settings. This wattage level balances clarity and reach without requiring oversized amplifier infrastructure, reducing overall system cost and complexity.
- High-Efficiency Horn Design: SX-Series architecture optimizes sound projection and clarity for voice paging applications. The horn geometry ensures voice intelligibility across large open spaces like warehouses and production floors, even in environments with background noise.
- Voice Paging Capability: Engineered for clear, intelligible voice reproduction across facility-wide announcement systems. Supports both automated alert playback and live microphone input for immediate personnel communication during emergencies or shift changes.
- Emergency Alert Function: Generates loud, attention-grabbing alert tones and emergency notification signals. Critical for life-safety announcements in warehouses, parking facilities, and industrial plants where response time is essential.
- Ringing and Signaling: Produces audible ringing signals for call signaling and alerting purposes, extending the horn's utility beyond voice paging to include facility-wide alerting infrastructure.
- Dual Mount Flexibility (Wall and Ceiling): Supports both wall and ceiling mounting configurations, enabling deployment in diverse facility layouts. Wall mounting suits administrative areas and control rooms; ceiling mounting provides optimal coverage in large open spaces and warehouses where sightlines are obstructed by inventory or equipment.
- Indoor and Outdoor Rated: Constructed for reliable operation in both protected interior environments and exposed exterior settings. This rating eliminates the need for separate indoor and outdoor horn selections, simplifying procurement and standardizing deployment across perimeters, loading docks, and parking facilities.
- Microphone Input Support: Compatible with microphone input, enabling direct voice input and live paging capability. Allows facility operators to broadcast urgent announcements without relying on pre-recorded content.
- Gray Finish: Neutral gray color blends into industrial and commercial facility aesthetics without drawing attention or requiring custom enclosures.
- Industrial-Grade Construction: Designed for durability in demanding warehouse, parking lot, stadium, and plant environments where equipment must withstand vibration, temperature extremes, and frequent use.
Deployment Applications
The SX15-T addresses facility-wide paging needs across multiple vertical markets. In warehouses and distribution centers, the horn provides clear announcements to personnel across large open spaces and elevated work areas. Parking facilities benefit from the horn's outdoor-rated design and high output for safe egress communication and emergency evacuation directions. Stadium and arena installations use the SX15-T for crowd management announcements and emergency notifications. Industrial plants leverage the horn's efficiency and durability for production floor paging, shift changes, and safety alerts. The 15-watt power level and high-efficiency horn design ensure adequate coverage without requiring excessive amplifier infrastructure, making the SX15-T suitable for both new system installations and upgrades to existing distributed audio systems.
Integration & Compatibility
The SX15-T integrates with standard facility paging and distributed audio systems. The horn accepts microphone input, enabling both automated alert playback and manual live paging from control stations. The dual mounting capability (wall and ceiling) simplifies system design across different facility zones, from administrative areas to production floors to outdoor perimeters. The gray finish matches common industrial color schemes, supporting clean facility integration. When planning a multi-horn deployment, calculate coverage area based on the 15-watt output and facility acoustics — open warehouses require fewer horns than compartmentalized industrial buildings with sound-absorbing materials.
When to Consider Alternatives
If your facility requires higher output power for exceptionally large or noisy environments, evaluate higher-wattage horns in the Valcom SX-Series family. Conversely, for smaller spaces or lower-noise indoor areas, lower-wattage options may provide adequate coverage at reduced cost. Consult acoustic load calculations specific to your facility layout and ambient noise levels before finalizing horn selection.
Frequently Asked Questions
Q: What is the SX15-T (often searched as SX15 T) primarily used for?
A: The SX15-T is designed for voice paging, emergency alerts, and audible signaling in warehouses, parking facilities, stadiums, and industrial plants. It supports both live microphone input and automated alert playback across distributed audio systems.
Q: Can the SX15-T be mounted on both walls and ceilings?
A: Yes. The SX15-T supports both wall and ceiling mounting configurations, allowing flexible deployment across different facility zones and layouts.
Q: Is the SX15-T suitable for outdoor environments?
A: Yes. The SX15-T is rated for both indoor and outdoor operation, making it suitable for exposed exterior deployments such as loading docks, parking lot perimeters, and facility exteriors.
Q: Does the SX15-T work with microphone input?
A: Yes. The SX15-T supports microphone input, enabling live voice paging directly from control stations or handheld microphones for emergency announcements.
Q: What power level does the SX15-T deliver?
A: The SX15-T provides 15 watts of output power, which balances acoustic reach with efficient amplifier load for medium to large coverage areas in industrial and commercial settings.
Q: How does the gray finish affect facility aesthetics?
A: The neutral gray color blends into standard industrial and commercial facility color schemes, minimizing visual contrast and eliminating the need for custom enclosures or additional cosmetic modifications.

The SX15-T is a straightforward workhorse — 15 watts is the right power level for most industrial facility deployments. It's not oversized (which saves on amplifier cost), and it's not undersized (which avoids coverage dead zones). The dual wall/ceiling mount flexibility is what you actually deploy around, and the fact that it handles both indoor and outdoor environments without requiring separate SKUs simplifies procurement and inventory management.
Technical Highlights:
- 15-Watt Output Power: Sufficient for medium to large spaces without oversizing amplifier infrastructure. In a 50,000 sq ft warehouse with standard 12-foot ceilings, a single SX15-T positioned centrally covers most production areas; larger facilities simply add additional horns and branch the amplifier output.
- High-Efficiency Horn Design: The SX-Series architecture prioritizes voice intelligibility in noisy environments. Warehouses with forklifts, machinery, and dock activity benefit measurably from the horn's acoustic design — announcements remain clear even at 75–80 dB ambient noise.
- Microphone Support: Direct mic input means emergency announcements don't depend on pre-recorded content. Shift supervisors and facility managers can broadcast immediate safety alerts without delay.
Deployment Considerations:
- Ceiling mounting in large open spaces is ideal for coverage uniformity, but confirm structural mounting points and conduit routing before installation. Avoid mounting directly above equipment where vibration or heat might degrade connections.
- Outdoor ratings cover rain and dust, but extreme salt-spray environments (coastal facilities) may require periodic inspection and corrosion-preventive maintenance on mounting hardware.
- The 15-watt level assumes a quality amplifier output and proper speaker wiring gauge (typically 16 AWG or heavier for runs over 50 feet). Undersized wire introduces impedance mismatch and reduces actual acoustic output.
The SX15-T fits neatly into warehouse, parking, and stadium deployments where voice clarity and emergency alert capability are non-negotiable but budget constraints prevent oversized multi-horn arrays. Pair it with a commercial-grade amplifier and you have a reliable, maintainable paging backbone.
