TOA Electronics 2-Way Weatherproof Coax Music Horn Speaker

Product Overview

The TOA CS-761 (CS-761B/CS-761W) is a 60 W 2-way coaxial horn speaker engineered for high-efficiency outdoor public address and background music applications. With IP66 weatherproof certification, 100 dB sensitivity, and selectable 70 V / 100 V transformer taps, it delivers clear, intelligible audio over wide coverage areas in demanding outdoor environments.

Product Description

The CS-761 uses a coaxial 2-way design — a 16 cm (6") cone woofer combined with a 2.5 cm (1") tweeter — providing wide frequency response from 100 Hz to 20 kHz. A crossover at 2.5 kHz ensures smooth transition between drivers, and the 90° horizontal × 80° vertical dispersion pattern covers medium-to-large outdoor areas efficiently from a single mounting point.

The built-in transformer accommodates both 70 V and 100 V distributed systems with selectable wattage taps (7.5 W, 15 W, 30 W, 60 W), allowing flexible integration into virtually any high-impedance PA system. An internal overload protection circuit safeguards the speaker from damage. The ABS resin enclosure with UV-resistant polyurethane paint and stainless steel mounting hardware carries IP66 certification — protected against dust ingress and high-pressure water jets from any direction.

Key Features

• IP66 weatherproof — Fully sealed against dust and high-pressure water jets; rated for permanent outdoor installation
• 60 W rated input — High power handling for broad-area outdoor public address
• 100 dB sensitivity — High efficiency for maximum SPL; 117 dB max SPL at 60 W / 1 m
• 70 V / 100 V compatible — Selectable transformer taps at 7.5 W, 15 W, 30 W, and 60 W
• 2-way coaxial design — 16 cm woofer + 2.5 cm tweeter with 2.5 kHz crossover for full-range intelligibility
• UV-resistant enclosure — ABS resin with polyurethane paint and stainless steel hardware for long-term outdoor durability
• Built-in overload protection — Internal circuit protects the speaker from thermal and electrical overload

Typical Applications

• Outdoor public address and emergency paging at transit stations, bus terminals, and airports
• Stadium concourses, sports facilities, and parking structures requiring high-SPL outdoor announcements
• Industrial facilities, warehouses, and manufacturing yards with demanding outdoor PA requirements
• Parks, outdoor plazas, and recreational facilities requiring wide-area background music and announcements
• School campuses, government facilities, and commercial properties with outdoor PA zones

Technical Specifications

Frequently Asked Questions

• What does IP66 protect against? IP66 means the speaker is fully dust-tight and protected against high-pressure water jets from any direction — suitable for permanent exposed outdoor installation in rain and wash-down environments.
• What voltage lines does the CS-761 support? Both 70 V and 100 V distributed lines, with selectable transformer taps at 7.5 W, 15 W, 30 W, and 60 W for each voltage.
• How does the coaxial design benefit audio quality? The 16 cm woofer and 2.5 cm tweeter share the same acoustic axis, providing consistent, intelligible sound across the 90° × 80° coverage pattern.
• Can it be installed near saltwater environments? TOA recommends avoiding locations near seashores or indoor swimming facilities without adequate ventilation, as salt air can accelerate bracket corrosion over time.
• What is the maximum SPL? 117 dB at 1 m with 60 W input — suitable for high-noise industrial, transit, and sports facility environments.
• What colors are available? CS-761B (black, RAL 9011) and CS-761W (white) — both share identical electrical and acoustic specifications.
