The TOA H-3 EX is a premium wide-dispersion wall-mount speaker from TOA's acclaimed Interior Design Series, engineered to deliver exceptional sound quality while seamlessly integrating with modern architectural aesthetics. Designed for commercial and residential applications where visual appeal is as critical as acoustic performance, the H-3 EX combines sophisticated styling with professional-grade audio engineering to provide an elegant solution for background music, paging, and distributed audio systems.

Featuring a sealed two-way enclosure with dual 4" cone woofers and a 1" neodymium dome tweeter, the H-3 EX delivers clear, balanced audio reproduction across a wide frequency range (100 Hz – 20 kHz). The speaker's broad 140° horizontal coverage pattern ensures even sound distribution throughout listening areas, minimizing dead spots and reducing unwanted reflections that can color the sound. This wide dispersion makes the H-3 EX ideal for installations requiring fewer speakers while maintaining consistent coverage.

Built with fire-resistant ABS resin construction and featuring a paintable grille for complete customization, the H-3 EX disappears into virtually any interior décor. The integrated step-down transformer supports both 70.7V and 100V distributed audio systems with multiple power taps (30W, 15W, 7.5W, 3.75W), plus direct 8Ω or 16Ω low-impedance connection for maximum installation flexibility.

For outdoor or high-humidity environments, the weather-resistant H-3WP EX variant offers IP-rated protection when installed under cover, extending the Interior Design Series' elegant aesthetics to patios, covered walkways, and semi-outdoor spaces.

Backed by TOA's industry-leading 5-year warranty and decades of commercial audio expertise, the H-3 EX represents the perfect balance of form and function for discerning integrators and property owners.

Frequently Asked Questions

Q: Can the H-3 EX be used outdoors? A: The standard H-3 EX is for indoor use only. For covered outdoor applications (patios, eaves, covered walkways), choose the H-3WP EX weather-resistant variant. Neither model is suitable for uncovered outdoor exposure.

Q: What's the difference between 70V and 100V settings? A: Both are constant-voltage distributed audio systems. 100V is common in Europe/Asia; 70.7V is standard in North America. Choose based on your amplifier's output. The H-3 EX supports both with multiple power taps on each.

Q: Can I paint the speaker grille? A: Yes! The grille is designed to be painted with latex or acrylic paint. Remove the grille before painting, apply light coats to avoid buildup in the perforations, and allow complete drying before reinstalling.

Q: How many H-3 EX speakers can I run on one amplifier channel? A: On 70V/100V systems, add up the wattage of all speaker tap settings. Keep the total at or below your amplifier's rated output. For example, a 240W amplifier can power eight H-3 EX speakers set to 30W each (8 × 30W = 240W).

Q: What mounting hardware is required? A: The H-3 EX mounts to a standard 2-gang electrical box (not included). The speaker includes the base frame and mounting screws. You'll need to supply the electrical box, wire, and wall anchors/studs for secure installation.

Q: How does the 140° coverage compare to other speakers? A: Most wall-mount speakers offer 90-120° coverage. The H-3 EX's 140° dispersion means broader coverage with fewer speakers needed, reducing installation cost and visual clutter.

Q: Can I use the H-3 EX for home theater surround sound? A: Yes, when connected via 8Ω low-impedance mode to a conventional home theater receiver. The H-3 EX works well as side/rear surrounds or height channels. Use the 8Ω or 16Ω setting (not the 70V/100V transformer taps).

Q: What's the expected lifespan? A: With proper installation and operation within rated specifications, the H-3 EX is designed for 15-20+ years of continuous commercial use. TOA's 5-year warranty reflects their confidence in long-term reliability.

Q: Does the speaker require a crossover or equalizer? A: No, the H-3 EX includes an internal passive crossover. However, optional DSP equalization (via TOA 900 Series modules or third-party processors) can optimize performance for specific room acoustics.

Q: What's the minimum amplifier power required? A: The H-3 EX is highly efficient (89 dB sensitivity). For background music, 5-10W per speaker is typically sufficient. For foreground audio or higher SPL requirements, use the full 30W rating.
