2. GENERAL DESCRIPTION
TOA's H-3 and H-3WP are wall-mounted 2-way speakers featuring wide horizontal dispersion.
The H-3 is designed for indoor use, and the H-3WP is designed for outdoor use.
Note: Protect the H-3WP from rain when installing. (Refer to p. 10 "Waterproofing the base frame.")
3. FEATURES
Smooth curved surface blends in with the interiors of most modern buildings.
Wide horizontal dispersion covers wide areas when mounted on the wall.
Two 10 cm woofers feature a neodymium magnet which ensures powerful, low distortion low-frequency
sound reproduction.
2.5 cm soft dome tweeter also employs a neodymium magnet for clear, low distortion high-frequency sound
reproduction and high power-handling capability.
Built-in crossover network circuitry features sharp cut-off characteristics that realize uniform energy radiation
while suppressing unwanted input signals to the woofer or tweeter.
Two lock tabs secure the enclosure to the supplied base frame. The base frame can be mounted directly to
a 2-unit electrical box.
A built-in matching transformer permits the speaker to be used for both high- and low-impedance
applications. For low-impedance applications, either the 8 terminal or 16 terminal can be selected.
Impedance can be easily changed from outside the unit.
Detachable input connectors with dual positive and negative terminals for bridge connections.
Enclosure is made of fire-resistant ABS resin (UL Standard 94V-0 Grade).
Front grille is specially designed for ease of refinishing and repainting.
4. HANDLING PRECAUTIONS
To clean, wipe the unit with a dry cloth. When the unit gets very dirty, use a cloth damped in a neutral
detergent. Never use benzine, thinner or chemically-treated towel, as this could damage the unit's form or
finish.
• Avoid using the H-3WP speaker on the beach because the speaker's life can be greatly shortened by sea
breezes.
