2. GENERAL DESCRIPTION
TOA's H-1 is a cylinder-shaped, small flush-mount 2-way speaker featuring high sound quality.
3. FEATURES
• The H-1 Speaker System features, flush-mount speaker design with a rotatable cylinder-type enclosure. The
speaker's smooth curved surface allows it to blend in with the interiors of most modern buildings.
• The speaker's small (8 x 5 cm) woofer featuring high input capacity ensures powerful sound reproduction.
• The one-inch balanced dome tweeter features ferro-fluid to ensure superb transient response characteristics
for clear, high frequency sound output and high power-handling capabilities.
• The speaker's 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.
• The H-1 Speaker System is designed with an emphasis on installation ease and safety, as well as easier
conduit wiring when an electrical box is installed.
• The cylinder-shaped speaker's mounting angle can be easily adjusted for up to ±45 degrees rotation.
• A built-in matching transformer permits the speaker to be used for both high- and low-impedance
applications. For low-impedance applications, either the 4 Ω or 16 Ω terminal can be selected. Impedance
can be easily changed from outside the unit.
• Detachable screw terminals facilitate connection. Dual positive and negative terminals also facilitate bridge
connections.
• Both the speaker enclosure and Trim Piece are made of fire-resistant ABS (UL Standard 94: V-0 Grade).
• All external parts have been specially selected for ease of refinishing and repainting.
