Content Summary : 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 features a magnetic circuit (employing a neodymium magnet) that 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 or 16 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.
