[. . . ] Yorkville's ingenious self-resetting PTCTM high frequency protection circuit protects the high frequency components used in the C190 / C190W. PTCTM offers serious advantages over protection schemes used in many loudspeaker cabinets. While always present in the signal path, remains inaudible until it becomes necessary for it to react, at which point it effectively reduces output to the horn, protecting it from damage due to excessive power input or signal distortion. Unlike a breaker it does not require a physical reset to allow signal back to the horn driver, and unlike a bulb or fuse, does not need to be replaced if the circuit is tripped, and the fuse is blown, making it the ideal high frequency protection scheme for an installation loudspeaker. The rugged 3/4-inch MDF cabinet is available in either a white (C190W) or black (C190) paintable finish. Nine integrated 3/8-inch flypoints allow the C190 / C190W to be flown easily and on virtually any angle without modification to the speaker. [. . . ] An all-metal grille protects the loudspeaker components while the all-metal input plate supports both 1/4-inch and binding post connectors.
