Looking for a circuit design (transmitter?) that will drive tweeters in the 20,000-40,000 Hz range. Need to power sound in excess of 50'linear feet. Am not quite sure of the questions I should be asking but I need a device (design) that is similar to "bark stopper" or "yard guard" with more power. I am seeking to blanket an area with hi freq. noise at irregular intervals, prefer sound actuated design but any help appreciated. Please mail me if I can clarify this for anyone. Remove "nospam". thanks RC
