I'm looking for a high-powered ultrasonic transducer impedance-matched
to the atmosphere (not to a steel bucket).  Do some of the high-end
tweeter elements operate reasonably efficiently out to 40 or 50 kHz?
Any clues on achieving 50W or so of acoustic power at 40 kHz cheaply
would be greatly appreciated.  I'll even summarize if I get any
interesting suggestions.
