The digital clock radio that I bought for only $.99 has a bigger one (and makes a bigger shriek). :lol:
ok it seems the idea of a 100 khz range meter is not possible
there is alot of loudspeakers in any size, any shape and any....
then i call all them "speaker" i am not family with all names of speakers..
so let me know what kind of speakers are good for a range between 25 to 50KHz rather than a ultrasonic sensor?
