Just got one £14.99 and it works on our 14 year old but he says its not that loud. So looking for a good outdoor wide angle tweeter.

Better push it up to 22 to 26 kHz around me, i can still hear 20 kHz, course when i was a teen i could hear 27 kHz. The ultrasonic intrusion detectors in some stores drove me nuts.
