Review on Performance Piezo Tweeters Audio Frequency by Gavin Ghram
Works well so far.: Coaxial speakers
These tweeters will be the output side of my 800 watt anti-bark dog behavior change system because my neighbor's dogs bark all night when the air is moving. They work very well together with the DROK signal generator. At 23 kHz I hear nothing at all. Frequency response in the audible range is fine, but I'm looking at things above human hearing. The only sound from it when the system is on is a click from the speaker. Now you need to take the amplifier and solder it!
- Sturdy construction
- Poorly thought out
