Review on Performance Piezo Tweeters Audio Frequency by Solomon Inks

I really used these super tweeters for my home theater! You sound super cool! Especially when I play soft jazz! Chris Botti Blueray. The highs are incredibly accurate! 30,000 Hertz. Gives a more realistic sound to a jazz concert. When I hear the drummer, his cymbals sound so loud and clear! Chris' trumpet is amazing! Now I'm definitely buying more of these 30,000 Hz super tweeters for my car. Highly recommended ! And they cost less than $20. Efficiency 94dB. I bought 3 pairs to fit Polk's front and center audio systems. I am very happy with them. This is theft!
