Shock !!!!! Are they kidding us ??? Wherever I put them.. (Well, such tweeters were being produced by Sony at least 15 years ago..) I tried them on the expensive speakers of the house to temporarily cover the hole in the burnt tweeter of the Energy XL 26 and it plays at a higher level than the unattainable Canadian tweeters of Manisia. Concealment?? Alright !!! Clarity frequencies, sensitivity to low and high intensities !!! What's inside, guys ??? In the PC, in the car ??? They kill... In the car, I installed a 3.2mf capacitor, not to prevent them from burning due to low frequencies, which is not a joke, but to reduce the volume a bit, because I placed them on the driver and passenger columns
