3-1/4" Piezo Horn Tweeter Similar to KSN1005A

Our PZ1005 piezo tweeter provides the same performance as the original CTS KSN1005A, so you can bring your vintage speakers back to life at a fraction of the cost of our competitors.

Product Details

The PZ1005 is specifically designed and engineered to be a replacement for the very popular KSN1005A piezo tweeters from days gone by. Using a 22 mm ceramic piezo element, our piezo tweeters follow CTS' original recipe and are far superior to most look-alike piezos.

With a wide frequency range and ample power handling, this is also a prime candidate for new designs, especially if the crossover requirements must be kept to an absolute minimum.
