PZ1142Horn Drivers

Piezo Bullet Horn Driver Similar to KSN1142A

Our PZ1142 piezo tweeter provides the same performance as the original CTS KSN1142A, so you can bring your vintage speakers back to life at a fraction of the cost of our competitors.

Product Details

The PZ1142 is specifically designed and engineered to be a replacement for the very popular KSN1142A 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.

Standard 1-3/8" 18-TPI threads facilitate use with 1" horns. 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. 

Specifications: • Power handling: 60 watts RMS, 120 watts (internal protection circuitry dissipates up to 400 watts) • Frequency response: 1,800-30,000 Hz • SPL: 92 dB 1W/1m • Dimensions: Diameter: 2-7/16", Depth: 1-1/2".
