PZ1188Horn Drivers

Piezo Horn Driver Similar to KSN1188A

Our PZ1188 piezo driver provides the same performance as the original CTS KSN1188A, so you can bring your vintage speakers back to life at a fraction of the cost of our competitors.

Product Details

The PZ1188 is specifically designed and engineered to be a replacement for the very popular KSN1188A piezo horn drivers 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. This 100 watt driver incorporates advanced protective circuitry which allows it to be used at power levels of up to 400 watts.

Specifications: • Power handling: 400 watts max • Frequency response: 800-20,000 Hz • SPL: 93 dB 1W/1m • Dimensions: Diameter: 3-7/8", Depth: 3".
