## Overview

The Piezoelectric Speaker KSN 1025A is a 7-inch piezo ceramic tweeter featuring a 2x6 inch exponential horn with 90° horizontal dispersion. It boasts a high impedance over 400 ohms at 1kHz, ensuring no extra amplifier load and eliminating the need for a crossover. With a frequency response from 1 kHz to 40 kHz, 92dB sensitivity, and 75W max power handling, it delivers efficient, crisp high-frequency sound ideal for surround sound systems. Its flush mount design and durable materials make it a professional-grade audio component built for longevity and superior acoustic performance.

## Description

The 2 x 6 inch exponential horn has full 90 included angle horizontal dispersion. With an impedance of over 400 ohms at 1kHz, and still above 20 ohms at 40 kHz, the piezo ceramic speaker presents no added load to the amplifier and rejects low frequency power without requiring a crossover network. Electrically, these piezo ceramic speakers appear as 0.3 mfd capacitors and exhibit high efficiency ( 40 - 50% ) in converting electrical energy into acoustical energy.
