Piezoelectric tweeter for DIY speaker builds

This 80mm diameter piezoelectric tweeter is designed for hobbyists assembling their own speaker cabinets. The ABS housing measures 48mm in height with a 63mm diagonal diameter. It handles a rated power of 20W and a maximum of 100W, making it suitable for home audio-visual projects.

Simple two-wire connection

Installation requires connecting only the positive and negative terminals. The integrated color lights flash in multiple colours when wired to the same positive pole as the speaker, synchronising with the music signal. No additional accessories are included in the package.

Limited to high-frequency reproduction in passive

As a standalone piezoelectric tweeter, this unit covers only the upper frequency range and requires a separate woofer or midrange driver for full-range sound. It lacks a built-in crossover network, so external filtering is necessary to protect the driver and blend with other units. The ABS construction provides durability but does not offer magnetic shielding.

Questions about this item

How can I verify the tweeter is operating correctly after installation?

Connect the unit to an amplifier and play a test tone; the piezoelectric element should reproduce clear high frequencies up to its 20 W rated power without distortion.

What components are included and what must be sourced separately?

The package contains two 80 mm diameter speaker tweeters; crossovers, mounting hardware, enclosures and amplifier are not included.

Which power-rated version should I select for my build?

This model is offered only with a 20 W rated and 100 W maximum power specification; choose it when your amplifier delivers up to 100 W peak per channel.
