Overview

The Soundstream SPT.20 1" Aluminium Pro Audio Tweeters are engineered for extreme performance, delivering powerful, crystal-clear highs with impressive output. Designed as high-efficiency compression tweeters, they produce a commanding 350W peak and 175W RMS power handling, making them ideal for high-output systems that demand strong, detailed treble response. With a 4-ohm impedance and an outstanding 105dB sensitivity, these tweeters cut through even the loudest setups with clarity and precision.

High-Efficiency Pro Audio Performance: With a powerful 175W RMS (350W Peak) rating and an extremely high 105dB sensitivity, the SPT.20 produces loud, clean highs with minimal amplifier power. The 4-ohm impedance makes it compatible with most aftermarket amplifiers and high-output systems.

Wide Frequency Response: The wide 2kHz – 20kHz frequency response ensures bright, detailed reproduction of vocals, cymbals, and high-frequency instruments, making them ideal for systems focused on clarity and volume.

Aluminium Compression Design: The 1" aluminium diaphragm provides sharp transient response and enhanced durability under high output conditions. This pro-audio compression-style design delivers strong projection, making it suitable for SPL-oriented builds, show vehicles, Ute and outdoor audio setups.

Customisable Appearance: The SPT.20 includes four interchangeable coloured grilles, allowing you to match the tweeters to your vehicle’s interior theme or custom build aesthetic.

Built with a durable 1-inch aluminium diaphragm, the SPT.20 offers crisp, dynamic sound reproduction across a wide 2kHz – 20kHz frequency range. Whether you're building a pro audio-style system or upgrading for stronger stage presence and vocal projection, these tweeters are designed to deliver sharp articulation and extended high-end performance without compromise.

Installation is straightforward thanks to the quick disconnect terminals and a compact 2.25-inch mounting depth, making them easy to integrate into a variety of custom setups. To match your build’s style, the SPT.20 includes four interchangeable colour grilles, allowing you to customise the look while maintaining serious acoustic performance.
