STXAudio STX-580TW 2.94" Super Tweeter

The STXAudio STX-580TW is a 2.94-inch super tweeter designed to add dedicated high-frequency output to a car-audio or professional audio speaker system. It is intended for listeners building a more detailed top end than a full-range or factory speaker setup can provide alone. With a 4-ohm nominal impedance, it is suited to systems using compatible external amplification or speaker channels.

This super tweeter is specified for a 3 kHz to 20 kHz frequency range, covering upper-frequency material such as vocal presence, percussion detail, and instrument overtones. Its 103 dB sensitivity rating indicates efficient output relative to input power. The result is a focused high-frequency driver meant to complement midrange and bass drivers rather than replace them.

The STX-580TW carries a 500-watt maximum power rating. Because a maximum rating is not the same as continuous RMS power handling, amplifier matching should be based on the amplifier's clean output, system crossover settings, and the complete speaker system. This approach helps keep the tweeter operating within an appropriate filtered frequency range.

A titanium diaphragm is used for the high-frequency radiating surface, while the voice coil uses CCAW construction. These confirmed design details support a lightweight moving assembly for upper-frequency reproduction. The compact 2.94-inch format is useful where installation space is limited.

The STX-580TW is a practical addition for custom car-audio builds that need a dedicated high-frequency driver. It can be integrated with compatible mids, woofers, and an appropriately configured crossover or high-pass filter. Confirm available mounting space, system impedance, and amplifier configuration before installation.

Key Features

• 2.94-Inch Super Tweeter: Compact high-frequency driver format for custom audio installations.
• 500W Maximum Power: Supports systems designed for substantial peak power capability.
• 4-Ohm Impedance: Matches many common car-audio amplifier and speaker configurations.
• 103 dB Sensitivity: Provides efficient output from a relatively compact driver.
• Titanium Diaphragm: Uses a lightweight, rigid diaphragm material for treble reproduction.
• CCAW Voice Coil: Uses copper-clad aluminum wire in the voice-coil construction.

Design & Installation

The STX-580TW uses a compact super-tweeter layout with a titanium diaphragm and CCAW voice coil. Its 2.94-inch size helps it fit into installations where larger high-frequency drivers may not be practical. The product is specified as a super tweeter, so it is intended to work as part of a multi-driver system.

Install the tweeter securely in a location that preserves clearance and directs high-frequency output toward the listening area. Use a compatible 4-ohm amplifier channel or speaker network, and protect the driver with an appropriate high-pass crossover setting; no crossover frequency or included crossover is confirmed. Verify the mounting method, supplied accessories, and wiring requirements with the selling source before beginning the installation.
