Audiotek AT-W450S 3.25" Titanium Super Tweeter

The Audiotek AT-W450S is a 3.25-inch titanium super tweeter designed to add upper-frequency output to a car audio system. It is intended for listeners building or upgrading systems that need more presence and detail in the high-frequency range. This listing is for one individual tweeter.

With a listed 1-inch titanium dome and 100 dB sensitivity, the AT-W450S is built for efficient high-frequency reproduction. Its specified 3,000 Hz to 25,000 Hz response range targets the upper portion of the audible spectrum. It is suited to systems using dedicated midrange speakers or other drivers for lower frequencies.

The AT-W450S is specified at 8 ohms and carries a listed 500-watt RMS rating. Careful amplifier matching and crossover setup are important when integrating a high-frequency driver into a multi-speaker system. Use an appropriate high-pass crossover so low-frequency content is not sent to the tweeter.

A die-cast aluminum frame provides a rigid mounting structure, while the aluminum voice coil and titanium dome are part of the driver’s high-frequency design. The unit is also listed with built-in tweeter protection and high-temperature-resistant construction. These details support use in demanding automotive audio installations when the system is configured correctly.

Its compact 3.25-inch overall diameter and 2.25-inch mounting depth help it fit into custom panels, door builds, dash installations, and other purpose-built locations. Spade terminals provide a straightforward speaker-wire connection point. For balanced results, pair it with compatible midrange drivers, suitable amplification, and properly configured crossover filtering.

Key Features

• 3.25-Inch Super Tweeter: Compact high-frequency driver for custom car audio installations.
• 1-Inch Titanium Dome: Designed for detailed upper-frequency reproduction.
• 3,000–25,000 Hz Response: Covers a specified high-frequency operating range.
• 100 dB Sensitivity: Supports efficient output from compatible amplification.
• Die-Cast Aluminum Frame: Provides a rigid structure for mounting.
• Tweeter Protection: Listed protection feature supports proper system use.

Design & Installation

The AT-W450S uses a die-cast aluminum frame, aluminum voice coil, and titanium dome assembly. Its aluminum-dome design and high-temperature-resistant construction are specified for automotive audio use. The compact magnet is listed at 2.125 inches in size and 5.4 ounces in weight.

Allow for the specified 2.25-inch mounting depth and 3.25-inch overall diameter before cutting a mounting location. Connect speaker wire to the spade terminals and use a suitable high-pass crossover or protected tweeter circuit; this driver should not be used as a full-range speaker. Confirm impedance compatibility and power settings with the amplifier and the rest of the system before installation.
