Audiotek ATW440P 3.8" Titanium Super Tweeter Pair

The Audiotek ATW440P is a pair of 3.8-inch car audio super tweeters designed to add dedicated high-frequency output to a component speaker system. Each unit is identified as an AT-W440 tweeter and is rated at 8 ohms with a listed 3,000 Hz to 25,000 Hz frequency response. They are intended for vehicle installations where existing speakers need added upper-frequency coverage.

This pair is suited to listeners building or refreshing a car audio system with separate midrange, bass, and high-frequency drivers. The included crossover capacitors support use as dedicated tweeters rather than direct full-range drivers. With a listed 99 dB sensitivity, the tweeters are specified to produce useful output from modest amplifier power when the system is set up appropriately.

The AT-W440 design focuses on the upper-frequency range, covering the detail, presence, and high-frequency information above its 3,000 Hz lower response limit. Its 1-inch super-tweeter element is designed to complement compatible midrange speakers rather than replace them. The 8-ohm nominal impedance should be considered when matching channels, passive components, and system wiring.

Construction details include an aluminum dome design, aluminum voice coil, and die-cast aluminum frame. The frame provides a rigid mounting structure, while spade terminals provide a straightforward connection point for speaker wiring. Built-in tweeter protection is also listed for each unit.

The ATW440P package includes two tweeters, crossover capacitors, and installation accessories for a paired high-frequency upgrade. Its 1-5/8-inch mounting depth and 3.75-inch overall diameter provide useful fitment references before installation. It can be used as part of a component system alongside properly filtered midrange speakers and a compatible amplifier or head unit.

Key Features

• Paired Super Tweeters: Includes two AT-W440 high-frequency drivers for stereo installation.
• 3,000–25,000 Hz Response: Covers the specified upper-frequency range for component systems.
• 8-Ohm Impedance: Supports matching with compatible amplifier channels and crossovers.
• 99 dB Sensitivity: Listed sensitivity supports efficient high-frequency output.
• Die-Cast Aluminum Frame: Provides a rigid structure for secure mounting.
• Crossover Capacitors Included: Helps route appropriate high-frequency content to the tweeters.

Design & Installation

The AT-W440 uses a die-cast aluminum frame, aluminum dome design, and aluminum voice coil. Each tweeter has a listed 2-3/4-inch magnet with a 5.4-ounce magnet weight. Spade terminals are provided for speaker-wire connection, and built-in protection is listed as part of the tweeter design.

Confirm available mounting space before installation: the listed overall diameter is 3.75 inches and mounting depth is 1-5/8 inches. Install the included crossover capacitors as part of the tweeter circuit and use the pair with compatible midrange or full-range speakers for a component-style system. Match the wiring and amplifier channel to the listed 8-ohm impedance, and avoid sending low-frequency content to the tweeters.
