Audio360 AD48TW 5.49" Super Tweeter

The Audio360 AD48TW is a high-frequency super tweeter designed to add upper-range detail to a car or marine audio system. It is intended for listeners building systems that need dedicated treble reproduction beyond what larger speakers or subwoofers provide. The requested configuration includes two AD48TW tweeters for left- and right-channel use.

Each AD48TW is rated at 4 ohms and listed with 2,500 watts maximum power handling, for 5,000 watts total maximum handling across the pair. Its 107 dB sensitivity rating indicates efficient output from comparatively modest amplifier power. The stated 2 kHz to 20 kHz frequency range focuses the driver on upper-midrange and high-frequency duties.

A phenolic diaphragm is used for the sound-producing element, while the voice coil uses CCAW construction. These materials are part of the driver design specified for this model. A 15.2-ounce magnet is also listed for each tweeter.

The AD48TW is suited to systems using separate low-, mid-, and high-frequency drivers rather than as a replacement for a full-range speaker. It can complement midrange speakers and subwoofers by handling the upper portion of the audible frequency range. Its wired connection format makes it appropriate for conventional amplified car-audio speaker wiring.

This model is listed for car and marine audio applications, giving installers flexibility when selecting a high-frequency driver for a vehicle or boat system. Proper system matching remains important because the 4-ohm load must be compatible with the amplifier channel and crossover arrangement. The product is listed as a super tweeter, so it should be integrated as part of a multi-driver system.

Key Features

• Super Tweeter Design: Adds dedicated high-frequency output to a multi-speaker audio system.
• 4-Ohm Impedance: Works with amplifier channels designed for 4-ohm speaker loads.
• 107 dB Sensitivity: Supports efficient high-frequency output with appropriate system power.
• 2 kHz–20 kHz Response: Covers upper-midrange and treble frequencies specified for the driver.
• Phenolic Diaphragm: Uses the specified phenolic material for the diaphragm assembly.
• CCAW Voice Coil: Features a copper-clad aluminum wire voice coil design.

Design & Installation

The AD48TW uses a phenolic diaphragm, CCAW voice coil, and a listed 15.2-ounce magnet. Its published overall size is 5.49 by 4.72 inches, placing it in the large-format super-tweeter category. The model is specified as a wired dynamic-driver tweeter for automotive and marine-oriented audio applications.

Mount the pair where their high-frequency output can be directed toward the listening area and where the 5.49 by 4.72-inch footprint can be accommodated. Connect each tweeter to an amplifier or speaker circuit compatible with a 4-ohm load, and use an appropriate crossover or high-pass arrangement so the driver operates within its listed 2 kHz to 20 kHz frequency range. Confirm available mounting clearance and system wiring before installation.
