Audiotek ATW520S 1.75" Titanium Super Tweeter

The Audiotek ATW520S is a 1.75-inch titanium super tweeter for adding dedicated high-frequency output to a car audio system. It is intended for systems that need clearer reproduction of upper-frequency detail beyond what larger speakers typically handle. This listing is for one tweeter.

With a stated frequency response of 3,000 to 25,000 Hz, the ATW520S is designed to cover the upper portion of the audible range. Its titanium diaphragm is paired with a die-cast aluminum frame for a purpose-built high-frequency driver assembly. The stated 100 dB/W/m sensitivity supports strong output with compatible equipment.

The ATW520S is rated at up to 1,400 watts maximum power. It is listed for 4- to 8-ohm system compatibility, making it suitable for integration into appropriately matched aftermarket speaker systems. A confirmed RMS power rating is not published in the available product information.

This super tweeter is a practical option for custom car audio installations using midrange speakers, component speakers, or other drivers that need dedicated treble reinforcement. It is not a full speaker replacement and should be used as part of a properly configured multi-speaker system. The included crossover capacitor supports high-frequency signal routing during installation.

For system upgrades, the ATW520S can be added where more upper-frequency presence is desired without changing the main midrange or bass drivers. Its compact 1.75-inch format is suited to installations where a dedicated tweeter location is available. Confirm mounting clearance, wiring polarity, and amplifier or crossover compatibility before installation.
