Appearance


Front (combined two pictures): The core is a smooth black hemispherical diaphragm (dome tweeter design), which can effectively improve high-frequency response and diffusion. The diaphragm is surrounded by a wide black rubber suspension, which provides good compliance and linear stroke. The outermost layer is a black square basin rack.

Installation method: There is a metal spring buckle on each of the two opposite sides of the basin rack, which is used to directly snap the unit into the square opening of the equipment panel, making installation quick and easy. The other two corners of the basin frame also have a circular mounting hole, which can be used as an auxiliary fixation or as the main fixation with screws.

Connection method: There are two metal sheet-shaped terminals on the side of the basin frame for welding or plug-in connection.


Features


Dome diaphragm design: Helps improve high-frequency response, making the sound clearer and more delicate.

Quick installation structure: The unique spring buckle design allows for quick installation and removal without tools, greatly improving production efficiency.

Robust support: The rubber suspension is durable and stable in performance, ensuring linear motion of the diaphragm under high power.

Dual installation options: You can use either the convenient spring buckle or traditional screw installation for great flexibility.


Advantages


Extremely simple installation: The spring buckle is the biggest advantage, making batch assembly and maintenance extremely simple.

High-frequency clarity: Dome diaphragms usually provide better high-frequency extension and resolution.

Space efficient: The square basin rack saves internal space.


Instructions


Installation: Align the speaker unit with the pre-opened square hole on the equipment panel, and press hard until the four spring buckles shrink and then pass through the panel and pop open, then they can be firmly stuck. To be sure, you can also fix it with screws through the other two round holes.

Connect: Snap the wire's tab connector into the metal terminal on the side, or solder the wire directly to the terminal.

Note: Avoid pressing the center of the diaphragm during installation to prevent deformation.


Application Scenarios


Car audio: mid-range and high-pitched units on car door panels and dashboards, the spring buckles are very suitable for quick installation in small spaces.

Multimedia speakers: tweeter units for computer speakers and Bluetooth speakers.

Public address system: ceiling speakers, wall-mounted speakers.

Consumer electronics: Portable radios, sound units for smart home devices.
