Appearance


Basin/Frame:A square, rounded-corner black metal (or high-strength engineering plastic) basket frame is used, providing a robust structure and effectively 

suppressing resonance. Standard round screw holes at the four corners of the basket frame facilitate secure mounting to the cabinet or equipment panel.

Dust Cap:A silver or light gray circular dust cap with a finely brushed texture is located in the center of the diaphragm. Its main function is to prevent dust from 

entering the magnetic gap, and it also participates in the reproduction of high-frequency sounds.

Suspension: A black, corrugated rubber suspension ring connects to the edge of the cone. It supports the diaphragm and allows for precise piston movement; 

its compliance (softness) directly affects the low-frequency response.


Features


Full-range/Mid-range Reproduction: Judging from the diaphragm size and structure, this unit is designed to reproduce mid-range and some high-frequency 

sounds, and can be used as a full-range unit with clear vocal reproduction.

Rugged and Easy to Install: The square frame provides excellent stability and makes installation and positioning very convenient, offering high compatibility.

Durable Design: The rubber suspension has a long lifespan and can adapt to various environments; the robust frame ensures long-term reliability.

High Efficiency: The optimized magnetic circuit and diaphragm design ensure high electro-acoustic conversion efficiency.


Advantages


Clear Vocals: Its excellent mid-frequency response ensures clarity and realism in both spoken and main musical tones.

Easy Installation: The standardized square design and mounting holes simplify the integration process.

Stable Performance:Robust construction and high-quality materials guarantee reliable performance and a long service life.


Instructions


During installation, ensure all four screws are tightened evenly diagonally to prevent the frame from twisting. Twisting the frame can cause friction between 

the voice coil and the magnetic gap (commonly known as "coil rubbing"), resulting in permanent damage.

Power Matching: Always use within the rated output power range of the compatible amplifier (or equipment). Overloading is strictly prohibited to prevent 

instantaneous burnout of the voice coil.

Handle with Care: Avoid pressing the dust cap and diaphragm with your hands to prevent deformation.


Application Scenarios


Car audio systems: Midrange or full-range speaker units installed in car doors.

Public address systems: Background music and voice announcement systems in shopping malls, schools, and offices.

Home multimedia equipment: Computer multimedia speakers, portable Bluetooth speakers, etc.

Professional audio equipment: Midrange units in conference system speakers and stage monitor speakers.

Communication equipment: Handpiece speakers in walkie-talkies and telephones.
