Appearance


Frame/Seat Stand: An octagonal frame made of black plastic with chamfered corners for a refined appearance. Standard screw holes at the 

four corners facilitate secure installation. This non-circular stand helps achieve a more stable fixation in limited spaces.

Cone: The core component is a round, gray-black cone with a finely textured or matte finish.

Suspension: Clearly visible in the side view is a dark-colored ring suspension around the cone edge, supporting the diaphragm and allowing 

for precise piston movement.

Magnetic Circuit System: The side view clearly shows a large, black cylindrical magnetic circuit system (typically a ferrite magnet) at the rear. 

Its size indicates good power handling and sensitivity.

Terminals: On the side of the magnetic circuit system, two silver metal pins serve as solder terminals for connecting audio signal cables.


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 likely be used as a full-range unit, with outstanding vocal performance.

High-Efficiency Magnetic Circuit Design: The large magnetic circuit system ensures high electro-acoustic conversion efficiency.

Compact and Easy to Install: The unique octagonal plastic frame reduces overall weight while providing a stable mounting method and high compatibility.

Durable Construction: The plastic frame effectively suppresses resonance, and the rubber suspension has a long lifespan.


Advantages


Clear vocals: Excellent mid-range response ensures clarity of speech and key musical tones.

Easy installation: Standardized mounting holes and lightweight design simplify the integration process.

Stable performance: Robust magnetic circuitry and a rational structural design guarantee reliable performance.


Instructions


During installation, ensure even force is applied to all four mounting ears to prevent frame twisting, which could cause friction between the voice 

coil and the magnetic gap (coil rubbing).

Power Matching: Always use within the rated power range of the compatible amplifier. Overloading is strictly prohibited to prevent burning out the voice coil.

Careful Soldering: When connecting signal cables to metal pins, solder quickly to avoid overheating and damaging internal connections.


Application Scenarios


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

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

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

Communication equipment: Handsets or hands-free speakers for landline telephones and walkie-talkies.

Musical instrument amplification: Electronic keyboards, guitar practice amplifiers, etc.
