Appearance


Diaphragm system:

Cone: The core component is a black cone-shaped diaphragm, which may be made of polypropylene (PP), paper-based composite materials or carbon fiber mixture. This dark material usually has good internal resistance properties, which helps reduce sound coloration and makes the sound purer.

Suspension: The edge of the cone is connected to a wide, corrugated black rubber rim. This design provides a long-stroke movement space for the diaphragm, which is beneficial to improving bass performance and power handling capabilities.

Magnetic circuit system: From the side view in the second picture, you can clearly see the relatively large magnetic circuit system at the rear of the basin frame (usually ferrite or high-performance neodymium magnets). The larger magnet volume indicates that this speaker has higher sensitivity and good dynamic response.


Features


Full-band sound reproduction: Judging from the diaphragm size and suspension design, this unit is designed to cover a wide frequency range and can be used as a full-range speaker, working independently without a crossover.

Long-stroke design: The wide rubber suspension allows the diaphragm to have a larger front-to-back displacement, which means it can push more air, thereby producing a more substantial and elastic bass.

High efficiency and high power handling: The powerful magnetic circuit system ensures high electro-acoustic conversion efficiency and the ability to carry greater input power.

Low-distortion performance: High-quality diaphragm materials and sturdy baskets work together to reduce unnecessary vibration and distortion.


Advantages


Precise sound and low distortion: The reinforced rib design makes the mid-low frequency performance particularly strong and clear, making the sound less likely to be muddy.

Strong power carrying capacity: The solid structure and large magnetic circuit enable it to withstand large input power.

High durability: The metal basin frame and rubber rim ensure long life and reliability of the product in various environments.


Instructions


Correct installation: When installing, be sure to tighten the four screws diagonally evenly to avoid distortion of the basin frame. Once deformed, it can easily cause friction between the voice coil and the magnetic gap (rubbing ring), causing permanent damage.

Impedance and power matching: It needs to match the output impedance and power of the power amplifier. Overload use is strictly prohibited, otherwise the voice coil will be burned instantly.

Handle with care: Avoid pressing the diaphragm with your hands to prevent deformation or damage to the voice coil and centering piece.


Application Scenarios


High-quality full-range speakers: used for desktop HIFI speakers and background music speakers that require a simple system and pursue the naturalness of human voices.

Car audio: As the main speaker on the car door, it provides comprehensive sound coverage.

Stage Monitor: As a small stage monitor speaker unit, it allows musicians to hear their own performances clearly.

Professional broadcasting and conference systems: used for public broadcasting or conference speakers that require high speech clarity.


FAQ


Q1: What is your MOQ?

A: Our standard MOQ is 100 units for regular models. We can offer a lower MOQ for pilot orders, but the unit cost will be higher.


Q2: Can we customize the color or material of the speaker? 

A: Yes. Color and material customization is available for OEM/ODM orders. Please contact us with your specific requirements for a quotation.


Q3: Do you provide ODM/OEM services?

A: Yes, we specialize in ODM and OEM services. We can design and produce speakers according to your technical specifications or design drawings.


Q4: How long does it take to develop a new product?

A: The development time depends on the complexity. It typically takes 4-8 weeks for a new design, including prototyping and testing.


Q5: What are your payment terms? 

A: We commonly accept T/T (Bank Transfer). For new customers, 50% deposit is required to start production, and the balance 50% before shipment.


Q6: Can I mix different products in one container? 

A: Yes, mixed orders are welcome. This is a cost-effective way to import. We will provide a detailed packing list for each product.
