ZEH Audio is China’s top expert, manufacturer, and supplier of loudspeakers. The company mainly produces a variety of high-end loudspeakers, audio speakers, full-range speakers, subwoofers, Coaxial speakers, To meet your loudspeaker needs, we offer customization services as follows:
When an audio signal enters the speaker system, the crossover directs different frequency ranges to the appropriate drivers. The woofer or midbass driver reproduces the body and impact of the sound, while the tweeter delivers speech clarity, instrument overtones, and high-frequency detail. Together, they create a fuller and more balanced sound.
A coaxial speaker is a combined loudspeaker system in which two or more drivers covering different frequency ranges are mounted along the same central axis. A typical design places a tweeter at the center of a woofer or midbass driver, allowing different frequency ranges to radiate from nearly the same point.
Compared with a component speaker system in which the tweeter and woofer are installed separately, a coaxial speaker provides wider frequency coverage within a limited installation space. It also reduces the number of separate speaker units, helping simplify product design and assembly.
All coaxial speakers are available in flexible configurations to suit your product structure, enclosure design, amplifier parameters, target sound quality, and mass-production requirements.
Customizable parameters: size, shape, height, mounting hole pattern, impedance, rated power, magnet, diaphragm, crossover frequency, mounting method, and wiring connection. Speaker grilles available on request.
The ZEH engineering team provides full supporting solutions: speaker selection, enclosure matching, sample development, plastic/metal housing , PCBA, acoustic tuning, and reliability validation — streamlining assembly, improving acoustic integration, shortening development cycles, and ensuring stable acoustic performance, assembly fit, and batch-to-batch consistency.
ZEHSMAUDIO can adapt an existing speaker platform or develop a modified structure based on your installation space, sound target, electronics, enclosure and production requirements.
We review your housing dimensions and mounting structure before selecting the frame and magnetic circuit.
Round, oval, rectangular and low-profile frames can be adapted to internal ribs, PCB positions and assembly methods.
Speaker parameters are evaluated together with the amplifier, enclosure, listening distance and required sound performance.
Diaphragm, surround and magnet materials are selected according to the target sound, environment and cost requirements.
The project can include the enclosure, grille, wiring, connector, sealing components and amplifier matching.
Automotive speaker performance depends on how the speaker drivers, mounting structures, amplifiers, and vehicle acoustics work together. For OEM/ODM projects, ZEH combines acoustic design, mechanical customization, and supporting manufacturing services to help your products meet sound quality, installation, and volume production requirements.
Based on the available space in different vehicle models, dashboards, and other mounting locations, we evaluate speaker outer diameter, mounting depth, basket shape, magnet size, and mounting hole layout. We also provide matching brackets, grilles, and connection options to help reduce mechanical interference and subsequent assembly adjustments.
Based on amplifier output, impedance requirements, listening distance, and the desired sound, we coordinate rated power, sensitivity, frequency response, and distortion specifications to suit the intended in-vehicle audio system. In addition to speaker drivers, we can provide plastic or metal enclosures, grilles, wiring harnesses, connectors, audio PCBA testing, and assembly services to simplify component matching and integration.
For two-way, three-way, and other coaxial speaker configurations, we evaluate driver placement, crossover frequencies, and mounting structures based on the characteristics of the tweeters and mid/bass drivers. This helps balance vocal clarity, high-frequency detail, and mid/bass performance within limited space.
Based on the installation location and product requirements, we evaluate diaphragm, surround, magnet, and sealing materials to balance acoustic performance, weight, cost, and environmental resistance. Manufacturing follows approved samples and technical specifications, with reliability validation tailored to the application to help achieve the intended sound performance in each device.
