ZEH develops and manufactures woofer speaker drivers for OEM and ODM projects. We match the driver size, structure, impedance, power and low-frequency response to your enclosure, amplifier, crossover and adjoining speaker drivers—not to a fixed off-the-shelf specification.
A woofer speaker driver is designed to reproduce the low-frequency section of an audio system, adding depth, body and impact to music, sound effects and other audio content.
It is commonly used in two-way, three-way and multi-driver speaker systems. Depending on the product design, the woofer may operate together with a tweeter, midrange driver or both.
Woofer performance cannot be determined by diameter or power rating alone. Cone material, suspension, voice coil, magnet, excursion capability, enclosure volume, port design, amplifier output and crossover settings all influence the final low-frequency result.
The woofer drivers below represent existing diameter, frame, cone, magnet, impedance and power platforms.
They are starting points for OEM and ODM development rather than fixed retail products. Each platform can be evaluated or modified around your enclosure, amplifier, crossover, adjoining speaker drivers, acoustic target and production requirements.
ZEH can supply the individual woofer driver or coordinate related components such as the enclosure, grille, wire harness, connector, crossover and amplifier board.
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.
Different products place different demands on speaker size, vocal clarity, sound pressure, enclosure volume, power consumption and long-term reliability. Select an application to see how the acoustic priorities change.
For smart terminals and voice-enabled products, the speaker must reproduce speech clearly inside a compact enclosure while working together with the microphone, audio PCBA and product housing.
Low-profile structure, vocal-band tuning, cavity matching and complete audio hardware coordination.
Interactive toys and learning products need clear speech, comfortable loudness and a structure that remains consistent across repeated use and mass production.
Shape customization, controlled sound pressure and voice-frequency optimization for educational content.
Voice prompts and alarms must remain understandable and stable, while the speaker or module also fits the assembly, supply and reliability requirements of the medical device.
Integrated modules, stable acoustic output, controlled materials and documented validation before production.
Doorbells, panels, sensors and connected terminals often require a small speaker that delivers clear prompts or alerts without taking valuable space from the rest of the electronics.
Compact structures, alert-tone tuning, optional environmental protection and connector integration.
Trackers, training products and portable electronics need compact sound components that survive movement, limited battery capacity and repeated everyday handling.
Small-footprint drivers, efficient notification output and optional sealing or integrated module assembly.
A woofer driver cannot be selected only by diameter, impedance or rated power. It must work correctly with the enclosure, amplifier, crossover and adjoining speaker drivers.
ZEH supports OEM and ODM customers from platform selection and sample development through enclosure matching, prototype validation and volume production.
ZEH evaluates the woofer together with the enclosure, amplifier, crossover, tweeter and, where applicable, the midrange driver.
This helps us recommend a platform that fits the actual product and supports the required low-frequency response, sound pressure and system balance.
Project evaluation can include:
Our existing woofer platforms include different diameters, frames, cone structures, suspensions, magnetic circuits, impedances and power levels.
These platforms provide a practical starting point for OEM development while allowing project-based adjustments to the mechanical, electrical and acoustic specifications.
When an existing platform cannot meet the installation or performance requirements, further structural modification or new tooling can be evaluated.
Beyond the woofer driver, ZEH can coordinate enclosures, ports, grilles, acoustic materials, wire harnesses, connectors, crossover components and amplifier boards.
Evaluating these components together helps improve compatibility, simplify customer assembly and reduce the complexity of managing multiple suppliers.
A woofer may perform differently after it is installed inside the final enclosure and connected to the customer’s amplifier and crossover.
ZEH supports sample development and prototype validation before production. Evaluation can cover:
This process helps identify acoustic, electrical and assembly issues before pilot production.
A woofer is a speaker driver developed mainly to reproduce low-frequency sound.
It is commonly used together with a tweeter, midrange driver or high-frequency unit in a two-way, three-way or multi-driver audio system.
A midbass driver focuses more on upper-bass impact and lower-midrange reproduction.
A woofer generally places greater emphasis on lower-frequency output. The exact difference depends on the driver design, enclosure and intended operating range.
A woofer handles the main low-frequency section of a speaker system and may extend into the lower-midrange region.
A subwoofer is more specifically developed for deeper bass and is commonly used with a dedicated enclosure, amplifier channel or low-pass filter.
Yes. A woofer can be combined with a tweeter or high-frequency driver in a two-way system.
The two drivers must be matched according to their usable frequency ranges, sensitivities, impedance and crossover requirements.
Yes. ZEH can evaluate the outside diameter, mounting depth, frame, hole positions, magnet dimensions and installation structure according to your product housing.
Customization feasibility depends on the selected platform, tooling requirements and expected production volume.
Yes. The nominal impedance, rated power, sensitivity, resonant frequency and frequency response can be evaluated according to the amplifier, enclosure and target sound.
The final parameters must be confirmed through sample development and testing.
Yes. Please provide the enclosure dimensions, internal volume, sealed or ported structure, grille, amplifier and target acoustic requirements.
ZEH can evaluate the woofer platform together with the enclosure and complete audio system.
Yes. You can provide a 2D drawing, 3D file, existing speaker sample, enclosure sample or complete audio product.
Our engineers will review the installation space, electronics, crossover, enclosure and acoustic requirements before recommending or modifying a platform.
Yes. ZEH supports engineering samples, enclosure matching, acoustic evaluation and pilot production before mass manufacturing.
The sample can be evaluated individually and inside the customer’s completed enclosure.
MOQ and development time depend on the selected woofer platform, customization level, tooling requirements, testing scope and expected production volume.
Please provide your technical requirements so ZEH can evaluate the development route and prepare a project-specific quotation.
