HIFI 4-Inch Coaxial Speaker Driver 8 Ω 1 Piece with 19 mm Silk-Dome Tweeter for Compact Loudspeaker
Model No: WHFSP-4IN2WCOX
This compact coaxial speaker driver features a natural-sounding 19 mm silk soft-dome tweeter mounted concentrically within a long-throw 4-inch woofer. The shared-axis arrangement is designed to deliver smooth on-axis and off-axis frequency response while helping reduce phase and diffraction issues associated with physically separated drivers in conventional two-way speaker layouts.
The woofer features a curved-profile cone and rubber surround, while the silk-dome tweeter extends high-frequency reproduction up to a specified 20 kHz. An open cast-aluminum basket supports airflow behind the cone and helps reduce power compression.
Separate woofer and tweeter terminals provide flexibility for integration with a suitable crossover network. With a 120 mm overall diameter, this driver is suitable for compact DIY loudspeakers, portable speaker projects, and custom automotive audio installations.
Key Features
- Compact coaxial construction: Integrates a woofer and tweeter within a single mounting footprint.
- 19 mm silk-dome tweeter: Designed for natural high-frequency reproduction.
- 4-inch woofer with rubber surround: Combines a curved-profile cone with a flexible suspension.
- Open cast-aluminum basket: Provides rigid support and ventilation.
- Independent inputs: Separate woofer and tweeter connections support custom crossover designs.

Use an appropriately designed crossover to blend the drivers and protect the tweeter. Frequency ranges and power ratings apply to the individual drivers; the power ratings should not be added together as a system rating. Final system performance depends on the enclosure and crossover design.
