Full-Range Sound in a Compact Speaker

The WZ40PTi 4” coaxial speaker pair is designed to deliver balanced, full-range sound in a compact footprint. With a combined 350W peak power and 80W RMS handling, these speakers provide strong midrange presence and crisp high-frequency detail. Their efficient design makes them suitable for both factory upgrades and performance-oriented audio systems.

Advanced Two-Way Coaxial Design

Each speaker features a durable glass-fiber woofer cone paired with a 44mm PEI dome tweeter. The integrated crossover at 5kHz ensures smooth transitions between frequencies, creating clear vocals, detailed instruments, and bright highs. The Ndfeb tweeter magnet and ferrite woofer magnet work together to maintain accurate response across the 100Hz–20kHz range.

Built for Easy Installation & Long-Term Use

Designed for universal fitment, these speakers offer a shallow 1.66” mounting depth and a 3.74” cutout requirement, making them ideal for dashboards, doors, or custom builds. Their rugged materials and efficient motor structure ensure long-lasting performance even under demanding listening conditions.
