Vonyx WP20 8-Inch Hi-Fi Woofer
The VONYX WP20 woofer brings a polypropylene cone and stiff bass response to car radio and hi-fi applications. Its heat-resistant voice coil, double rolled foam edge and 8-ohm impedance make it a practical choice when you need a dedicated woofer for a compatible speaker system.
Polypropylene Cone, Focused Bass
The flat, semi-transparent polypropylene cone is shaped for the WP series’ woofer design. Meanwhile, the original description highlights its very low resonance frequency and stiff bass response. Together, these details suit listeners and builders looking for defined low-frequency reproduction in a car radio or hi-fi setup.
Built for Regular Use
A heat-resistant voice coil adds confidence during normal operation, while the double rolled foam edge forms part of the woofer’s construction. These features keep the design focused on dependable, straightforward speaker performance without adding unnecessary complexity to the setup.
Easy-to-Identify System Fit
With an 8-inch woofer diameter, 8 Ω impedance and 87 dB sensitivity, the WP20 gives system builders clear figures to check against their enclosure and amplifier requirements. The ferrite magnet and 29 oz magnet weight are also specified, making the woofer easier to assess before installation.
