Vonyx WPP20 8-Inch Hi-Fi Woofer
The Vonyx WPP20 woofer delivers accurate low and mid-frequency sound. So it’s a practical choice for repairing an existing speaker or building a custom enclosure. Its polypropylene cone, flexible rubber suspension, and efficient venting work together for smooth movement and steady performance.
Clear Bass From a Polypropylene Cone
The polypropylene cone is light, stiff, and self-damping. As a result, the woofer moves with precision. This gives you fast, accurate bass while keeping unwanted noise in check. That makes it a solid base for bookshelf speakers, floorstanding speakers, and custom hi-fi builds that need clear low and mid tones.
Built for Smooth Movement
A flexible rubber suspension lets the cone travel further, so it reproduces low tones clearly. Meanwhile, the 33 oz ferrite magnet gives the coil the control it needs. And the efficient venting helps release heat during long listening sessions. Together, these parts make for a tough replacement part or DIY build.
Ready for Repairs and DIY Builds
Use this 20 cm woofer to swap out a damaged one in an existing speaker. Or, build it into a custom two-way or three-way enclosure. Its 8-ohm impedance fits most amplifiers and receivers. Plus, the 185 mm mounting diameter and 92 mm mounting depth give you the key numbers for planning your install.
