Wib100_vPA-S is a professional 4 inch wideband engineered for compact and powerful systems.
It is built with 38.5mm diameter voice coil to ensure reliability during long period and high input power.
The advanced motor structure uses 2x NdFeB magnets (grade N40H), a cooper ring and optimized pole pieces to keep very low THD.
The membrane is built with specific long fibers pressed paper and Aluminum dust cap.
We suggest to use LRC notch filter (as described here after) to get more linear response in high frequency.
