WF146WA05/06 are mid/woofers designed for demanding bass and midrange applications. They work equally well for high-end hi-fi, high quality home theater systems, and top multimedia setups, etc. Powered by a large 90 mm magnet structure that ensures good efficiency and optimal T/S parameters. The large 32 mm voice coil ensures high power handling - thermally and mechanically The new optimized woven glass fibre cone ensures large bandwidth and low distortion. Distortion is further reduced by efficient venting and by adding an internal alu shorting ring to stabilize the magnetic field in the air gap.
