High-performance version of the SD20, built around a 20 mm silk dome, the WSD20 DND 04F tweeter is the result of our expertise and our passionate pursuit of technological excellence. It has benefited from extensive development work aimed at achieving high efficiency through the addition of a large waveguide combined with a phase equalizer and a powerful neodymium motor. Combining high audio performances, reliability, and cost control, the WSD20 DND 04F can be paired with 4 to 6.5 inch mid-bass drivers to form an outstanding high-frequency section.
