Discover the Discovery 10F/4424G00 from Scanspeak, a 4″ (10 cm) midrange driver known for its advanced technologies and top-notch craftsmanship. This midrange driver offers a very wide frequency range from 100 to 22,000 Hz, supported by a powerful neodymium magnet and a patented fiber glass diaphragm. With a compact size and an aluminum chassis, it is ideal for versatile applications. Additional features include a high sensitivity of 90 dB at 2.83 V, an SBR rubber surround, and a protective cap including grille. The resonance-free coating of the diaphragm significantly reduces vibrations.
