Shure KSM8/N Dualdyne Vocal Microphone Patented cartridge design features two ultra-thin diaphragms (one active and one passive) and a groundbreaking inverted airflow system Exceptional control of proximity effect greatly increases working distance without on-axis coloration. Frequency response: 40 to 16,000 Hz Neutral mid- and high-frequency reproduction due to controlled proximity effect results in the most natural-sounding dynamic microphone available Neodymium magnet resides in a micro-injection mold of aerospace SoftMag material, maximizing the magnetic field for the highest output level Re-imagined Shure Pumping Pneumatic Shock Mount features tuned cavities, specific resistances, and precisely machined components fully integrated into the cartridges acoustic properties, delivering exceptional rejection of handling noise without any loss of low-frequency response Patent-pending Diaphragm Stabilization System technology protects and stabilizes the active diaphragm from unwanted movement from plosives or impact Dent-resistant, hardened carbon-steel grille design lined with hydrophobic woven fabric provides exceptional water, plosive and wind protection
