The Fin, has remarkable, natural, clear sound and was designed especially for live sound, recording and broadcast applications. The exceptional performance is achieved by the use of a special magnet structure with a large 1 1/18″ aluminum low mass voice coil assembly similar to the Heil PR 20. The frequency response is 60 Hz – 18kHz with that traditional Heil Sound mid-range ‘bouquet’ at 4kHz, which presents incredible brilliance and presence. The Fin® exhibits a tight linear cardioid pattern. The chrome finish is a special ‘show-chrome’ where the steel body is copper plated and then double chrome plated producing a deep chrome finish. A blue molded internal foam windscreen inside the grill covers the large diameter Heil dynamic microphone element mounted in a specially tooled shock mount.
