neodim 1170hz speakers car haut-parleurs enceintes
Wide roll surround together with a double chamber magnet system results in a low fundamental frequency.
Very low magnetic stray fields make this unit suitable for A/V systems. The voice coil is immersed in magnetic fluid, allowing high power handling capacity and simplified crossover design.The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees, mounted in a 0.6m by 0.8m baffle. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m. The impedance is measured without baffle using a 2V sine signal.
