Haut-parleur SEAS CA22RNY
[CA22RNY-8] Avis/Critiques Classical handcoated paper cone and matching natural rubber surround produce a well behaved roll off characteristic and reduce potential resonance problems. Long, high temperature voice coil wound on an aluminium voice coil former gives low distortion and high power handling capacity.
Extra large magnet system provides high efficiency and good transient response, and parameters that make this driver perfect for high efficiency 2-way system. Bumped backplate in the magnet system allows maximum utilization of the long voice coil without mechanical limitation.
Extremely stiff and stable injection moulded metal basket keeps the critical components in perfect alignment. Large windows in the basket both above and below the spider reduce sound reflexion, air flow noise and cavity resonances to a minimum.
The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 21L closed box. Input 2.83 Vrms, microphone distance 0.5m, normalized to SPL 1m.The dotted line is a calculated response in infinite baffle based on the parameters given for this specific driver. The impedance is measured in free air without baffle using a 2V sine signal.
