Haut-parleur SEAS CA26RFX
[CA26RFX-8] Avis/Critiques Classical handcoated paper cone and matching natural rubber surround produce a well behaved roll off characteristic and reduce potential resonance problems. 2” high temperature voice coil with black anodized aluminium coil former gives high power handling and reduced power compression.
Large magnet system gives good sensitivity and transient response. 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 resonance to a minimum.
The frequency responses above show measured free field sound pressure in 0, 30, and 60 degrees angle using a 28L 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.
