JBL 2353 pavillon Bi-Radial® à ouverture optimisée Aperture
[2353] Avis/Critiques Les pavillons "optimized Aperture" (dispersion optimisée) sont conçus pour fourir une pression acoustique élevée tout en maintenant une très faible distorsion dans la bande de fréquence 630Hz - 18kHz ainsi qu'une dispersion uniforme horizontale et verticale. Cette uniformité de la dispersion améliore la prédictabilité des performances et simplifie la conception des grappes d'enceintes (clusters)

1- Measured on axis in the far field with 1 watt (2.83 V RMS, 8 ohms) applied to a 2447H driver and referenced to 1 meter distance using the inverse square law. Listed sound pressure represents an average from 630 Hz to 18 kHz.
2- Using 2447H driver.
JBL continually engages in research related to product improvement. New materials, production methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.
