The D.A.S. 10B is a high efficiency 10” diameter cone loudspeaker with 4”
diameter voice coil. It features centre pole piece convection cooling to provide
high power handling and low power compression.
Exclusive curing techniques
are utilized to create an indestructible bond between the copper voice coil and
its fibre-glass based support. The computer designed injected aluminium basket
supplies rigidity and mechanical grounding.
Applications :
Mid range. Suitable for high-power systems and mid-high boxes.
Features :
» Mid frequency 10” cone loudspeaker
» 800 W program power handling
»
4” voice coil
» Ceramic magnetic structure
