Jamo D 4 用户手册

All D 4 cabinets are made of heavy MDF board, a solid and resonance dead base for the 

drivers to work in. 
 

However, the most remarkable cabinet feature is probably the 

Double Curved front baffle. 

It is common knowledge that one of the most rigid constructions 

at all is a round shape; a ball, an egg etc.  
Therefore the front baffle of D 4 has been “cut out” from a giant 

ball and thus the name  “Double Curved” front baffle. It consists 

of a shell, moulded from foamed ABS plastic, mounted on an 

MDF board – with resonance damping foam in between. All 

materials are characterized by excellent acoustic properties i.e. 
high internal damping. This prevents vibrations from “travelling” 

from one driver to another.  

 

Also, the planar design gives optimum working conditions, i.e. a 

minimum of diffractions, for the asymmetrical placed tweeter. By choosing the 
asymmetrical design, no distances from cabinet top and sides to the tweeter are identical 

and thus edge reflections do not accumulate. The result is a crystal clear treble 

reproduction – which is essential in order to benefit from the extended treble contents of 

the new multi channel sound formats. 

 
The finish of the D 4 is a light anthracite lacquered front baffle combined with black ash, 

light – or dark apple wood finished cabinet sides.
