CABINETS 
 
 
To  ensure the best possible appearance, the 
surface of the aluminium line is treated with the 
highest grade of aluminium processing.  
After being precisely machined and CNC milled, 
all aluminium parts are bead blasted and 
transparently anodized.  
To maximize internal volume, we  profited from 
the stiffness of aluminium to realize a slim walled 
cabinet. Furthermore, the aluminium panels are 
curved to optimize both stiffness and freedom 
from resonance, which is so  crucial  for natural 
sound. This curve means that while the average 
depth of the speaker is 50 mm (2 inches), it 
reaches a maximum point of 84 mm (3.3 inches) 
in the center of the arch.  
The extra available space in the middle of the 
cabinet allows for the use of physically deeper  
pure  
high-end mid-bass drivers.
 
An additional benefit 
of the  speakers´  shape is  the lack of  parallel  
walls, 
which avoids internal standing waves from 
adver-sely affecting performance. 
  
In extensive research we found out that it is vital 
not to use a single enclosed form in creating the 
box, but to break the cabinet into two separate 
elements connected by MDF, with additional dam-
ping strips between the  MDF and the aluminium, 
in  
order to completely eliminate deleterious cabinet 
resonance.
