Cabinet design 

 

  

The cabinet shape is not only an aesthetically neat 

shape,  but  also  offer  some  advantages  in  terms  of 
acoustics,  since  nonparallel  walls  reduce  internal 

resonances 

of 

the 

cabinet. 

 

The  cabinet  is  made  from  25mm  MDF  board,  
offering good sonic qualities. 

 

The  cabinet  is  further  strengthened  with  internal 

bars,  which  in  total  ensures  a  very  stable 

construction. 

    

 

Tweeter driver 

 

  

We have selected a ribbon tweeter which provides 
superior transient response and a very flat frequen-
cy response. The ribbon cone is super light and only 

18 microns thick. It is a sandwich construction 

made from rosin-aluminium-rosin that has been 

hardened at 320 degrees Celsius.

 

 

The magnet system is a dual row high efficiency 

neodymium magnets in a moulded chassis of ce-

ramic carbon steel. 
 

Fishbone shaped contactors in aluminium, results 

in a low connection resistance and good heat dis-

tribution.

 

 
The driver has high power durability and handles 

frequencies up to 40000 Hz which makes it DVD-
Audio and SACD-ready. 

   

The  tweeter  in  can  be  rotated,  so  the 
speaker can be standing up or lying down

 

 

Woofer/midrange 
driver 

 

  

After evaluating a large number of drivers from 

different manufacturers we selected one from Seas, 

a company that has a solid reputation in the area of 
high quality speaker drivers. You find Seas drivers 

in many well-known High End speakers. 

 

For woofer/midrange we decided on a 6,5" magne-
sium driver from the Seas Excel series that have 

extreme performance. We claim that finding a 

better 6,5" driver on the market is a very difficult 

task. 

 
The surface treated magnesium cone is extremely 
light but still extremely stiff and effectively reduces 

resonances. 

The rubber surrounding makes sure that no edge 
resonances are present.

 

 

The moulded metal basket is a "high flow" type that 

is acoustically transparent with high precision as 

the basket is shaped exactly due to the moulding 
process. This makes sure that the basket is very 

stable and efficiently reduces resonances. The bas-

ket is absolutely non-magnetic, which contributes 

to a higher efficiency of the driver.

 

 
A strong magnet combined with the light cone 

ensures a high efficiency and a good transient re-

sponse. 

 

Heavy copper rings mounted above and below the 

T-shaped pole piece reduce non linear- and modu-

lation-distortion and increases the overload mar-
gin.
