Euphonia IWS 3 Phantom

  

The front baffle is firmly attached to the aluminium enclosure. Together they form a 

structure that cancels vibrations and resonances. 
 
The rear enclosure fits a standard 4-inch deep wall. Its restricted depth also 
contributes to the preservation of audio quality, as the cabinet is too small for 
standing waves to build up.  
 
The rigidness of the aluminium, the cast bracing ribs, the interior vibration 
absorbing layer, the MDF front baffle combine with the aluminium rear enclosure 
and the compact dimensions of the Euphonia Phantom form a unique sonically 
damped solution, perfect for a high performance in-wall speaker. 
 

 

Driving Miss Phantom    

 

 

 
The Euphonia IWS 3 Phantom employs a 6½” bass/midrange and a Hybrid Tweeter 
Module consisting of a 29 mm soft dome tweeter and a 10 x 55 mm ribbon tweeter in a 
sealed enclosure.   
 

6½” – When Size 

and

 Space Matter 

The 6½” bass/midrange unit is custom-made for the Euphonia series. In order to achieve 
our sound design principles of “Time Coherence” and “3D 
Audio,” the cone must be very fast and very lightweight.  
 
To achieve these goals, we developed a type of paper cone that 
contains unusually long wood fibres in a carefully measured 
proportion.  
 
The shape of the cone is optimised to effectively transform the electrical signal at the voice 
coil into corresponding air motion and to provide wide dispersion – another DALI sound 
design principle.  
 
Paper has a low density and is able to move very fast – at frequencies up to 10 kHz, but 
because of its low mass, vibrations in an ordinary paper cone will have an undesirable 
characteristic sound.  
In Euphonia Phantom, these vibrations are eliminated through the use of wood fibres and 
double coating of the cone.  
 

The wood fibres distribute energy in all directions due to their 
random alignment in the cone, thereby eliminating the material’s 
“own sound”. 
 
The cone, spider and surround are mounted in a rigid, ventilated 
die-cast aluminium chassis with no cavity underneath the spider 
and a vent in the pole piece (yoke) to prevent compression behind 
the dust cap. These measures prevent compression and improve 
free airflow.
