Euphonia IWS 3 Phantom

  

 
Six rectangular magnets and aluminium conductors control and activate the low-mass, 
ultra-thin diaphragm. The magnets are positioned three in front of the diaphragm and three 
behind to ensure a perfectly symmetrical magnetic field.  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The magnets in front of the diaphragm are powerful, compact neodymium magnets, while 
the rear magnets are larger ferrite types for improved heat dissipation. 
  
To obtain perfect dispersion characteristics and optimum energy transfer in the high 
frequencies, a special acoustical lens guides the energy from the diaphragm into the room.  
 
Numerous simulations and experiments have been conducted to carefully optimise the 
pattern and geometry of the acoustical lens. 
 

Low Frequency Level Adjustment 

Because the in-wall speaker is mounted in a reflecting boundary of a wall or 
ceiling, the low frequency sound pressure level is increased.  
 
The level of low frequencies will vary depending on the distance from the 
loudspeaker to the next reflecting boundary such as a corner where the 
walls meet. 
  
Different wall and ceiling types will absorb more or less of the bass energy, which means 
that the listener must have the option of controlling the level of the low frequencies.  
 
To compensate for these variations, Euphonia Phantom incorporates a front-panel switch 
to adjust the bass level. 
 
The switch has two settings “NORMAL” and “ENHANCED”. The low frequency level 
adjustment in the two settings has been carefully tuned based on a number of simulations 
and experiments in different rooms and loudspeaker setups.
