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.
