- Page 2 Therefore, DALI set out to create in-wall loudspeakers that would be fully the sonic equal of any comparably priced conventional design, but with the added convenience and discretion that only built-in loudspeakers can offer.
- Page 3 A Stable Platform A wall can vary tremendously in stiffness and therefore exert significant influence on audio performance. DALI addresses the problem of a “soft” wall by making the Euphonia Phantom itself quite heavy and rigid, a massive 7 kilos (16 lbs.).
- Page 4 In a typical in-wall speaker with an open back, the material in the cavity wall will exert major influence on the sound. Because it is impossible to predict what, if any, materials will be present in the cavity wall, DALI has eliminated this great unknown by employing an airtight sealed enclosure for the Euphonia Phantom.
- Page 5 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.
- Page 6 White Paper Euphonia IWS 3 Phantom The magnet system is optimised for minimal distortion. In order to achieve low distortion, the magnetic field (flux density) must be absolutely stable and independent of voice coil motion. In a traditional magnet design, maximizing flux in the voice coil gap is a high priority. Such designs typically use a thick pole plate in order to increase the conductivity of the magnetic circuit.
- Page 7 The Hybrid Tweeter Module is in our view the ideal high frequency solution. Both the soft dome and the ribbon tweeter are artifact-free (e.g. resonances and high Q peaks within their working range). They both deliver extremely smooth, wide horizontal dispersion, one of DALI’s sound design trademarks. Frequency response...
- Page 8 Deserves a Ribbon As in the ultra high end DALI MegaLine, a ribbon tweeter is used in DALI Euphonia IWS 3 Phantom. The ribbon tweeter has a broad frequency band and superb dispersion of the highest frequencies.
- Page 9 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.
- Page 10 Subwoofer ”Normal” The ENHANCED setting is recommended if the speaker is either some distance away from sidewalls or if the ceiling absorbs a substantial portion of the low frequency energy. The “ENHANCED” setting will boost the level of the lower frequencies and thereby compensate for a room that absorbs some low frequency energy.
- Page 11 Low frequency adjustment is also beneficial when the Euphonia IWS 3 Phantoms is used in conjunction with a subwoofer. Typically, it is possible to achieve better integration between the subwoofer and the Euphonia Phantoms by experimenting with the low frequency level switch and the various settings of the subwoofer (phase, level, crossover frequency).
- Page 12 The template also helps mark the wall for the cutout of the hole in the wall. When it all comes together The DALI sound design principle of “Wide Dispersion” is a perfect match for an in-wall speaker. The in-wall speaker is fixed to a certain position in the room and the wide linear...
