A LONG STORY IN SHORT Built on experience from the award-winning and highly acclaimed DALI PHANTOM S series, DALI proudly presents a new slimline series of in-wall speakers – DALI PHANTOM M. TWEETER [Page 8] The DALI PHANTOM M-250 has a 28mm dome tweeter, while the M-375 features a state-of-the-art hybrid tweeter. DALI PHANTOM M-SERIES [Page 3] The DALI PHANTOM M series is extremely versatile, slim and flexible in application: The DALI PHANTOM M-250 and the more advanced DALI PHANTOM M-375.
DALI PHANTOM M-SERIES You will find two models within the DALI PHANTOM M series, both extremely versatile, slim and flexible in application. DALI PHANTOM M-250 DALI PHANTOM M-375 The series consists of the DALI PHANTOM M-250 and the more advanced DALI PHANTOM M-375. Both models have been developed with multi-channel applications in mind, and can be mounted either vertically or horizontally. They are both equally suited for front, center or surround positioning.
SPACIOUS SOUND Music is listened to in either active or passive scenarios. Active listening is when you sit in front of a speaker, focussing on the detail in the track. Passive listening takes place typically whilst socialising, where music is playing in the background to create an enjoyable atmosphere. There is a tendency to have a single-point speaker as the main source of music in many homes, chosen for its convenience and easy fit within the interior.
CABINET The DALI PHANTOM M-250 and the DALI PHANTOM M-375 feature the same size cabinet – 250 x 775 mm, with a depth of only 10 cm. On the rear of the integrated bezel you will see a gasket made of EVA rubber, effectively sealing the speaker to the wall when mounted. The cabinet is slim for an in-wall Hi-Fi speaker. The requirements for the cabinet presented our engineers with significant challenges during the development process. The MDF front baffle is firmly mounted to the ABS cabinet.
WOOFER Like all DALI drivers that arededicated to reproducing the low frequency and delicate midrange area, the M-series woofers feature a wood fibre cone. The DALI PHANTOM M-250 speaker is equipped with two identical active 5¼ woofers with two bass ports, whereas the DALI PHANTOM M-375 features one active 7” woofer as well as two passive radiators. The wood fibre cone is a blend of a fine grain paper pulp, reinforced with wood fibres, which result in a rigid, light-weight and well-behaving structure.
WOOFER Passive radiators The dual 7” passive radiators in the M-375 feature a cone geometry optimised for wide dispersion and cabinet volume. Two bass ports on each end of the M-250; these are another way to release pressure from the cabinet, resulting in a compelling spacious and deep sound compared to the size of the cabinet. The rear surface of the passive radiator cones are loaded with small steel weights.
TWEETER Dome tweeter The ultra-lightweight 28mm soft dome tweeter takes care of the high frequency area. Given the size of the voice coil and diaphragm, this dome is perfect for the task. Built for maximum dynamics, great power handling and fantastic integration with midrange frequencies, this tweeter will stay on top of any sound challenge.
CROSSOVER This is what truly defines Hi-Fi systems from average The crossovers help to avoid resonant frequencies speakers. The crossovers of the M-250 and the M-375 and gaps in order to give the optimal playback. All are much alike, but differentiated to match the respectiveloudspeakers from DALI use crossovers and the woofer and tweeter configurations. crossover configurations are different for each type of speaker.
VOICE COIL IN DETAILS DALI PHANTOM M-250 The M-250 woofer features a 4-layer 25mm coil. While a 4-layer voice coil is effective for a high force factor, the higher moving mass will often present a challenge for the midrange response, impairing intelligibility in voice reproduction. Our solution to minimise moving weight is a light copper clad aluminium wire. This solution applies an aluminium core and a thin-walled outer copper tube.
SMC IN DETAILS Low Loss Magnetism The use of SMC (Soft Magnetic Compound) has many advantages, but the overarching result is a significant reduction of distortion from losses in the magnet motor. Iron SMC SMC’s unique ability to deliver a high magnetic conductivity and a very low electrical conductivity gives us all the desired qualities of a really good speaker magnet, without the traditional disadvantages.
Inductance Linearization Making our speakers amplifier-friendly is an important part of the design process. We want to make sure that it is the amplifier and not the speaker that forms the audio signal. To get the best from the amplifier, the speaker has to deliver a stable working environment. By keeping the impedance as flat as possible across the entire frequency range, the amplifier is able to deliver the same amount of power at all frequencies.
PLACEMENT OF SPEAKERS For active listening, placement of the speakers can be just as important as their sound quality. The listener may need to spend time adjusting the positioning of their speakers in order to achieve the perfect setup for an optimised performance. With both stereo and surround setups, the distance between the listener and the sound source needs to be well considered in order to optimise the speakers performance.
