DALI PHANTOM S WHITEPAPER
INTRODUCTION The enjoyment of music is the cornerstone of everything that DALI does. From manufacturing speakers to our engagement in the music scene, our mission is to bring a high quality audio experience to you no matter what the circumstances. We know that finding space for traditional boxed speakers in a living room, in certain cases, is almost impossible. We also understand the need for enjoying music even if the speakers have to be discreetly hidden away.
PRODUCTS The DALI PHANTOM S series consists of three models for maximum flexibility. The compact PHANTOM S-80, the full-size PHANTOM S-180 and the power-house of the family, the PHANTOM S-280. All models are built around a rotatable hybrid tweeter module, enabling both vertical and horizontal mounting. This makes them easy to install for any audio use: stereo, centre channel, surround speakers and even hight positions if placed close to or in the ceiling. PHANTOM S-180 and PHANTOM S-80.
PHANTOM S-80 The most compact model in the range, offering the optimal balance between audio performance and flexibility in placement. With its 8” bass/mid-range woofer working in combination with the rotatable hybrid tweeter module, it delivers a clear and very well defined audio reproduction including a surprising bass performance. The relative compactness of the PHANTOM S-80 makes it perfect for any placement in your audio system. Front, centre, rear or hight positions. DALI PHANTOM S DALI A/S www.
PHANTOM S-180 The S-180 takes all qualities of the S-80 one step further by adding a massive 10” passive radiator to work in combination with the 8” bass/mid-range driver. This combination enables the PHANTOM S-180 to reach even deeper down in the lower frequencies and reproduce the audio signal on par with a traditional floor standing speaker. Despite this, it is still a compact speaker that is perfect as front left or right, or centre speaker in your audio system. DALI PHANTOM S DALI A/S www.
PHANTOM S-280 Taking everything to a new level, the S-280 is true flagship in-wall speaker. Combining an improved rotatable hybrid tweeter module, two 8” bass/mid-range drivers and no less than two 10” passive radiators, this 152 cm powerhouse of an in-wall speaker needs to be heard to be believed. Clean, coherent, detailed, powerful and room filling sound is what this speaker is all about. If you are looking for a no compromise performance in an in-wall speaker, the PHANTOM S-280 delivers, and then some.
The woofer magnet penetrates the back of the cabinet allowing for long-throw 8” woofer. The drivers are mounted in a black painted solid MDF front baffle. DESIGN GOALS Before the first lines were drawn on the PHANTOM S series, we set out a handful of fixed goals we wanted to meet.
CABINET Constructing a shallow back cabinet for the PHANTOM S series was a challenge in more ways than one. With a depth of only 103 mm (4 inches) getting the perfect inner volume for the woofer(s) had to be found both in the height and width of the speaker, but also internally. The visual appearance of the speaker had to be both pleasing in form, small enough to blend in with the room and made for optimum listening.
WOOFER With the aim of generating a high frequency span and obtaining optimum sound pressure from all models, it was decided to design an 8” bass/midrange driver specifically for the PHANTOM S series. Offering 70% more surface area, the 8” woofer is able to move more air and deliver a higher sound pressure at very low frequencies compare to a traditional 6½” woofer. All this whilst still delivering detailed information and rich midrange sound.

While at the same time delivering all the wanted qualities of a good magnet system. Utilising the SMC pole piece surrounded with aluminium rings and the 1.5” four-layer voice coil, optimal control, low distortion and high power handling was achieved.
PASSIVE RADIATOR True low frequency performance in a small cabinet is almost impossible to achieve, and the remedy is usually the integration of a bass port. Using a bass port in a shallow installation cabinet serves up two big challenges, getting the bass port the correct length, and controlling airflow through the front grille. By integrating a passive bass reflex woofer the above challenges were eliminated without losing the ability to generate true bass.
Building on the passive radiator used in our highend subwoofer SUB P—10 DSS, the passive radiator for the PHANTOM S series was created. Using the same aluminium chassis, soft surround and very well behaving carbon fibre cone, the passive radiator lets the PHANTOM S-180 and PHANTOM S-280 reach deep down into the lower frequencies to deliver a believable large boxed speaker sound.
TWEETER DALI has a long and well proven tradition for the use of hybrid tweeter modules. This is the combination of a soft dome tweeter working together with a ribbon tweeter for an amazing rendering of the high frequencies, and dispersion of high frequency sounds that outperforms other tweeter technologies. DOME Enclosed in a separate chamber the planar ribbon diaphragm supports the soft dome way above the audible limit of the human ear.
DALI’s wide dispersion technology fill every corner of the room with high quality audio and let the listener experience the music even if he is not placed in the sweet spot. WIDE DISPERSION By designing our drivers for wide dispersion, we make our loudspeakers easy to integrate into any room, delivering a smooth and well integrated sound for a wider listening position. This technology is perfect for the PHANTOM S series, since they are always mounted flush against a wall.
The magnet mounted, floating front grille forms the visual presence of the PHANTOM S series speaker. The discrete, simple, but modern design is nonintrusive and at the same time pleasing to the eye. APPLICATION The PHANTOM S series delivers true Hi-Fi performance, elegantly integrated into any room. Delivering high quality audio previously only achieved through large boxed speakers, the PHANTOM S sets new standards for in-wall performance.
