Product Description

Dali Phantom S-280 offers ultimate performance when it comes to custom install loudspeakers without sacrificing valuable living room space. The two primary 8” woofers are optimised for both bass and mid-range performance. Further enhancing the bass performance, they are paired with two 10” passive woofers for a full frequency response similar to a boxed floorstanding speaker.

Hybrid Tweeter

The rotatable hybrid tweeter module in the Phantom S-280 is the perfect high frequency solution, it combines a soft dome tweeter with a ribbon tweeter. This ensures an amazing rendering and dispersion of the high frequencies that outperforms other tweeter technologies. Both the soft dome and the ribbon tweeter are free of artefacts - e.g. resonances and high Q peaks - within their working range.

The hybrid tweeter module features an extremely smooth and wide horizontal dispersion. The characteristics of the soft dome tweeter are low resonance frequency, high power handling, extreme excursions and exceptional headroom for high sound pressure levels. The magneto-static ribbon tweeter trademark is a true master in horizontal distribution of high frequencies and a superb partner for the soft dome tweeter’s unique ability to reproduce frequencies from 2kHz upwards.

Mid/Bass Woofer

The two primary 8” woofers were designed and developed specially for the S-280. The SMC magnet system was chosen as the core of this woofer due to its unique ability of dramatically lowering the level of distortion. The 8” woofers offer 70% more surface area and are able to move more air and deliver a higher sound pressure at very low frequencies compared to a traditional 6½” woofer. All this whilst still delivering the detailed information, rich midrange sound and a full frequency response of a traditional floor-standing speaker.

To ensure the best possible bass performance, Dali integrated two 10" passive bass reflex woofers based on the passive radiator used in the Dali's SUB P-10 DSS Subwoofer. By also using the same aluminium chassis, soft surround and reliable carbon fibre cones, the passive radiators allow the S-280 to reach deep down into the true lower frequencies for a believable large boxed speaker sound from a very slim cabinet.

Cabinet Design

Phantom S-280 features a slim cabinet that fits into almost any standard wall. Constructing a shallow back cabinet was a challenge in several ways. With a depth of only 103mm, getting the perfect inner volume for the woofers had to be found both in the height and width of the speaker as well as internally. The front integrates elegantly with the wall via the surrounding extruded aluminium frame. The picture frame design helps to ensure a large termination point between speaker and wall without a visually dominating footprint.

The magnet mounted front grille forms the visual presence of the S-280. The discreet, simple, but modern design is non-intrusive and at the same time pleasing to the eye. The cabinet is constructed from a solid MDF that holds the easy-to-use dogleg mounting system and the terminals. The rear MDF chamber is entirely wrapped in a high quality black vinyl to complete the look from the painted front baffle. The entire cabinet is designed with a thickness solid enough to avoid resonance.

SMC Technology

Advanced Soft Magnetic Compound (SMC) is used to eliminate the variation of flux strength in the magnet gap. It reduces distortion to a minimum compared to conventional drivers. SMC has the unique ability to deliver very high magnetic conductivity and very low electrical conductivity dramatically lowering the level of distortion while delivering all the wanted qualities of a good magnet system. By surrounding the SMC pole piece with aluminium rings and a 1.5” four-layer voice coil, Dali achieves optimal control, low distortion and high power handling.

The low loss surround and the cone structure is optimised for midrange performance and likewise the dust cap. The smaller than usual dust cap has been arched outward as part of the woofer depth optimisation. All this combined delivers a high bandwidth reproduction with amazing detailing and the ability to deliver well-controlled bass and midrange reproduction.

Wide Dispersion

Using drivers for wide dispersion, Dali loudspeakers are 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-180, since it is always mounted flush against a wall. Working with the off-axis optimisation ensures that the listener will have a large sweet spot where the soundstage is perfect, but also ensures high quality sound away from the central sweet spot.

By optimising the audio signal for off-axis distribution, both the direct signal and the reflected signal will have the same high quality. This means a consistent high quality of sound, across a much wider listening area. The uniform dispersion over a wide range of listening angles ensure a smooth, uniform energy distribution within the listening room, which is another crucial factor for a coherent and well balanced tonality.
