Key features of PHANTOM S-280

One of DALI 's goals for the PHANTOM S and M models was to create high-end in-wall speakers with a slim profile that allowed for maximum flexibility when installed. DALI achieved this by keeping the cabinet depths at only 100-103 mm, which fits into almost any standard wall.

Advanced Soft Magnetic Compound (SMC), which eliminates variation of flux strength in the magnet gap. It reduces distortion to a minimum compared to conventional drivers.

All speakers by DALI are designed around the principle of wide dispersion. This entails an off-axis optimisation of the audio reproduction. The technology is perfect for use in install speakers, since they are always mounted flush against either a wall or ceiling.

PHANTOM S-280 Product Details


The two primary 8” woofers were designed and developed specially for the PHANTOM S-280 and optimized for both bass and midrange performance. The SMC magnet system developed for the EPICON range was chosen as the core for this woofer for its unique ability of dramatically lowering the level of distortion.

Offering 70% more surface area, the 8” woofers 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 detailed information, rich midrange sound and a full frequency response as of a traditional floorstanding speaker.

To ensure the best possible bass performance in the PHANTOM S-280, DALI integrated two 10" passive bass reflex woofers - based on the passive radiator used in DALI 's highend subwoofer 'DALI SUB P-10 DSS'.

By also using the same aluminium chassis, soft surround and very well behaving carbon fibre cones, the passive radiators let the PHANTOM S-280 reach deep down into the true lower frequencies to deliver a believable large boxed speaker sound. But in a very slim cabinet.



The rotatable hybrid tweeter module in the PHANTOM S-280 is the perfect high frequency solution. DALI has a long and well-proven tradition for the use of hybrid tweeter modules, which combines a soft dome tweeter with a ribbon tweeter. This ensures an amazing rendering of the high frequencies, and dispersion of high frequency sounds 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 - one of DALI 's sound design trademarks. Even the detailing of the faceplate for the tweeter module is designed for optimal 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 being 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 2 kHz upwards.



The 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 103 mm (4 inches), getting the perfect inner volume for the woofers had to be found both in the height and width of the speaker, but also internally.

The front of the PHANTOM S-280 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 PHANTOM 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.
