DALI Phantom S-280 In-Wall Speaker at Vinyl Sound Toronto Canada

The Phantom S-280 is the flagship in-wall speaker from DALI (Hobro, Denmark), available at Vinyl Sound in Toronto, Canada. It is a no-compromise custom installation loudspeaker designed to deliver the full dynamic range and resolution of a high-performance floorstanding speaker from within a standard wall cavity. Two 8-inch SMC wood fibre woofers, two 10-inch carbon fibre passive radiators sourced directly from the DALI SUB P-10 DSS subwoofer, and a rotatable Hybrid Tweeter module achieve a frequency range of 25 Hz to 48 kHz within a mounting depth of just 103 mm. The Phantom S-280 draws on EPICON-developed SMC magnet technology, DALI's patented Hybrid Tweeter, and a solid MDF cabinet engineered to behave as an acoustically inert enclosure despite its slim profile. At 89 dB sensitivity and a recommended amplifier power of 40 to 400 watts, it suits both dedicated stereo listening rooms and the most ambitious multi-channel home cinema installations.

Rotatable Hybrid Tweeter Module for Wide Dispersion

The Phantom S-280 uses DALI's signature Hybrid Tweeter module, combining a 29 mm soft dome tweeter with a high-performance 17 x 45 mm planar ribbon tweeter, both mounted on a cast aluminium faceplate. The soft dome delivers the dynamic impact and clarity expected of pistonic high-frequency reproduction, while the ribbon element extends the response smoothly upward beyond the audible range with a finesse that soft domes cannot replicate alone. A key advantage specific to the Phantom S-280 is that the entire tweeter module is rotatable, allowing the high-frequency dispersion axis to be oriented correctly whether the speaker is installed in a vertical stereo configuration or rotated for use as a centre channel in a multi-channel home cinema system. DALI's wide dispersion design philosophy ensures that the listening sweet spot extends throughout the room rather than being restricted to a single on-axis position, which is essential for the flush-wall mounting position of an in-wall speaker.

EPICON-Derived SMC Magnet System and 8-inch Woofers

The two 8-inch bass and midrange woofers in the Phantom S-280 were designed specifically for this speaker and use the same SMC (Soft Magnetic Composite) magnet system originally developed for DALI's EPICON flagship series. The pole piece of each woofer's ferrite magnet assembly is manufactured from SMC, a material with uniquely high magnetic permeability and very low electrical conductivity. This combination dramatically reduces magnetic hysteresis and eddy current distortion within the motor, lowering third-order harmonic distortion and improving low-level detail retrieval. The 8-inch cone also provides 70 percent more diaphragm surface area compared to a conventional 6.5-inch woofer, enabling greater air displacement at low frequencies and higher sound pressure levels without increased mechanical stress. The wood fibre cone material and low-loss rubber surround further reduce coloration and ensure a natural, coherent midrange character.

10-inch Carbon Fibre Passive Radiators for Deep Bass in a Slim Cabinet

Achieving extended low-frequency response in a speaker with a mounting depth of just 103 mm presents a fundamental acoustic engineering challenge. DALI resolved it in the Phantom S-280 by incorporating two 10-inch passive radiators taken directly from the DALI SUB P-10 DSS dedicated subwoofer, one of DALI's highest-performance bass products. These passive radiators use the same aluminium chassis, soft surround, and carbon fibre cone as the SUB P-10 DSS unit, and they are tuned to move in sympathy with the primary woofers to extend bass output deep into the lower frequencies. The result is a believable large-enclosure bass performance from a speaker that occupies no usable floor space and integrates invisibly into the wall surface.

Cabinet Design and Installation

The Phantom S-280 enclosure is constructed from solid MDF with a rear chamber that is fully sealed and lined internally, providing the correct acoustic volume for the woofers regardless of the wall cavity conditions behind the installation. The extruded aluminium surround frames the speaker elegantly against the wall surface, while the magnet-mounted front grille provides a clean, minimal visual presence. Grilles are paintable to match any wall finish when an invisible installation is required. The dogleg mounting clamp system simplifies installation, securing the speaker firmly to walls of varying thickness without requiring custom carpentry. At just 103 mm mounting depth, the Phantom S-280 fits into most standard domestic wall cavities without structural modification.

Frequently Asked Questions

What is the DALI Phantom S-280?

The DALI Phantom S-280 is the flagship in-wall speaker from DALI, a Danish loudspeaker manufacturer based in Hobro, Denmark. It is a custom installation speaker featuring two 8-inch SMC wood fibre woofers, two 10-inch carbon fibre passive radiators derived from the DALI SUB P-10 DSS subwoofer, and a rotatable Hybrid Tweeter module combining a 29 mm soft dome and a 17 x 45 mm ribbon tweeter. It achieves a frequency range of 25 Hz to 48,000 Hz from a mounting depth of just 103 mm, and is sold as a single speaker for use in stereo pairs or multi-channel home cinema systems.

How does the DALI Phantom S-280 compare to the Sonance Plunge Series and Klipsch Reference In-Wall speakers?

The DALI Phantom S-280 occupies a distinctly higher performance tier than mainstream custom install speakers such as the Klipsch Reference in-wall range. While Klipsch Reference In-Wall models use a single 8-inch woofer and a horn-loaded tweeter, the Phantom S-280 uses a two-woofer plus dual passive radiator system with EPICON-derived SMC magnets and a planar-hybrid tweeter, delivering a frequency response extending to 25 Hz from within the wall rather than requiring a separate subwoofer. Compared to the Sonance Plunge Series, which also targets the high-end custom install market, the Phantom S-280 differs in using DALI's patented SMC motor technology and a rotatable hybrid tweeter module derived from the company's audiophile speaker heritage, resulting in a different sonic character that reviewers have described as complete, refined, and dynamic.

Can the DALI Phantom S-280 replace a subwoofer in a home cinema system?

The DALI Phantom S-280 extends down to 25 Hz in free-field conditions, which is deep enough to reproduce most musical bass content and low-frequency cinematic effects without a dedicated subwoofer. The two 10-inch carbon fibre passive radiators, sourced directly from the DALI SUB P-10 DSS, are responsible for this unusually extended bass performance in a speaker of 103 mm mounting depth. However, for the most demanding home cinema applications requiring maximum impact at the very lowest frequencies, pairing the Phantom S-280 with a dedicated subwoofer such as the DALI SUB P-10 DSS will provide additional headroom and extension. For music listening and most film soundtracks, the Phantom S-280 can operate as a full-range speaker without supplemental bass support.

What is the SMC magnet system in the Phantom S-280, and why does it matter?

SMC stands for Soft Magnetic Composite, a patented DALI magnet motor material originally developed for the EPICON flagship loudspeaker series and applied to the Phantom S-280's two 8-inch woofers. The pole piece inside each woofer's ferrite magnet assembly is made entirely from SMC, a pressed and coated granular material with very high magnetic permeability and very low electrical conductivity. This combination reduces magnetic hysteresis and eddy currents within the motor, which are the primary causes of non-linear, third-order harmonic distortion in conventional driver designs. The audible result is lower distortion at all listening levels, a more relaxed and natural midrange character, and finer low-level detail retrieval compared to conventional in-wall speaker designs.

Where can I buy the DALI Phantom S-280 in Toronto or Canada?

The DALI Phantom S-280 is available at Vinyl Sound, an authorised DALI dealer in Toronto, Canada. Vinyl Sound carries the full DALI Phantom series and can provide consultation on installation planning, system design, and amplifier matching for custom install projects. Purchasing from an authorised Canadian dealer ensures full manufacturer warranty support and access to knowledgeable local advice for custom installation projects.

Can the Phantom S-280 be used as a centre channel speaker?

Yes, the DALI Phantom S-280 is designed to function as a centre channel in multi-channel home cinema systems. The Hybrid Tweeter module is fully rotatable, allowing the high-frequency dispersion axis to be oriented horizontally when the speaker is installed in landscape orientation as a centre channel. This ensures that the ribbon and dome tweeter elements project sound correctly toward the listening position regardless of the speaker's physical orientation. DALI designed the entire Phantom S series with multi-channel flexibility in mind, and the S-280 pairs directly with the Phantom M-675 dedicated centre channel speaker for installations requiring a smaller form factor at the centre position.

What amplifier or AV receiver works best with the DALI Phantom S-280?

The DALI Phantom S-280 operates at an 8-ohm nominal impedance and is recommended for use with amplifiers rated between 40 and 400 watts. Its 8-ohm load is straightforward for most custom install amplifiers and high-quality AV receivers, making it compatible with a wide range of electronics. For stereo listening, dedicated stereo power amplifiers or integrated amplifiers from brands such as Arcam, NAD, or Rotel in the 80 to 200 watt range are well suited. For home cinema use, multi-channel power amplifiers or AV receivers with stable 8-ohm outputs work effectively. The Phantom S-280's 89 dB sensitivity means it reaches high output levels without requiring extreme amplifier power, but it benefits from clean, well-controlled current delivery to take full advantage of its dynamic range and bass extension.
