DALI Phantom M-675 In-Wall Speaker at Vinyl Sound Toronto Canada

The Phantom M-675 is the flagship model of DALI's Phantom M in-wall speaker series, engineered in Hobro, Denmark and available at Vinyl Sound in Toronto, Canada. Unveiled at CEDIA 2022, the M-675 is a grand yet shallow high-performance in-wall speaker featuring eight drive units, all developed and assembled in-house, making it the most capable speaker in the Phantom M range. Two 7-inch wood fibre active woofers with pure SMC magnet systems, four 7-inch passive radiators with custom stiffened paper and wood fibre cones, and DALI's signature Hybrid Tweeter module combining a 28 mm soft dome with a 17 x 45 mm planar ribbon tweeter deliver a frequency range of 25 Hz to 49,000 Hz from a 100 mm mounting depth. At 90 dB sensitivity and a recommended amplifier power of 40 to 300 watts, the M-675 is designed for high-end home cinema installations and custom Hi-Fi stereo setups in larger rooms where extended bass response and genuine dynamic authority are required. Its fully closed self-contained cabinet requires no separate back box, making it ready to mount out of the box.

Eight In-House Drive Units: Dual Active Woofers and Four Passive Radiators

The M-675's bass system is the most substantial in the Phantom M series. Two 7-inch active wood fibre woofers feature upgraded rubber surrounds and new voice coils compared to the smaller M-375, both engineered for improved low-frequency response and higher power handling. Supporting them are four 7-inch passive radiators with custom paper and wood fibre cone membranes specifically developed for greater stiffness, lower colouration, and more uniform pistonic behaviour. Passive radiators respond to the internal cabinet pressure generated by the active woofers, acting as mechanically tuned bass extensions that add output and extension without the port noise or non-linear behaviour of conventional reflex ports. The combination of two active drivers and four passive radiators within a single 100 mm deep cabinet produces the bass authority and dynamic headroom of a much larger conventional enclosure, enabling the M-675 to fill larger rooms convincingly and to handle demanding home cinema low-frequency content at high output levels. All eight driver units are assembled entirely in-house at DALI's production facilities in Denmark.

Pure SMC Magnet System for Near Distortion-Free Sound

Each active woofer in the M-675 uses a 38 mm voice coil wrapped around a pure SMC (Soft Magnetic Composite) pole piece, the same advanced motor configuration as the Phantom M-375. Pure SMC places the distortion-reducing material throughout the entire magnetic working zone of the voice coil, minimising both magnetic hysteresis and eddy currents across the full excursion range of the driver. The practical result is a near distortion-free bass and midrange presentation with crystal-clear separation of musical details even at elevated playback levels. The SMC system also produces a smooth and consistent impedance characteristic, making the M-675 an easy and stable load for a wide range of custom install amplifiers and AV receivers at its 4-ohm nominal impedance.

Hybrid Tweeter Module: Rotatable for Centre Channel Installation

The M-675's high-frequency section uses DALI's trademark Hybrid Tweeter module, pairing a 28 mm in-house soft dome tweeter with a 17 x 45 mm planar ribbon tweeter element. The soft dome handles the lower treble frequencies from the 2,800 Hz crossover point with broad bandwidth and seamless integration into the upper midrange, while the ribbon element is configured to take over at 15,000 Hz, adding the superior horizontal dispersion and ultra-high-frequency extension that define DALI's audiophile speaker sound. The crossover network runs at three frequencies, 1,000 Hz, 2,800 Hz, and 15,000 Hz, allowing each of the M-675's driver sections to operate within its optimal bandwidth for coherent, natural performance across the full frequency range. The complete hybrid tweeter module can be rotated for correct horizontal dispersion orientation when the speaker is installed in landscape position as a centre channel below or above a screen.

Fully Closed Cabinet with Integrated Back Box

A key installation advantage of the M-675 over the larger Phantom S series is its fully closed, self-contained cabinet. The glass-reinforced ABS enclosure is a complete acoustic system with no dependence on wall cavity conditions behind the installation point. This eliminates the need for a separate custom back box and means the M-675 is literally ready to mount out of the box as soon as the wall opening is prepared. Six spring-loaded dogleg clamps secure the speaker firmly against the wall surface without rattle or movement. The front baffle and surround are matte-black lacquered to prevent light reflection in dark projection environments, while the slim-bezel magnetic front grille is fully paintable for invisible integration into any wall colour. An optional on-wall frame is also available separately, allowing the M-675 to be surface-mounted on concrete, masonry, or other walls where in-wall installation is not practical, a capability DALI describes as quite unique in the custom install market.

Frequently Asked Questions

What is the DALI Phantom M-675?

The DALI Phantom M-675 is the flagship model of DALI's Phantom M in-wall speaker series, designed and manufactured in Hobro, Denmark. Unveiled at CEDIA 2022, it is a two-and-a-half-way custom installation speaker featuring eight in-house drive units: two active 7-inch wood fibre woofers with pure SMC magnet systems, four 7-inch passive radiators, and a Hybrid Tweeter module combining a 28 mm soft dome with a 17 x 45 mm planar ribbon tweeter. Its frequency range extends from 25 Hz to 49,000 Hz with 90 dB sensitivity and 110 dB maximum SPL from a 100 mm mounting depth. The M-675 is sold individually and designed for high-end home cinema and custom stereo installations in larger rooms.

How does the DALI Phantom M-675 compare to the Phantom M-375 and Phantom S-180?

The M-675 sits above the M-375 and below the Phantom S-180 in DALI's custom installation range. Compared to the M-375, the M-675 doubles the active woofer count from one to two 7-inch drivers and increases the passive radiator count from two to four, substantially increasing bass output, extension, and dynamic headroom. The M-675 also extends lower to 25 Hz versus 57 Hz for the M-375. Both share the same pure SMC pole piece magnet system and Hybrid Tweeter module. Compared to the Phantom S-180, the M-675 has a slimmer overall profile and requires no separate back box, making it easier to install in tighter spaces or adjacent to large televisions, while the S-180 uses an 8-inch EPICON-derived SMC woofer and a 10-inch carbon fibre passive radiator from the DALI SUB P-10 DSS subwoofer for a different bass character and deeper overall extension.

Can the DALI Phantom M-675 be used as a centre channel speaker?

Yes, the DALI Phantom M-675 is designed to function as a centre channel speaker in high-end multi-channel home cinema installations. Its Hybrid Tweeter module can be rotated for correct horizontal dispersion when the speaker is installed in landscape orientation below or above a screen. The M-675's three-way crossover and wide dispersion engineering maintain consistent tonal balance from the horizontal listening position. Reviewers from Majik House noted that the M-675 was chosen as the centre channel speaker in a high-performance 5.1 home cinema installation paired with Phantom S-280 main speakers, with the resulting soundstage described as seamless, immersive, and free from any sense of speaker location.

Does the DALI Phantom M-675 need a separate back box during installation?

No. The Phantom M-675 uses a fully closed, self-contained glass-reinforced ABS cabinet with an integrated back box. This means the speaker's acoustic performance is completely controlled by its own enclosure and does not depend on the wall cavity behind the installation point. It can be installed directly into any standard wall opening matching the cut-out dimensions without any additional carpentry or back box preparation. This is a significant practical advantage over speakers that require a custom back box to be built into the wall in advance, and it makes the M-675 one of the most straightforward speakers in its performance class to install.

Where can I buy the DALI Phantom M-675 in Toronto or Canada?

The DALI Phantom M-675 is available at Vinyl Sound, an authorised DALI dealer in Toronto, Canada. Vinyl Sound carries the complete DALI Phantom M and S series and can assist with system design, multi-channel layout planning, amplifier matching, and installation consultation for custom home cinema and hi-fi projects. Purchasing from an authorised Canadian dealer ensures full DALI manufacturer warranty coverage and access to experienced local support throughout the project.

What amplifier power does the DALI Phantom M-675 require?

The DALI Phantom M-675 is rated for 40 to 300 watts at a 4-ohm nominal impedance. Its 90 dB sensitivity means it reaches high listening levels from relatively modest power, but a stable current delivery into 4 ohms is important for controlling its dual active woofers accurately at higher listening levels. Multi-channel power amplifiers and AV receivers with 4-ohm rated outputs from brands such as Anthem, Arcam, Rotel, and NAD are well matched. For the most demanding large-room installations, high-current power amplifiers rated from 150 to 300 watts per channel provide the dynamic headroom to exploit the M-675's full output capability from its dual woofer and quad passive radiator bass system.

Can the DALI Phantom M-675 also be mounted on a wall surface rather than in-wall?

Yes. An optional on-wall frame is available for the Phantom M-675, allowing it to be surface-mounted on walls where in-wall installation is not practical, such as concrete or masonry construction. DALI describes this surface-mounting option as quite unique in the custom installation market at this performance level. The on-wall frame holds the M-675 flush against the wall surface, maintaining the speaker's slim profile and discreet appearance while avoiding the need to cut into the wall substrate. The magnetic paintable front grille remains fully functional in either mounting configuration.
