In this case instead of fitting the columns into the wall, as the OW FRAME accessory you can place the columns into the wall surface.

DALI PHANTOM M-250

The slim, narrow design of the PHANTOM M-250 has been developed for multi-channel recessed installations. Delivering spacious, room-filling DALI sound for your home cinema, without dominating the physical space of your living room.

WIDE DISPERSION

All DALI speakers are designed for wide dispersion. This means an optimization of off-axis audio reproduction and is a perfect technology for installing speakers, embedding them inside or on the wall.

THIN HOUSING

One of the objectives of the PHANTOM S and M models is to create high-end built-in speakers with a narrow design that allows maximum installation flexibility. DALI has achieved this, providing them with housing depths of only 100-103mm, which fits into most standard walls.

MAGNETIC GRILL

The magnetic and floating front grill shapes the visual presence of PHANTOM S and M. The Nordic design, simple, discreet and modern, is non-intrusive and, at the same time, pleasing to the eye.

TRADITIONAL SPEAKER TECHNOLOGY

PHANTOM high-end speakers are the natural choice when looking for an audio installation for a hi-fi experience. Not only does the PHANTOM H consist of wood fiber cones and drivers built into a classic MDF baffle, but the placement of the woofer and tweeter are similar to those of our classic speakers.

The PHANTOM M series allows you to enjoy high-quality audio reproduction through compact built-in speakers, more than capable of filling the room with their sound while remaining discreetly hidden in the walls.

The PHANTOM M-250 has proven technology, decades of experience and many of the virtues of the PHANTOM M reference range. The PHANTOM M series has a more compact aesthetic and more affordable prices.

The PHANTOM M-250 has been developed to be part of multichannel systems, whether as front, center or surround. But since this speaker complies with DALI sound principles, it also works perfectly in a traditional stereo setup – with or without a subwoofer.

The M series has been 100% designed and assembled in the DALI factory.

WOOFERS

The DALI PHANTOM M-250 has two 5.25” wood fiber woofers, designed with a very “flat” cone geometry to increase the volume in the housing.

All individual components of the PHANTOM M drivers have been assembled in the DALI factory in Denmark. They work consistently to reproduce a clean, detailed sound, without unwanted coloration or distortion.

Each driver is configured for the model it is intended for. This optimizes the bass drivers for long excrusion and the midrange driver for a wide and useful frequency range. So the roll-off is in the hands of the crossover, not the driver.

This optimization process is carried out for all M Series woofers.

The woofers feature DALI's patented SMC technology in the magnetic system, resulting in very low hysteresis and minimal distortion.

TWEETER

The oversized 28mm tweeter of the PHANTOM M-250 is manufactured in the DALI factory with attention to detail to achieve maximum dynamics, great supported power and fantastic integration with mid-range frequencies.

The diaphragm is constructed with a wave of ultra-light fabric. Compared to most soft dome tweeters on the market, the DALI dome material weighs less than half (0.060 mg per mm2). The relatively large size of the diaphragm allows the tweeter to generate a higher level of sound pressure, leaving voice coil movement to a minimum.

The soft dome tweeter is also optimized for greater bandwidth in its lower frequency area. This guarantees optimal management with the woofers, creating a balanced midrange, without tension and very coherent in its highest part.

CASING

Both the PHANTOM M-250 and PHANTOM M-350 feature the same housing size – including a mounting depth of just 100mm. This size is really compact for a fully built-in speaker. Therefore, to achieve maximum volume inside the housing for low frequency reproduction, DALI decided on a housing made of glass-reinforced ABS, which provides superior structural strength to the entire structure. Twin bass ports take pressure off the compact housing, achieving a satisfying, spacious sound.

As both PHANTOM M models have the same case size, you can wait until a more advanced stage of installation to decide between the two.

The front baffle and edge of the Phantom M-250 are lacquered in matte black, and you won't find any shiny details on the front. This facilitates easy integration with any home cinema, in which as a user you do not want the light from the projector to reflect anywhere except in the image on the screen.

The thin front grill visor, magnetic and completely paintable, allows for a zero-intrusive aesthetic in the room.

SMC

The use of the SMC (Soft Magnetic Compound) of the PHANTOM M-250 has many advantages, but by adding the SMC in an area close to the magnet gap, the overall result is a notable reduction in distortion due to losses in the magnetic motor.

SMC's unique ability to offer high magnetic conductivity and very low electrical conductivity offers the qualities necessary for a great speaker magnet, without the traditional disadvantages.

When using iron magnets in speakers, the magnetization and demagnetization caused by the directions of the different currents do not follow the same pattern. The demagnetization process is slower than the magnetization process. This phenomenon is called hysteresis and is a known problem in most speaker magnetic motor systems.

The problem with hysteresis is that it induces unintentional resistance in the voice coil, leading to unwanted distortion. Hysteresis happens because iron not only conducts magnetism, but is also a great electrical conductor.

For its part, SMC is a very highly magnetic conductor, but it has very low electrical conductivity (around 1/10,000 parts compared to iron). The result of using SMC is that there is almost no hysteresis, and therefore no distortion.
