Dali Phantom M-250 In-Wall Speaker (Single)
The PHANTOM M series lets you enjoy a high quality audio performance from compact build-in speakers more than capable of filling a room - discreetly hidden away within your walls.
The PHANTOM M-250 features proven technology, decades of experience and many of the virtues from our reference PHANTOM S series. The PHANTOM M series presents a more compact appearance at a more affordable price point.
The PHANTOM M-250 has been developed with multi-channel in mind and is equally suited for front, center or surround positioning. But as the speaker has to abide to DALI's long-standing sound design principles, it will also work perfectly in a traditional stereo setup - with or without a subwoofer.
The M series is 100% designed and engineered in-house - and manufactured at our own factory.
The PHANTOM M-250 utilizes two 5.25 inch wood fibre woofers, which are designed with a quite "flat" cone geometry to increase the cabinet volume.
All the individual components in the PHANTOM M drivers are assembled in-house. They work in coherence to reproduce clean, detailed sound, with no colouration or unwanted distortion.
Every driver is configured to match the model they are destined for. This is done by optimising the bass drivers for long excursion, and the midrange driver for a large, useful frequency range, so roll-off is handled in the crossover and not in the driver.
This same type of optimisation is achieved for the entire range of woofers used in the M series.
The woofers make use of our patented SMC technology in the magnet system, which leads to a very low result of hysteresis and therefore minimal distortion.
The oversized 28 mm soft dome tweeter in the PHANTOM M-250 is manufactured in-house and built for maximum dynamics, great power handling and fantastic integration with midrange frequencies.
The diaphragm is based on an ultra-lightweight weave fabric. Compared to most soft dome tweeters in the market, the DALI dome material is less than half the weight (0.060 mg per mm2). The relatively large-sized diaphragm lets the tweeter generate a higher sound pressure level with less excursion, keeping the voice coil motion to a minimum.
The soft dome tweeter is additionally optimized for a larger bandwidth in its lower frequency area. This ensures the optimal handover from the mid-woofers to the tweeter, creating a well balanced, unforced and very coherent upper midrange.
Both the PHANTOM M-250 and PHANTOM M-350 feature the exact same size cabinet - including a shallow mounting depth of only 100 mm. This is extremely compact for a serious in-wall speaker. So in order to achieve maximum inner volume for low frequency reproduction, we decided on a cabinet made from glass-reinforced ABS material with overall superior structural strength. The twin bass ports release the pressure of the compact cabinet, resulting in a compelling spacious sound.
As both PHANTOM M models share the same cabinet size, you can wait until a later stage of the installation to decide between the two models.
The front baffle and the rim of the PHANTOM M-250 are lacquered matte black, and you will find no shiny details on the front. This allows for a seamless integration with any home cinema, as you don't want light from the projector reflecting back at you.
The slim bezels of the magnetic and fully paintable front grille allows for a non-intrusive application.
