DALI Sub M-10 D 10" Down-Firing Active Subwoofer 300W Black

Ships in 4 to 7 Days

Given the Cinema and HiFi mode switches, the SUB M-10 D will bring loads of punch into any movie experience and forge on with finesse in the most demanding two-channel music environment as well. With a down-firing woofer, the SUB M-10 D easily reflects the bass out in the room, enabling perfect room integration. All told, this subwoofer is engineered to excel in any system on any program.

  • 10” aluminium long stroke woofer with heavy build for high power handling, bass volume and extension
  • 300W RMS / 500W peak class D amplifier
  • Sealed design, downfiring with solid aluminium base
  • High gloss white or black front baffle


With a 4-layer 63.5mm voice coil, 2-piece ferrite magnet with vented pole piece and even dual spiders, the driver is designed through and through for long excursions, high power handling and size-defying bass volume and extension.


The cabinet is designed to fit perfectly to the size of the woofer, without forgoing the inner volume that is needed to produce a powerful bass performance. An elegant aluminium base gives an illusion of levitation and also serves to position the bass port at an optimal height above ground for
eliminating chuffing while maximising ground coupling.


The 300W (500W peak) subwoofer amplifier has the stamina to keep a high-yield performance and the headroom to draw out that little extra when needed. Remote-adjustable phase, crossover, volume and Cinema / HiFi modes make this sub a snap to integrate and tweak in any system.


With the choice of LFE, mono and stereo LINE inputs, DALI subwoofers are compatible with almost any amplifier, receiver or processor.

A 10 inch long stroke design woofer featuring rigid carbon fiber cones, dual spider, low loss suspension, and massive magnet system are fitted into an elegantly styled, compact enclosure and combined with a powerful digital amplifier with a dynamic output of 500W RMS.

Designed and constructed with all of DALI's knowledge and experience in acoustics, the solid, closed MDF cabinet housing all this satisfies and exceeds the tough DALI specifications. The strong woofer, amp and closed box together bring size-defying bass volume and extension into your room in a tiny package.

DALI recommends applying the subwoofer with e.g. the EPICON, RUBICON or the FAZON F5. But also customers with speakers from other brands will surely find what they need in this subwoofer as well. The design, technology, and construction of this subwoofer make it a perfect upgrade to any mid to high end loudspeaker system.

The remote controlled subwoofer, with individual settings and memory for stereo and theater, will make itself at-home in high-end stereo and home theater systems alike.

To ensure a stable working environment for this woofer the base of the cabinet is made from 25 mm plywood. This guarantees a powerful grip on the driver, eliminating any loss related to reactive movement of the woofer.

Applying a sleek aluminium base and spacers made from solid aluminium, the entire cabinet is effectively decoupled from the floor. Almost appearing to hover above the floor, the distance of 45 mm eliminates any potential turbulence from the space between the cabinet and the floor itself. At the same time the proximity to the floor ensures that the benefit of having a down-firing woofer is maintained: a higher efficiency and a seamless acoustic coupling to the room.

Measuring only 370 x 340 x 340 mm (HxWxD) the cabinet is extremely compact despite this subwoofers ability to go both loud and deep. It features 10 layers of PE lacquer, every layer hand polished to ensure a deep, high gloss and elegant surface.

The powerful, integrated 300 Watt RMS Class D amplifier is highly linear, and will follow and render the input signal with an absolute minimum of bias. Designed not only for continuous power, but also for peak power, this subwoofer is able to deliver 500 Watts Peak Power. This is very important to movie and music signals alike.

Switchmode power supply is part of the reason for very low power consumption and an impressive efficiency within the amplifier. Both this and the high-efficiency amplifier section generate an absolute minimum of heat loss, thus obviating the need for external heat sinks.

The integrated limiter compares the input signal amplitude to the potential output signal level. If this circuit detects a potential problem the limiter will cut the signal in a soft manner and without affecting peak power.

Fitted with controls for gain, cut-off frequency, and phase, the DALI SUB M-10 D will adapt to any front speaker and room acoustics. A remote control for all settings allows you to dial the subwoofer in to perfection while you're seated and listening right at the sweet spot. Mute and Power On/Off can also be controlled from a distance.And with a choice of LFE and LINE inputs it can be connected to almost any amplifier, receiver or processor.

DALI SUB M-10 D allows you to choose between movie and music modes, also via the remote control. For a realistic and powerful rendering of e.g. explosions in a movie, the sound mode may be set to CINEMA, amplifying the lowest frequencies to ensure a realistic experience. For a neutral and very linear performance, the sound mode may be set to HIFI. This will ensure a precise rendering of all the details of the music, while optimizing the integration with your front speakers.

The DALI SUB M-10 D is equipped with an active 10” down-firing woofer. The cone is a sandwich construction with carbon fibre at the front paired with paper pulp at the back. The geometry and material applied eliminate the need for a dust cap. The result is a rigid cone with superior breakup characteristics while at the same time being very lightweight and agile. Indeed these are prerequisites for a precise bass reproduction, rendering all the dynamics of the signal.

The 4-layer voice coil is mounted on an aluminium former. In order to reduce potential micro-resonance, the inside of the former has been lined with a thin paper pulp. The voice coil diameter is a solid 63.5 mm to ensure maximum power handling. A large 2-piece ferrite magnet with a vented pole piece ensures that the voice coil is kept in a tight grip, even when the party gets going.

For optimum control of the cone excursion, the woofer features dual spiders 12 mm apart. In this way the voice coil maintains a 100% piston-like behaviour, even at very high sound pressure level.

Altogether DALI’s low-loss approach is implemented to the maximum. This goes for the surround as well. Made from wide, natural rubber, this part of the suspension also guarantees linearity across the entire 25 mm cone excursion. Even the oversized litz wires are made from solid silver-plated 99.999% oxygen free copper for optimum signal feed.

The woofer chassis is made from aluminium to prevent any magnetic loss. And lots of research has gone into optimizing the entire construction for lowest possible mechanical and magnetic loss, and to ensure a free airflow.
