Dali M-10 D Subwoofer

Providing the SUB M-10 D with the feature “cinema mode”, the SUB M-10 D will bring loads of punch into any movie experience. With a down-firing woofer, the SUB M-10 D easily reflects the bass out in the room enabling the perfect room integration. All together, this subwoofer is engineered to perform equally well on both music and movies.

Designed and constructed from all our knowledge and experience in acoustics, the solid MDF cabinet abides the tough DALI specifications.

A 10 inch long stroke design woofers 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.

AMPLIFIER

The powerful, integrated 300 Watt RMS Class D amplifier is highly linear, and will follow and render the required 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 Watt Peak Power. This is very relevant when it comes to both movie and music signals. 

Switchmode power supply is part of the reason for very low power consumption and for an impressive efficiency within the amplifier. In unison the high-efficiency amplifier section and power supply construction generate an absolute minimum of heat loss. For that reason you will find no heat sink on this subwoofer. 

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. 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 a music mode, also via the remote control. For a realistic and powerful rendering of e.g. explosions in a movie, the sound mode should be set to CINEMA, amplifying the lowest frequencies to ensure a realistic experience. For a neutral and very linear performance, the sound mode should 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 subwoofer also features a dedicated remote control that allows you to adjust level, crossover frequency and phase from your favourite listening position. Mute and Power On/Off can also be controlled from a distance.

ACTIVE WOOFER

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 the 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. 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, situated 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 clad 99.999% oxygen free cupper for optimum signal feed. 

The 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.

CABINET

The SUB M-10 D cabinet is designed and constructed from all our knowledge and experience in acoustics, the solid MDF cabinet abides the tough DALI specifications. 

DALI SUB M-10 D features a solid, down-firing woofer, able to move lots of air. 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 the fixation of the woofer itself. 

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 feature 10 layers of PE lacquer. And in between, each layer is hand polished to ensure a deep, high gloss and elegant surface.
