SUB P-10 DSS
ELEGANT AND SIMPLE DESIGN
The cabinet is designed to fit perfectly to the size of the woofer, but without forgoing the inner volume that is needed to produce a powerful bass performance.
All DALI subwoofers are compatible with almost any amplifier, receiver, or processor due to the choice of LFE or LINE inputs.
All amplifiers in DALI subwoofers have the stamina to keep a high-yield performance and the headroom to draw out that little extra when needed.
RIGID CONE STRUCTURE
The rigid cone structure based on either aluminum or cone fiber eliminates the need for a dust cap and helps ensure a piston-like behavior of the woofer.
The DALI SUB P-10 DSS is designed with the goal to set standards for subwoofer performance and experience in your listening room or dedicated home theater.
Unlike many subwoofers in the market, the DALI SUB P-10 DSS has been engineered to perform equally well with both music and movies. It is important to us that a subwoofer is capable of rendering a performance true to the input signal. Therefore a DALI subwoofer is everything but a ‘boombox’.
3 x 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. DALI SUB P-10 DSS features a solid, down-firing woofer, able to move lots of air.
The P-10 DSS remote-controlled subwoofer, with individual settings and memory for stereo and theater, will be the competent upgrade to high-end stereo and home theater systems.
Combination of use
DALI recommends applying the subwoofer with e.g. EPICON, RUBICON, and FAZON F5 systems. APPLICATION But also customers with speakers from other brands will surely find what they need in this subwoofer. The design, technology, and construction of this subwoofer make it a perfect upgrade of any mid to high-end loudspeaker system.
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.
The 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 P-10 DSS 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 P-10 DSS allows you to choose between the 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 favorite listening position. Mute and Power On/Off can also be controlled from a distance.
DALI SUB P-10 DSS is equipped with an active 10” down-firing woofer. The cone is a sandwich construction with carbon fiber at the front paired with paper pulp at the back. The geometry and the material were applied to 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 precise bass reproduction, rendering all the dynamics of the signal.
The 4-layer voice coil is mounted on an aluminum former. In order to reduce potential micro-resonance, the inside of the former has been lined with 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 behavior, even at a 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 copper for optimum signal feed.
The chassis is made from aluminum to prevent any magnetic loss. And lots of research has gone into optimizing the entire construction for the lowest possible mechanical and magnetic loss, and to ensure free airflow.
The two side-mounted woofers share much of the technology from the active driver. Cone geometry is identical to the down-firing woofer, and the cone material is also carbon fiber. The ‘upper’ part of the chassis is the same – 10 legs and identical suspension. However, there is only one spider, and of course no voice coil or magnet system behind it.
None of this is due to the visual appearance, however. The whole purpose of the passive radiator is to follow the movements of the active woofer. Though it looks simpler than the active woofer the passive radiator has been through hundreds of hours of careful designing to achieve the exact same tonal balance as in the active version.
An example: Embedded in the cone of the passive radiator is just the right amount of zinc alloy to achieve the desired weight. Only with the correct weight and distribution of weight, you will get the excursion characteristics you are looking for. Zinc alloy was chosen due to its density and nonmagnetic properties.
The SUB P-10 DSS cabinet is designed and constructed from all our knowledge and experience in acoustics, the solid MDF cabinet abides the tough DALI specifications.
DALI SUB P-10 DSS 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 aluminum base and spacers made from solid aluminum, 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 subwoofer’s ability to go both loud and deep. It features 10 layers of PE lacquer. And in between, each layer is hand polished to ensure a deep, high gloss, and elegant surface.
