DALI Sub P-10 DSS 10" Active Dual 10" Subwoofer 300W Black

LONG THROW HIGH-POWER DRIVER

With a 4-layer 63.5mm voice coil, 2-piece ferrite magnet with vented pole piece and even dual spiders, the down-firing driver is designed through and through for long excursions, high power handling and size-defying bass volume. Two highly engineered front / back passive radiators complete the acoustic design and further extend low frequency reach.

ELEGANT AND SIMPLE DESIGN

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.

HIGH-YIELD AMPLIFIER

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.

FLEXIBLE CONNECTIVITY

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

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. This is everything but a ‘boombox’.

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

The P-10 DSS remote controlled subwoofer, with individual settings and memory for stereo and theater, is a competent upgrade to any high-end stereo or home theater system.

Combination of use
DALI recommends applying the subwoofer with e.g. EPICON, RUBICON OR FAZON F5 systems, but customers with speakers from any brand will all 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 system.

The cabinet
The SUB P-10 DSS cabinet is designed and constructed all of DALI's knowledge and experience in acoustics.

It features a sealed, 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 reactive movement of the woofer itself.

Applying a sleek aluminium base and spacers made from solid aluminium, the entire cabinet is effectively decoupled from the floor, so much so that it almost appear to float above it. The distance of 45 mm eliminates any potential turbulence from the space between the cabinet and the floor itself, at the same time maintaining proximity to the floor. This 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, 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 total fidelity. 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 P-10 DSS 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 P-10 DSS 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 P-10 DSS 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.

The two side-mounted radiators share much of the technology of the active driver. Cone geometry is identical to the down-firing woofer, and the cone material is also carbon fibre. 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 just for show, however. The whole purpose of the passive radiator is to follow the movements of the active woofer, acting like bass ports to extend bass response but with more sophistication and less distortion, phase-related or otherwise. Though looking simpler than the active woofer the passive radiators have been through hundreds of hours of careful designing to achieve the exact same tonal balance as in the active version.

For 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 will you get the excursion and inertial characteristics to complement and extend the active driver's response. Zinc alloy was chosen due to its density and nonmagnetic properties.
