PRODUCT DETAILS
A 3 x 10”-os hosszúlöketű mélysugárzó tervezés jellemzője a merev szénszálas kúp, az alacsony veszteségű felfüggesztés és a masszív mágneses rendszer. Mindez be lett illesztve egy elegáns stílusú, kompakt méretű házba együtt az erőteljes digitális erősítővel, melynek dinamikus teljesítménye 500W (RMS).
A P-10 DSS távvezérlős mélynyomó a memóriában tárolja az egyéni beállításokat a sztereó és a mozi üzemmódhoz. Ez a megfelelő frissítés és fejlesztés a high-end sztereó és házimozi rendszerében.
Ellentétben a piacon található számos mélynyomóval, a DALI SUB P-10 DSS-t úgy tervezték, hogy ugyanolyan jó teljesítményt nyújtson mind zenén, mind pedig filmeken. Fontos számunkra, hogy egy mélynyomó képes legyen hitelesen visszaadni a bemenetére érkező jeleket. Ezért ez a DALI mélysugárzó minden, csak nem egy "boombox".
A kabinet
A tervezés és a kivitelezés terén ez a Sub minden akusztikával kapcsolatos tudásunkat és tapasztalatunkat tartalmazza. A szilárd MDF kabinet minden pontban követi a kemény DALI előírásokat.
A mindössze 370 x 340 x 340 mm-es (Ma x Szé x Mé) kabinet rendkívül kompakt, ennek ellenére ez a mélynyomó hangos és emellett rendkívül mélyre megy. A kabinet felülete 10 rétegű PE lakk fényezést kapott. Mindegyik réteg kézzel polírozott, amely biztosítja a magas fényű és elegáns felületet.
DALI SUB P-10 DSS tartalmaz egy szilárd, lefelé sugárzó mélynyomót, mely igen sok levegőt tud megmozgatni. Annak érdekében, hogy stabil akusztikai környezetet biztosítsunk, a doboz alapja 25 mm-es rétegelt lemezből készült. Ez garantálja a meghajtó erős felfüggesztését, így nincs semmilyen veszteség a mélynyomó rögzítésével kapcsolatosan.
A subwoofer alkalmazása
A DALI a SUB P-10 DSS mélysugárzót az EPICON, HELICON, MENTOR és FAZON F5 rendszerekhez ajánlja.
ALKALMAZÁS – más márkákból összeállított rendszerek tulajdonosai is hamar rájönnek, hogy erre a mélynyomóra van szükségük. A tervezés, a technológia és a subwoofer megépítése teszi ezt a mélysugárzót minden közép-és high-end hangsugárzó rendszer tökéletes kiegészítőjévé.

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 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 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 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 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.
PASSIVE WOOFERS
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 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 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.
CABINET
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 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.
