DALI SUB P-10 DSS WHITEPAPER
INTRODUCTION The new DALI SUB P-10DSS is designed with the goal to set standards for subwoofer performance and experience in your listening room or dedicated home theater . 3 x 10 inch long stroke design woofers featuring rigid carbon fiber cones, dual spider, low loss suspension and massive magnets system are shoe-horned into an elegantly styled , compact enclosure and combined with powerful digital amplifier with dynamic output of 500 W RMS.
ACOUSTIC BACKGROUND DALI SUB P-10 DSS Frequency Response 110.0 dBSPL 100.0 90.0 80.0 70.0 60.0 20 50 100 200 Hz 500 An impressive frequency response for a powerful subwoofer in an extremely compact cabinet. The DALI SUB P-10 DSS is all about high fidelity. Unlike many subwoofers in the market the DALI SUB P-10 DSS has been engineered to perform equally well on both music and movies. It is important to us that a subwoofer is capable of rendering a performance true to the input signal.
CABINET Designed and constructed from all our knowledge and experience in acoustics, the solid MDF cabinet abides the tough DALI specifications. Measuring only 370 x 340 x 340 mm (HxWxD) the cabinet is extremely compact despite this subwoofers ability to go both loud and deep. There are two finishes available for this enclosure – High Gloss Black and High Gloss White. Both of them feature 10 layers of PE lacquer. And in between, each layer is hand polished to ensure a deep, high gloss and elegant surface.

An example of DALI’s meticulous attention to details: Even the screws used for mounting the drivers have been developed especially for this purpose.
DRIVERS In order to achieve our targets for highest sound pressure level combined with lowest possible distortion in this compact cabinet, neither a closed chamber nor a bass reflex cabinet would do. Instead the subwoofer features two passive side-mounted radiators. These can be tuned to reach further down in the frequency area than a bass port would be able to do in this size of cabinet. In this design the tuning frequency is 31.5Hz.
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.
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.
APPLICATION Available in High Gloss Black and High Gloss White, DALI SUB P-10 DSS is the natural companion for many speakers. DALI recommends applying the subwoofer with e.g. EPICON, HELICON, MENTOR and FAZON F5 systems. 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 speaker system. Whether it’s a 2.1-, 5.1- or 7.
