Philips Fidelio Primo docking speaker Designed for audiophile quality, the Fidelio Primo docking speaker for 2012 offers wireless connectivity, AirPlay, and enhanced bass performance with even more clarity than its earlier generations. Enabling consumers to play music from their iPad, iPhone, or iPod with optimum precision, its crossover design lets you hear the detail of every note - natural and complete. With a distinctive, contemporary design, the clean lines and sensuality of the curved wooden back not only look stylish, but create a more effective structure for acoustics, using SoundCurve technology. The bass port has been redesigned to reduce turbulence noise and provide a pure and clean bass. Premium audio technologies including active crossover and PureDigital engineering have been employed for clearer voice presence and vocals, enhanced sound balance, and defined instrument separation. This top-of-the-range speaker epitomizes craftsmanship in terms of acoustics and design - handcrafted from natural materials with its iconic wooden back to give a sleek, premium look that will make a statement even in the most stylish home. 35 SoundCurve technology Elegance meets superb sound quality with the Philips Fidelio Primo docking speaker. It is designed with a curved back which naturally reduces internal resonance, as opposed to conventional parallelepiped box-shaped speaker design which is prone to internal 'standing wave' build-up - a strong energy build-up at a particular frequency.The curvature also increases the stiffness of the speaker cabinet, further reducing internal structural mechanical resonance and coloration, which results in higher precision and natural sound both in midrange and bass reproduction. The listener will recognize the difference in sound quality between the SoundCurve and conventional box-shaped speakers in the midrange (frequency spectrum for voice, guitars and violins). Less resonance brings more precision, therefore improving instrument separation and reducing coloration. Every Fidelio product is a combination of authentic sound, iconic design and simplicity of user experience.The curved back cabinet is a perfect blend of authentic sound and iconic design. "The Fidelio Primo exudes user-friendliness and elegance, crafted to reflect the beauty of objects in the modern home. Superb looks and sensational acoustics cross paths in this docking speaker." Benoît Burette, Sound & Acoustics Innovation Engineer A speaker driver has a front wave, the one you want to hear, and a back wave which is best kept inside the box - it cancels out the front wave and reduces bass level dramatically. When two walls of the box are parallel, the back wave will bounce back and forth between them, creating a standing wave.This resonance at a single frequency is more audible and the sound is said to be 'colored'. Curved walls will make these reflections occur in a more diffused way inside the box, so that the back wave will die away without creating a strong standing wave. Sound remains natural and clear, unaffected by this typical 'shoebox' sound you may get with square boxes designs. 36
