Philips Fidelio SoundSphere docking speakers
Philips Fidelio SoundSphere docking speakers provide both high fidelity sound and hassle-
free access to all your music from iTunes
1 . They exemplify perfection through uncompromised
excellence in acoustic engineering and exceptional craftsmanship. The stunning sound quality
of the Philips Fidelio SoundSphere docking speaker lies within its unique design, through the
patented positioning of the tweeters and the woofer. The inner quality of selected components
and materials, as well as the care taken in tuning the loudspeakers in extreme acoustic
environments, guarantees a sound that is detailed and dynamic in all circumstances.
Philips Fidelio SoundSphere docking speaker utilizes Airplay to seamlessly play music over a
home Wi-Fi network from iTunes on Mac and PC, iPhone, iPad and iPod touch. With AirPlay,
you can enjoy all your music via the high fidelity speakers of the Philips Fidelio SoundSphere
without plugging in cables or even docking your device.
SoundSphere technology
The focus of Philips Fidelio docking products has also been sound quality, pure and simple.
By combining SoundSphere technology with Apple’s Airplay system the SoundSphere offers
a true audiophile performance to deliver a unique Hi-Fi experience. The performance
of the SoundSphere speakers is the result of a seven year research program by Philips
audio experts, excellent acoustic engineering and exceptional craftsmanship. Its striking
appearance is for a reason:
Each Philips Fidelio SoundSphere speaker features the high-frequency transducer - the
tweeter, positioned outside the speaker box. Suspended above, the tweeter’s acoustic
radiation is not impeded by any physical structures so the ideal listening sweet-spot area is
larger. The positioning of this is linked to the acoustic principle that if a driver is mounted
into a large (and usually flat) front baffle, its directivity increases. Conversely, if the tweeter‘s
faceplate dimensions are minimized, the differences perceived in sound when the listener
moves are smaller. This architecture transforms the tweeter, up to high frequencies, into a
point source that emits spherical sound waves - one of the holy grails of acoustics.
Cradling the tweeter below is the low-frequency transducer, or the woofer, which is
positioned and angled in a patented way. Together with rigorous passive crossover
engineering, this minimizes interference between the transducers and ensures the output
of a particularly natural sound. The wider sound dispersion creates an impression that the
instruments are in the room and over a very large listening area.
One challenge was defining the best position for the tweeter in combination with the
woofer - avoiding early reflections on the tweeter cabinet. The solution was to make the
tweeter cabinet and arm as thin as possible to make it acoustically transparent to the
woofer’s sound waves. The combination of the transducers positioning, crossover design,
and structure allows for very balanced and detailed sound throughout the listening room.
A patent application has been filed to protect this unique combination of technology and
design.
“Fidelio SoundSphere speakers feature unique tweeters. Released from
the traditional speaker boxes, the tweeters are free to deliver sound
in all directions. The outcome is a very natural sound, with deeper and
wider sound stage.”
