Philips Fideliowireless portable speaker

Thanks to the use of soft dome tweeters, high frequencies are very detailed and precise. This is a technology pioneered by Philips in the 1960s and that since then has been used in the vast majority of high-end loudspeaker boxes. The very open spatial presentation also owes a great deal to these tweeters, which are characterised by very low directivity and distortion; compared to systems using only full-range drivers, the sound is wide and natural, from any position in the listening area.

Despite a very compact acoustic volume, the bass is solid and surprisingly deep, making it possible to enjoy all types of music. This is achieved by using a combination of two high-power woofers and one large area passive radiator per channel, all within a very stiff enclosure that does not lose any bass energy. The large moving mass of the passive radiator makes it possible to tune the system to a very low frequency of 80 Hz, while preventing air turbulence that would otherwise appear with a ported design. Feel the rhythm of the music — don't miss a beat.

Our acoustics engineers spent days and nights optimising the crossover filter to make sure that the sound remains as natural as possible, in very different acoustic environments. From small rooms to open space, from soft listening levels to maximum volume, voices are clear and natural, and the sound is neither aggressive nor tiring, even at loud listening levels. So you can listen for hours and keep on wanting to listen to more of your favourite music.
