    SPD™ innovative bass port technology for deep, rounded tones

    SPD™ innovative bass port technology for deep, rounded tones

    Philips Sound Purification Duct (SPD) bass port technology delivers the deep, pure tones of the original bass sound. Using an SPD foam material to process the inner surface of the bass pipe, the special acoustic damping invented by Philips reduces noise turbulence and stabilises the tuning frequency. Philips technical and consumer tests confirm this buffer provides less coloured, purer quality bass.

    Bass Reflex Speakers deliver deep and powerful bass

    Bass Reflex Speakers deliver deep and powerful bass

    A chamber behind the speaker driver channels air to the acoustically tuned vents built into the speaker, giving the bass notes a more punchy, realistic sound.

    Well damped driver reduces vibration and sound distortion

    A single speaker driver normally incurs a specific frequency division vibration near the edge of the diaphragm, often resulting in some sound distortion. The way to overcome this problem is by using Mylar, a uniform monomer and a much lighter material that is more usually used, around the driver cone. Surrounding the cone in a perfectly symmetrical ring, the resulting damping effect suppresses the asynchronous vibration, resulting in a more balanced and natural sound.

    Attractive high gloss finish

    High-gloss 'Piano black' finish looks simply superb in both classic and modern interiors.

    AUX-in and headphone out on wired control

    Now you can enjoy your favourite music and entertainment even easier and more conveniently via the aux-in and headphone out jack on wired control. Usually, if you want to connect another device other than your PC, you have to unplug the 3.5 mm jack from the computer and that is not always expedient. But with the aux-in and headphone out connections on front you can quickly and easily listen to music straight from almost any device.
