Highlights

 

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 stabilizes the tuning frequency. 

Philips technical and consumer tests confirm this 

buffer provides less colored, purer quality bass.

A single speaker driver normally incurs a specific 

frequency division vibration near the edge of the 

diaphragm, often resulting in some sound distortion. 

This way to overcome this problem 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.

A chamber behind the speaker driver that channels 

air to acoustically tuned vents built into the speaker 

give the bass notes a more punchy, realistic sound.

Now you can enjoy your favorite 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 

3.5mm 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.
