Multimedia Speakers 2.1

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.

A dual-range speaker with two drivers produces high frequencies from the tweeter and low and mid-range frequencies from the woofer. This maximises output with a more balanced sound than that from the commonly used one-way structure, where a single driver has to produce all the frequencies. So you can enjoy better acoustics with clear vocals and high tones along with solid bass, and all for a very competitive price with this latest Philips range of speakers.

With its box-within-a-box design, this band pass subwoofer has two volume chambers to create more air capacity and deliver an altogether better bass sound with better balance and less distortion. The audio energy from the central driver is concentrated more effectively in the desired frequency output range, producing an overall sound image that is more focused and more accurately reproduced.
