EPOS CENTRE CHANNEL TECHNOLOGY

Naturally occurring distortion is caused by running two drivers closely in parallel with the same frequency response. The human ear is very sensitive to colouration of the voice.

Epos has significantly reduced this phenomenon by tailoring the low frequency extreme of one of the two drivers, by coupling it via a capacitor. This has, in effect, made it into a three way speaker with a woofer, mid- range and tweeter.

This is particularly important for a centre channel speaker because it mainly handles speech.

It should be noted that the effect of rolling off one of the two drivers at low frequencies will cause the image to appear very slightly offset from the middle of the speaker. It will appear between the tweeter and one woofer.

The topology of the ELS 3C crossover is very similar to the ELS 3, which has a second order low pass filer for the woofer, the same for the mid-range, but with an additional first order high pass filter rolling off at 150 Hz, and a third order high pass filter for the tweeter with a crossover frequency of 3 kHz.

A similar parallel can be drawn between the M8 centre channel and the M5 loudspeaker.

These filters are created using high quality audio grade components, with inductions built to withstand high signal levels without distortion.
