- Linear phase filteis (Bessel function type)
realize natural and equal sound levels in and
around the passband frequency.

- The sound balance of front and rear can be
adjusted without affecting a sub«woofer
sound.

0 40H: low boost control allows dynamic bass
reproduction

'Linear phase filters (Bessel function type) :
Most of the channel dividers currently available
employ flat response filters (Butterworth type). The
group delay characteristic of this type of filters is
much worse than that of the linear phase filters.
and this causes transient distortion in the audio

signals at each filter's crossover lrequency, To _

reduce that distortion and to mm mm sound. Crossover Paint Response Curve
linear phase filters (Bessel tunction type) are used

lor the XEGSOO.
