crossover frequency and listen to the subwoofer in

both phase settings. The setting is correct when the

bass response sounds more powerful and natural.

With incorrect phase the bass response the is more

vague and reduced.

Sound level (VOLUME)

The final stage of the set up process is finding the

right volume level to the subwoofer. At the correct

volume setting the subwoofer will form an integ-

ral part of a complete loudspeaker system. If the

volume is too high the reproduction will be "heavy"

and mask lower frequencies. This will also lead to a

situation where the subwoofer can be localized and

creates a separate sound source.

Filtering

Filtering incorporates Amphion proprietary CSC

technology (Cumulative Stage Coupling), where

the steepness of filtering increases gradually when

frequency increases. This ensures that the phase

changes are as linear as possible and group delay

is minimized. At rejection band (>150Hz) the 5th

order filtering is used (30dB/oktave) which leads

to effective filtering of upper frequencies and solid

stereo imaging. Filter can be by-passed by x-over/

direct- switch when connecting subwoofer to the LFE

channel of the home theatre amplifier.
