Mechanical adjustment
of the boundary
frequency
This schematic picture (which does not shown actual measured curves) elucidates the different sonic characteristics of the bass
frequencies.
By using the supplied bass plugs in the bass reflex
gates, you can alter the lower boundary frequency
on the XTZ 99.38 MKII.
The level can be adjusted in 6 different levels in the
bass range.
Also the treble level may be adjusted, which allows
you to perfectly alter the sonic to fit the room,
equipment and your own taste.
The speaker is parted in two bass reflex chambers,
one for the midrange / woofer driver and one for
the woofer. The uppermost gate is for the
midrange/woofer while the two lowermost gates
are for the woofer.
The figure below illustrates three basic settings.
Deep bass
With one bass plugs in lower of the two lower gates
you have the deepest possible bass, which may be
suitable for smaller rooms.
This is under the condition that the bass level is set
at mode 2 (+3dB).
"Quick" bass
Without bass reflex plugs in the gates, you have a
"quick" bass which is especially suitable for large
rooms where the lower frequencies often are
amplified by the room.
Neutral bass
With two plugs in two gates you have a flat
frequency response.
This is under the condition that the bass level is set
at mode 1 (0dB).

This setting also depends on the size and
shape of the room, and also on your own taste,
so please has patience when trying out your
