As a part of XTZ room tuning concept, our subwoofers are often supplied with two ports and foam
plugs. By using the supplied foam plugs in the bass reflex ports, you can alter the lower boundary
frequency of the subwoofer. This makes it possible to alter the sound characteristics of the subwoofer.
The picture below shows four settings:
Tuning - High freq.
With no plugs in the ports the subwoofer will provide a "quick" and "punchy" bass character. It has increased
output higher up in frequency.
Tuning - Mid freq.
If the left port is blocked and the right port is open, this will provide a bass with an increased output in the
mid region.
Tuning - Low freq.
If the right port is blocked and the left port is open, this will provide a deep bass with an increased output in
the lower frequencies.
Closed
With both ports blocked this
closed box will provide a dry
and controlled bass character.
