Bassreflexports
By using the supplied bass plugs in the bass reflex ports, you can alter the lower
boundary frequency of the subwoofer. This makes it possible to tune the bass
characteristics of the subwoofer to your listening environment and personal taste.
The picture below shows four basic settings.
Below icons representing
the two bassports of the
subwoofer looking from
the front.
Tuning - High freq.
With no plugs in the ports the subwoofer will provide a “quick” and “punchy” bass
character. It has an increased output in the higher bass frequencies.
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 middle bass frequencies.
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.
