Room Tuning & EQ Settings
Mechanical
adjustment of the
boundary frequency
By using the supplied bass plugs in the bass reflex ports, you can alter the lower
boundary frequency of subwoofer. This makes it possible to alter the sound
characteristics of the subwoofer. The picture below shows four settings.
One or two open reflex ports will increase the efficiency so that the subwoofer can
handle higher sound pressure than with both ports closed.
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.
