using the POrt tuBe inserts (all MOdels exCePt studiO 520C)

If, due to speaker placement or your room's acoustics, you feel that the speakers produce a bit too much bass output

for your taste, you can use the provided port tube inserts to slightly reduce the speakers' output in the 50Hz – 100Hz

region.

Insert the port tube insert about half way into the port tube opening as shown in the illustration. Be careful not to push

the insert through the port tube and into the speaker cabinet.

NOTE: The Studio 590 has two port tubes and includes two port tube inserts.
