Troubleshooting
Symptom Description Solution
A “chuffing” sound
is coming from the
subwoofer. Distortion due
to port tube
placement Check the placement of the port
tube. Move the tube opening slightly
away from the grille surface to reduce
distortion.
This reduces the output level
slightly
, a trade-off that must be
managed.
Distortion due
to overdriven
subwoofer Attenuate the signal to the subwoofer.
If the desired sound pressure level
cannot be achieved at the new setting,
consider relocating the subwoofer
to a more favorable location (for
example, edge or corner mounting —
see
Acoustical Reinforcement on
page 5) and swapping fiberglass
tiles (if used) for mineral tiles.
If the desired sound pressure level still
cannot be met, then the listening space
requires more subwoofers.
