Sound Optimisation - Use of bungs
A pair of bungs is supplied with the X300A Wireless system for you to ne-tune the bass output. When the
speakers are positioned close to the wall, it is recommended that the bungs be placed into the rear port if
you nd the bass output to be overwhelming or boomy.
2. Full bung
For more bass reduction, you may put the full bung
into port.
It is recommended that you try the different bung
configuration to achieve the most optimal sound
output for your environment.
1. Outer bung only
The bung can be separated into outer and inner
bungs. The use of the outer bung only will give less
bass reduction.
