the bass management is used. Checking the multichannel mix with this setting on lets you know how it
translates in systems with this limitation.
The 10 Hz LFE bandwidth setting complies with the replay systems of movie theaters and cinemas.
5 mm movie soundtracks use the LFE channel to reproduce a bandwidth of 0 - 10 Hz through
dedicated subwoofers. In this case the LFE and main channel bandwidths overlap between 85 and 10
Hz, which may create unwanted acoustical summing if the same signal is present in both channels. To
avoid this, the LFE content should be kept completely different (de-correlated) from the low frequency
content of the main channels when mixing music and sound effects for film release.
Maintenance
No user serviceable parts are to be found within the subwoofer enclosure. Any maintenance or repair of
the loudspeaker should be undertaken by qualified service personnel only.
