Natural roll-off
When natural roll-off is used, the main speaker will receive the full range signal and will be
allowed to roll-off naturally. The bass cutoff frequency will still be used to send the bass to a
subwoofer or XXL speaker, but it will not be applied to the main (high pass) output.
Assignment of speakers to bass positions
When XXL or front/rear subwoofers are used, the redirected bass from speakers will be
distributed to the left or right side, and when rear subwoofers or XXL surround or rear speakers
are involved, it will also be distributed between front and rear. This table shows where each
speaker has their bass directed to in these situations.

Bass management examples
The following examples show some different setups and how bass is routed. The examples
only mention where the LFE channel and the redirected bass is played; the high frequency part
of any channel is always played by the speaker for that channel. The same goes for bass that is
not redirected, so this is not specifically mentioned.
