Speaker And Room; Bass Management - Lyngdorf Audio MP-50 Owner's Manual

The purpose of the speaker setup is to tell the system which speakers and subwoofers are
available and how big they are, which in turn reveals how much bass they are capable of
reproducing. References to "speakers" in this document are specific to "normal" speakers and
do not include subwoofers.

Speaker Cutoff Frequency
For all the speakers in the system, a size must be chosen. The speaker size informs the system
how much bass the speaker is capable of playing by selecting a cutoff frequency. Signals below
this frequency will then be redirected to another speaker or subwoofer in the system.
Available selections for speaker size are:
•
None (The output is unused)
•
XXL (Plays full range signal and LFE channel if no subwoofer is connected)
•
XL (Plays full range signal)
•
L (Cutoff frequency 40Hz)
•
M (Cutoff frequency 80 Hz)
•
S (Cutoff frequency 100Hz)
•
XS (Cutoff frequency 120Hz)
•
Custom (User selectable cutoff frequency)
Which cutoff frequency should you choose?
When selecting a cutoff frequency for your speakers, you should select a frequency higher than
the lowest frequency your speaker is specified to play.
If the redirected bass will be played by a subwoofer (and not a full range speaker), you should
also make sure that the cutoff frequency is lower than the highest frequency the subwoofer can
play.
XL Speakers
Selecting the speaker size as XL will designate the speaker as capable of playing a full range
signal.
The system can only redirect bass to XXL speakers placed at the Left Front/Right Front, Left
Surround/Right Surround, and Left Rear Surround/Right Rear Surround positions.
In a system with front/rear subwoofers present, there will be no difference between XL and
XXL, since the redirected bass is played by the subwoofers instead.
In a system with an LFE sub, the LFE sub will play the LFE channel, while the XXL speakers
will play the redirected bass. (LFE is a separate channel for Low Frequency Effects)
In a system with no subwoofers at all, the XXL speakers will play the redirected bass as well as
the LFE channel.
Normally a system without any subwoofers will need to have XXL speakers to receive LFE and
redirected bass. There is, however, one exception; it is possible to make a system without
