A summary of the advantages and disadvantages of a single and multiple subwoofer systems is shown in the
table below:
Advantages
Single subwoofer Lower cost
systems Less total space required
Might be easier to setup
Consistent acoustic summing in the
Multiple subwoofer Multiple smaller cabinets may be easier to
systems
Suppression of side wall interactions
Suppression of room resonances (PWBA™)
See the Volume Control section for details on how to control multiple subwoofer systems.
Interconnection Examples
In the following interconnection diagrams, O 300 and O 810 have been shown as examples. Other products from
the Klein + Hummel range can be substituted, for example O 410 and O 870. Please refer to the "K+H Product
Selection Guide" for building balanced systems.
From the above wiring diagram it is easy to see that the 7.1 High Definition Bass Manager™ can also be used for
1.0, 2.0, 3/1.0, 5.0, 5.1, 6.0, 6.1, and 7.1 (theatrical) signals.
A less obvious but very useful configuration is also possible. A 5.1 signal can be connected as shown in the
diagram below. In addition, the two unused back channels can be connected to a separate 2.0 signal and the
subwoofer used to give bass extension to a second pair of loudspeakers. Note that the additional pair of
loudspeakers should be placed the same distance as the 5.1 system's main loudspeakers so that the phase
setting on the subwoofer remains valid for both systems. Different listening distances will require different phase
settings.
