Phil Jones Bass DP-1 Owner's Information page 3

If you are using a receiver/processor with a THX® surround mode and have
selected the THX surround mode, it may be beneficial to use the Dipole setting.
This is a matter of personal preference and may change depending on the
individual film soundtrack. It is also recommended that the Dipole setting be used
with older recordings that are only recorded with a Dolby® Pro Logic® (not the
newer Dolby Digital) soundtrack.
Placement (Application 2)
When using the DP-1 as a rear speaker(s) in a 7-channel home theater system,
refer to Figure 2. The speaker(s) should be mounted on the rear wall facing the
listening area, between the side channel speakers.
If you are using one rear speaker, it should be mounted as close as possible to
the center of the listening area. When using two rear speakers, they should be
spaced evenly within the width of the listening area.
Setting the Surround Configuration Selector
When used as a rear channel speaker in a 7-channel system, it is
recommended that the Surround Mode Configuration Switch be set to Bipole.
