Paradigm UltraCube 12 - Manuel (Page 7)

When using two subwoofers, placing one in the front of the room and the
other in the rear of the room (as shown in Fig. 2) usually provides the best
bass performance and sonic integration. Consult the fine tuning section of
the Owner’s Manual for more information on adjusting phase settings.
If
those locations are not possible or if you want to experiment with placement
options using two subwoofers, the following procedure will be a helpful guide
to achieving better bass performance. Refer to “Subwoofer Connection” then
proceed as follows:
1. Temporarily turn all speakers off (either by turning your amplifier off or
disconnecting them);
2. Connect and place one subwoofer in the central area of your listening room.
Follow directions for connection, as outlined in the following section;
3. At a moderately loud level, play music or a video soundtrack with
extended bass that is repetitive or continuous;
4. Walk around your room and note where the bass sounds louder and
where it sounds quieter;
5. Place the first subwoofer within a louder bass area of your room; then
place the second subwoofer within a quieter bass area of your room;
6. Connect both subwoofers and switch all speakers back on; and switch
the amplifier on, or reconnect it;
7. Follow “Fine Tuning” instructions on page 8, to optimize your system’s
overall bass performance.

NOTE: The preceding is only a guideline. You may want to use a
bass test disc and SPL meter to more accurately determine the bass
characteristics of your listening room (see Dealer for more information). Remember that room acoustics vary so it may take some experimenting
with placement to achieve the best subwoofer performance.

hooking up your subwoofer (see Dealer).
IMPORTANT: It is important that you become familiar with your powered
subwoofer’s Input/Output Facilities and Control Facilities. Before connecting
your subwoofer, read the following sections. Facilities vary by model. Inspect your subwoofer’s rear panel and check
