SUBWOOFER PLACEMENTS
A powered subwoofer delivers crucial impact in a home
theater system although it is one of the least demanding
speakers to position. Since low bass frequencies are omni-
directional, you can usually place your subwoofer just about
anywhere in your home theater room and still get good results.
Placing your subwoofer near a wall will generally produce
more output due to wall reflection. Moreover, if you place your
subwoofer in the corner, the output is maximized even moire.
Keep in mind that even though the bass increases as you place
the sub near a wall or corner, the quality of bass may be slightly
"boomier" and less controlled. Thus, aim for a spot where you get
a compromise between quality and quantity of bass.
One cool technique for placing for your subwoofer is to put
your sub in your listening spot (i.e. on your sofa), play some
music, move around the room, and listen. Be sure that you bend
down closer to the floor as you walk as this will lead to more
accuracy as to what you will get. You will probably notice that the
bass sounds a little bit different as you move around the room
from one location to another. When you reach a spot where the
bass sounds best, that may be the location where you want to
place the subwoofer.
After finding the best subwoofer placement, you will need to
set the phase. Earthquake subwoofers are equipped with 0° -
180° phase control switch. Simply play one of your favorite
songs and switch the phase control back and forth. You may
need assistance from a friend or family member. Choose the
setting that produces the most bass while all your speakers are
playing.
Subwoofers have slower responses compared to the rest of
the speaker systems. This is strictly Physics. The CP-8 is
designed to address this issue. By making the CP-8 slim in
profile, it opens up more placement options (i.e. under or behind
the sofa, vertically standing against the wall in the corner of the
room, etc.) to offset the response delay.
Figure 6 through 9 illustrate the bass response in the room
when placing the CP-8 in different location of the room.
