SUPERNOVA MKIV OWNER’S MANUAL
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
omnidirectional, 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 more. 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 or movies, 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. We recommend placing the
subwoofer with the active driver facing the listening while
the passive faces the wall or corner.
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 or movie scenes 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.
