PLACING YOUR GOTHAM v2 IN YOUR LISTENING ROOM:

Your listening room or theater is an integral part of your sound reproduction
system. The physical dimensions of the room and its furnishings, materials, doors
and windows play an important role in defining how your system sounds.
When you place a sound source in an enclosed rectangular space, "standing
waves" are created, resulting from the relationship between the sound's
wavelength and your room's dimensions. In other words, standing waves result
from sound energy that is trapped in the room as it bounces back and forth
between opposing walls. Standing waves in the room create acoustic peaks and
dips where the sound is either louder or softer, based solely on your physical
position in the room. Energy also "builds up" at the room's boundaries, creating
exaggerated bass response at certain frequencies. These fundamental room
resonances are called room "modes."
The moral of this mode story is to try and avoid seating positions in standing
wave peak or dip regions. It is highly recommended that you place your listening
chairs in areas where modal peaks and dips are moderate and do not reinforce
one another. The two most obvious areas to avoid are those near the exact center
of the room and those close to any of the room's walls.
Just as your listening seat can be in a peak or dip region, so can your
subwoofer. When placed in a room corner, a subwoofer maximally excites the
room's mode structure, creating the strongest output with the fewest dips. When
the subwoofer is pulled away from a corner or wall, the room modes are excited
less, which can alter the sound at your listening seat.
Be sure to experiment with both your listening seat position and subwoofer
position to find the best solution. Careful experimentation usually leads to a
superior sounding system. Use our setup suggestions (illustrated on the opposing
page and the following pages) to get you started.
If you cannot avoid placing your sofa against the back wall, or your subwoofer
in a less than optimal position, your Gotham v2's Digital Automatic Room
Optimization (D.A.R.O.) System can dramatically improve these less-than-ideal
situations.
We recommend that you begin by placing your Gotham v2 in the front
of the room, near the front left or right speaker. Placing it directly in the
front corner of the room will produce the maximum number of peaks and
the minimum number of dips in the bass response. This can be advantageous
because the Gotham v2's D.A.R.O. system can correct the resulting peaks very
effectively, whereas dips in response cannot be corrected via equalization. Dips in
response can only be minimized via careful subwoofer and listener placement.
Placing the Gotham v2 near solid walls will reinforce bass response and
pulling it away from solid walls will decrease bass. Increasing the distance
between the subwoofer and the walls may help to smooth upper bass response in
some rooms.
We recommend that you avoid placing the Gotham v2 near windows to prevent
rattling and sound transmission to the outside world.
SPECIAL CONSIDERATIONS FOR HANDLING THE GOTHAM v2
The Gotham v2 is extremely heavy and can be difficult to handle. Failure
to handle it correctly during unpacking and placement can result in expensive
damage which is not covered under warranty.
