Placing Your Fathom in Your Listening Room

PLACING YOUR FATHOM 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, all is not lost. Your Fathom’s Automatic Room Optimization (A.R.O.) System can dramatically improve these less-than-ideal situations.

We recommend that you begin by placing your Fathom 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 Fathom’s A.R.O. system can correct the primary peak 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 Fathom 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 Fathom near windows to prevent rattling and sound transmission to the outside world.

If you are planning to install your Fathom inside a cabinet, please refer to the guidelines on page 8.
