Revel sub30 사용자 가이드

•

The placement of the other system loudspeakers in the listening
room system will also affect the way sound (below 300 Hz) is
reproduced. Just as is the case with subwoofers, use a modeling
program or trial-and-error measurements to determine the 
best locations.

•

Since listening and loudspeaker locations are equally important,
the trial-and-error process can be time-consuming. However,
the sonic rewards are great. Remember that peaks (below the
subwoofer crossover frequency) can be eliminated by the proper
adjustment of the REVEL ULTIMA SUB 30’s EQ controls,
but most dips cannot be corrected. Therefore, the most impor-
tant objective is to find locations that result in the minimum
number and severity of dips. 

SOUND MEASUREMENT GUIDELINES

•

If you are using a modeling program, begin by placing the
microphone at ear height at the recommended listening posi-
tion, with the subwoofer placed at the calculated position.
Choose a location that has been used for listening in the past.
Otherwise, select a location that is most desirable for aesthetic
or other considerations. If the locations are to be determined
by trial-and-error, begin with one REVEL ULTIMA SUB 30
in a front corner of the room (nearest the main loudspeakers). 

•

As a starting point, avoid selecting listening locations that are
near the middle, or at one-quarter or three-quarters of the
room’s length (front-to-back), where large cancellation dips
often occur. 

•

Use care when locating the listening position away from the
center of the room’s width, as imaging characteristics may be
degraded. Off-center locations will usually work only when the
side walls are acoustically treated with absorbent materials, or
if the room is exceptionally wide. 

•

For best results, use a camera tripod with a Sound Level Meter,
or a microphone stand for the microphone.
