Sound Measurement Guidelines - REVELL Performa B15 Owner's Manual

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 PERFORMA B15
subwoofer 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. If the installation allows, choose the prime listening
position so it is away from the exact center of the room's width.
This will generally result in smoother low frequency sound.
• 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.
