Revel Performa3 M105 Manual Do Proprietário

Loudspeaker fidelity depends on the following three factors: loudspeaker 
accuracy, loudspeaker placement and listening room acoustics.

Advanced Revel design features allow the M106 and M105 to achieve 
exceptional acoustical precision. As a result, experimenting with 
loudspeaker placement and listening room acoustics will have the most 
significant impact on the loudspeakers’ performance.

The following are important loudspeaker placement considerations for 
the M106 and M105:

 

•  Remove all obstructions between the loudspeaker and the 

primary listening position. For instance, a coffee table between 
the loudspeaker and the primary listening position will create 
reflections that will degrade stereo imaging and timbre. Placing 
the loudspeakers near large objects may also cause unwanted 
reflections.

 

•  For the best stereo imaging, place the loudspeakers so that they are 

both the same distance from the primary listening position and so 
they are both the same distance from the side walls, as shown in 
the illustration below.

Primary Listening Position

 

•  For optimal stereo imaging and timbre, aim the loudspeakers 

almost directly toward the primary listening position as shown in 
the illustration above. If you wish to widen the stereo soundstage 
you can reduce this toe-in angle, even to the point at which the 
loudspeakers are pointing straight forward.

 

•  Moving the loudspeakers farther from the front and side listening 

room walls will improve stereo imaging and the sense of 
spaciousness in the listening space.

 

•  Moving the loudspeakers closer to the corners or walls of the 

listening room will increase bass response.

 

•  For best results, place the speaker so the tweeter is aligned with a 

seated listener’s ears, approximately 36" (91cm) above the floor.

•  Optional Performa3 M Stand pedestal stands are available for 

the M106 and M105 that place the speakers at the proper height 
for seated listeners. Refer to the assembly instructions that are 
included with the stands for additional information.

Listening rooms have a profound impact on sound, particularly 
at lower frequencies. In fact, the effect of the listening room can 
dominate sounds below about 400Hz. Ideally, listening rooms would 
include optimized dimensional ratios to minimize the effects of room 
resonances. But in reality, most listening rooms are not designed to 
enhance loudspeaker performance.

The interaction between loudspeakers and listening rooms is complex, 
with two important determinants that affect the loudspeaker and the 
listener:

 

•  Surfaces and other boundaries often cause large peaks and dips 

in low-frequency response. These peaks and dips can often range 
12dB or more.

 

•  Standing waves (also known as room modes or resonances) interact 

with both the loudspeaker and the listener, resulting in large errors 
in frequency response.

Unfortunately, there is no simple solution that addresses both of 
these factors. Even computer software programs that examine one 
or both factors may not calculate proper primary listening position or 
loudspeaker placement values.

In most cases, proper selection of the primary listening position 
combined with proper placement of the loudspeaker can result in 
superior performance at lower frequencies. The difference between 
superior and inferior results is often just a small adjustment of the 
primary listening position or loudspeaker placement. Contact your
