YOUR ROOM
This is one of those areas that requires both a little 
background to understand and some time and 
experimentation to obtain the best performance 
from your system.
Your room is actually a component and an important 
part of your system. It can dramatically add to, or 
subtract from, a great musical experience.
All sound is composed of waves. Each note 
has its own wave size, with the lower bass 
notes literally encompassing from 10’ feet to as 
much as 40’ feet. Your room participates in this 
wave experience like a three dimensional pool 
with waves reflecting and becoming enhanced 
depending on the size of the room and the types 
of surfaces in the room. Remember, your audio 
system can literally generate all of the information 
required to recreate a musical event in time, 
space, and tonal balance. Ideally, your room 
should not contribute to that information. However, 
every room does contribute to the sound to some 
degree. Fortunately MartinLogan had designed the 
EM-ESL X to minimize these anomalies.
TERMINOLOGY
Standing Waves
The parallel walls in your room will reinforce 
certain notes to the point that they will sound louder 
than the rest of the audio spectrum and cause “one 
note bass”, “boomy bass” or “bloated bass”. For 
instance, 100Hz represents a 10 feet wavelength. 
Your room will reinforce that specific frequency if 
one of the dominant dimensions is 10 feet. Large 
objects in the room such as cabinetry or furniture 
can help to minimize this potential problem. Some 
serious “audiophiles” will literally build a special 
room with no parallel walls just to help eliminate 
this phenomenon.
Reflective Surfaces (near-field reflections)
The hard surfaces of your room, particularly if close 
to your speaker system, will reflect some waves 
back into the room over and over again, confusing 
the clarity and imaging of your system. The smaller 
sound waves are mostly affected here, and occur in 
the mid and high frequencies. This is where voice 
and frequencies as high as the cymbals occur.
Resonant Surfaces and Objects
All of the surfaces and objects in your room are 
subject to the frequencies generated by your 
system. Much like an instrument, they will vibrate 
and “carry on” in syncopation with the music, and 
contribute in a negative way to the music. Ringing, 
boominess, and even brightness can occur simply 
because they are “singing along” with your music. 
Resonant Cavities
Small alcoves or closet type areas in your room can 
be chambers that create their own “standing waves” 
and can drum their own “one note” sounds.
Clap your hands. Can you hear an instant echo 
respond back? You have near-field reflections. 
Stomp your foot. Can you hear a “boom”? You 
have standing waves or large panel resonances 
such as a poorly supported wall. Put your head in a 
small cavity area and talk loudly. Hear a booming? 
You’ve just experienced a cavity resonance.
RULES OF THUMB
Hard vs. Soft Surfaces
If the front or back wall of your listening room 
is soft, it might benefit you to have a hard or 
reflective wall in opposition. The ceiling and floor 
should follow the same basic guideline as well. 
However, the side walls should be roughly the 
same in order to deliver a focused image.
