when toed-in. This design gives you the flexibility to 
compensate for a soft or bright room.
Generally it is found that the ideal listening position 
is with the speakers slightly toed-in so that you are 
listening to the inner third of the curved transducer 
section. A simple, yet effective method to achieve 
proper toe involves sitting at the listening position, 
holding a flashlight under your chin and pointing 
it at each speaker. The reflection of the flashlight 
should be within the inner third of the panel (see 
figure 7).
Imaging
In their final location, your EM-ESL X ’s can 
have a stage width somewhat wider than the 
speakers themselves. On well recorded music, 
the instruments can extend beyond the edges of 
each  speaker (left and right), yet a vocalist should 
appear directly in the middle. The size of the 
instruments should be neither too large nor too 
small, subject to the intent and results of each 
unique audio recording.
Additionally, you should find good clues as to 
stage depth. Make sure that the vertical alignment, 
distance from the front wall, and toe-in is exactly 
the same for both speakers. This will greatly 
enhance the quality of your imaging.
Bass Response
Your bass response should neither be one note 
nor should it be too heavy. It should extend to 
the deepest organ passages and yet be tight 
and well defined. Kick-drums should be tight and 
percussive—string bass notes should be uniform 
and consistent throughout the entirety of the run 
without booming or thudding.
Tonal Balance
Voices should be natural and full and cymbals 
should be detailed and articulate yet not bright 
and piercing, pianos should have a nice transient 
characteristic and deep tonal registers. This will give 
you clues on how to get closer to these ideal virtues.
FINAL PLACEMENT
After the full break in period, obtaining good wall 
treatments, and the proper toe-in angle, begin to 
experiment with the distance from the wall behind 
the speakers Move your speaker slightly forward 
into the room. What happened to the bass 
response? What happened to the imaging? If the 
imaging is more open and spacious and the bass 
response is tightened, that is a superior position. 
Move the speakers back six inches from the initial 
setup position and again listen to the imaging and 
bass response. There will be a position where 
you will have pinpoint imaging and good bass 
response. That position is the point of the optimal 
placement from the front wall.
Now experiment with placing the speakers farther 
apart. As the speakers are positioned farther apart, 
listen again, not so much for bass response but 
for stage width and good pinpoint focusing. Your 
ideal listening position and speaker position will 
be determined by:
• Tightness and extension of bass response
• Width of the stage
• Pinpoint focusing of imaging
Once you have determined the best of all three 
of these considerations, you will have your best 
speaker location.
THE EXTRA “TWEAK”
This extra “tweak” may be useful when your 
speakers are placed in a dedicated listening room. 
Use the  following procedure and measurements 
for your speakers  placement to see what can 
happen to your system’s performance. These 
formulas will help determine optimum  placement 
of your speakers to minimize standing waves.
