This rule suggests that a little reflection is good.

As a matter of fact, some rooms can be so “over

damped” with carpeting, drapes and sound

absorbers that the music system can sound dull and

lifeless. On the other hand, rooms can be so hard

that the system can sound like a gymnasium with

too much reflection and brightness. The point is

that balance is the optimum environment.

Breakup Objects

Objects with complex shapes, such as

bookshelves, cabinetry and multiple shaped walls

can help break up those sonic gremlins and diffuse

any dominant frequencies.

DIPOLAR SPEAKERS AND YOUR ROOM

MartinLogan electrostatic loudspeakers are known

as dipolar radiators. This means that they produce

sound from both their fronts and their backs.

Consequently, musical information is reflected by

the wall behind them and may arrive, either in or

out of step, with the information produced by the

front of the speaker.

The low frequencies can either be enhanced or

nulled by the position from the front wall. Your

EM-ESL X’s have been designed to be placed two

to three feet from the front wall (the wall in front

of the listening position) to obtain the best results;

however, your room may see things differently. So

listening to the difference of the bass response as a

result of the changes in distance from the front wall

can allow you to get the best combination of depth

of bass and tonal balance.

Now that you know about reflective surfaces and

resonant objects, you can see how the midrange

and high frequencies can be affected. The timing

of the initial wave as it radiates to your ears, and

then the reflected information as it arrives at your

ears later in time, can result in confusion of the

precious timing information that carries the clues

to imaging. Consequently the result is blurred

imaging and excessive brightness. Soft walls,

curtains, wall hangings, or sound dampeners (your

dealer can give you good information here) can

be effective if these negative conditions occur.

SOLID FOOTING

After living and experimenting with your EM-ESL

X speakers, you may want to expose the ETC

(energy transfer coupler) Spikes (see figure 8).

With the use of these spikes, the EM-ESL X will

become more firmly planted on the floor and,

consequently, bass will tighten and imaging will

become more coherent and detailed. It is best not

to use the spikes, however, until you are secure in

the positioning, as the spikes can damage the floor

if the speaker is moved.

Exposing the Spikes

Remove the rubber bumpers to expose the spikes

(see figure 6). If the speaker does not sit level loosen

one spike until level is achieved. Caution: Make

sure your hands and any cabling are clear of the

spikes. Do not slide speaker as spikes are sharp

and can damage your floor or carpet. Caution:

Walking the speaker may result in a broken spike.
