16 Frequently Asked Questions

How do I clean my speaker?

Use a dust free cloth or a soft brush to remove the dust

from your speaker. We also recommend a specialty

cloth (available at the Xtatic shop at www.martinlogan.

com) that cleans your speaker better than anything else

we have tried. For the wood surfaces it is acceptable to

slightly dampen the cloth. Do not spray any kind

of cleaning agent on or in close proximity

to the electrostatic element. Avoid the use of

ammonia based products or silicone oil on

the wood parts.

What is the advantage of ESL?

Since the diaphragm is uniformly driven over its entire

surface—unlike a tweeter that is only driven at its

edges— it is the only technology that can be made

large enough to play bass, yet is still light enough for

high frequencies. This unique property allows for the

elimination of high frequency crossover points and their

associated distortions.

What size amplifier should I use?

We recommend an amplifier with 100 to 250 watts

per channel for most applications. Probably less would

be adequate for our smaller hybrids or when used in

home theater where a subwoofer is employed. Our

hybrid designs will perform well with either a tube or

transistorized amplifier, and will reveal the sonic char-

acter of either type. However, it is important that the

amplifier be stable operating into varying impedance

loads: an ideally stable amplifier will typically be able

to deliver nearly twice its rated wattage into 4 Ohms

and should again increase into 2 Ohms.

Could you suggest a list of suitable elec-

tronics and cables that would be ideal for

MartinLogan speakers?

The area of electronics and cable choice is probably

the most common type of question that we receive. It

is also the most subjective. We have repeatedly found

that brands that work well in one setup will drive some-

one else nuts in another. We use many brands with

great success. Again, we have no favorites; we use

electronics and cables quite interchangeably. We

would suggest listening to a number of brands—and

above all else— trust your ears. Dealers are always the

best source for information when purchasing additional

audio equipment.

Is there likely to be any interaction between my

speaker and the television in my Audio/Video

system?

Actually, there is less interaction between a television

and an electrostatic speaker than between a television

and a conventional system. However, we generally rec-

ommend that you keep your speaker at least one foot

away from the television because of the dynamic woof-

er they employ. In the case of the Feature, however,

they are fully shielded and can go anywhere.

Will my electric bill go ‘sky high’ by leaving my

speaker plugged in all the time?

No. A pair of MartinLogan’s will draw about 8 watts

maximum (idle). There is circuitry to turn off the static

charge when not in use; however, actual consumption

will remain close to the same. The primary purpose of

the sensing circuitry is to prevent dust collection on the

electrostatic element.

If the diaphragm is punctured with a pencil or

similar item, how extensive would the damage

to the speaker be?

Our research department has literally punctured hundreds

of holes in a diaphragm, neither affecting the quality of

the sound nor causing the diaphragm to rip. However,

you will be able to see the actual puncture and it can

be a physical nuisance. If this is the case, replacing the

electrostatic transducer will be the only solution.

Will exposure to sunlight affect the life or per-

formance of my speaker?

We recommend that you not place any loudspeaker

in direct sunlight. The ultraviolet (UV) rays from the sun

can cause deterioration of grill cloth, speaker cones,

etc. Small exposures to UV will not cause a problem.

In general, the filtering of UV rays through glass will

greatly reduce the negative effects on the electrostatic

membrane itself.
