Here are some useful placement tips:

• Avoidplacingloudspeakersinthecornersofaroom.

This increases the low-frequency output and can cause

the sound to be muddy and indistinct.

• Avoidplacingloudspeakersagainstawall.This,too,

increases the low-frequency output, though not as

much as corner placement. However, if you do need to

reinforce the low frequencies, this is a good way to do it.

• Avoidplacingtheactivespeakersdirectlyona

hollowstageoor.Ahollowstagecanresonateat

certain frequencies, causing peaks and dips in the

frequency response of the room. It’s better to place the

active speakers on a sturdy table or tripod stands.

• Positiontheactivespeakerssothehigh-frequency

drivers are 2 to 4 feet above ear level for the audience

(make allowances for a standing/dancing in the aisles

audience). High frequencies are highly directional and

tend to be absorbed much easier than lower

frequencies.Byprovidingdirectline-of-sightfromthe

active speakers to the audience, you increase the

overall brightness and intelligibility of the sound

system.

• Highlyreverberantrooms,likemanygymnasiumsand

auditoriums, are a nightmare for sound system

intelligibility.Multiplereectionsoffthehardwalls,

ceiling,andoorplayhavocwiththesound.Depending

on the situation, you may be able to take some steps

tominimizethereections,suchasputting

carpetingontheoors,closingdraperiestocoverlarge

glass windows, or hanging tapestries or other materials

on the walls to absorb some of the sound.

However, in most cases, these remedies are not possible

or practical. So what do you do? Making the sound

system louder generally doesn’t work because the

reectionsbecomelouder,too.Thebestapproachisto

provide as much direct sound coverage to the audience

as possible. The farther away you are from the speaker,

themoreprominentwillbethereectedsound.

Use more speakers strategically placed so they are

closer to the back of the audience. If the distance

between the front and back speakers is more than

about 100 feet, you should use a delay processor to

time-align the sound. (Since sound travels about 1 foot

per millisecond, it takes about 1/10 of a second to travel

100 feet).
