Placement

The S500 Series loudspeakers are designed to sit on the floor or stage. The S512 and S515 may also be pole- mounted via the built-in socket on the bottom of the cabinet. Be sure the pole is capable of supporting the weight of the loudspeaker. The S525 and S518S are NOT designed to be pole-mounted.

WARNING: These cabinets have no rigging points and are not suitable for rigging.

NEVER attempt to suspend any S500 Series loudspeaker by its handles.

As with any loudspeakers, protect them from moisture. If you are setting them up outdoors, make sure they are under cover if you expect rain.

Room Acoustics

The S500 Series loudspeakers are designed to sound as neutral as possible. However, room acoustics play

a crucial role in the overall performance of a sound system. Here are some placement tips to get the best performance from the S500 Series loudspeakers:

•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 loudspeakers directly on

a hollow stage floor. A hollow stage can resonate at certain frequencies, causing peaks and dips in the frequency response of the room. It is better to place the loudspeakers on a sturdy table or tripod stands.

•Position the loudspeakers so the high-frequency drivers are a foot or more 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 loudspeakers to

the audience, you increase the overall brightness and intelligibility of the sound system.

be able to take some steps to minimize the

 

reflections, such as putting carpet on the floors,

 

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 reflections 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 loudspeaker, the more

 

prominent will be the reflected 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 100 feet, you should be able to use a

 

delay processor to time-align the sound. Since

 

sound travels about one foot per millisecond, it

 

takes 1/10 of a second to travel 100 feet.
