s Manual

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.

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.

•  Highly reverberant rooms, like many gymnasiums

    and auditoriums, are a nightmare for sound    
    system intelligibility. Multiple reflections off the  
    hard walls, ceiling and floor play havoc with the  
    sound. Depending on the situation, you may    
    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.
