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 hol-

low stage floor. 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  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 frequen-
cies. 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 intel-
ligibility. 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 mini-
mize the reflections, such as putting carpeting 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 speaker, 
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 be-
tween 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 mil-
lisecond, it takes about 1/10 of a second to travel 100 
feet).

RIGGING

The SRM50 v cabinets are fitted with four M5 insert 
points on the top and bottom for installing an optional 
hanging bracket that allows the speaker to be flown. 

SRM350 Bracket Kit: Part No. 0016404

WARNING:

 Never attempt to suspend 

the SRM50 v active speakers by their 
handles. If you want to suspend them, 
use the hanging brackets only.

If you are hanging them in an inaccess-
able place, such as over a lion’s cage, 
make sure that you first complete the 
sound check and set the SRM50 v 
LEVEL correctly.
