General advice includes: 

 

Ensure the stand is not placed where it will be a trip hazard 

 

Ensure the stand is rated to take the weight of the speaker comfortably 

 

Ensure the legs are splayed out sufficiently to prevent toppling 

 

17. Loudspeaker cables 

From a rigging perspective, there are a number of points to consider regarding loudspeaker 
cables: 

1.

 

The “self” weight of the cable must be factored in to the total load to be flown. 
Some typical cable weights are listed below for illustration: 

Cable type 

Connector type 

Typical  weight  per 
metre (grams) 

2 x 2.5mm² (14AWG) 

NL4 

122 (0.269 lbs) 

2 x 4.0mm² (12 AWG) 

NL4 

162 (0.357 lbs) 

4 x 2.5mm² (14AWG) 

NL4 

160 (0.353 lbs) 

4 x 4.0mm² (12AWG) 

NL4 

260 (0.573 lbs) 

8 x 2.5mm² (14AWG) 

NL8 

350 (0.772 lbs) 

8 x 4.0mm² (12 AWG) 

NL8 

500 (1.102 lbs) 

E.g. For a system comprising an IF3115, 10 metres of 8 x 4.0mm² cable would add an 
additional 5kg of weight per speaker. 

2.

 

Cable management is necessary to ensure the cabling is held securely, and neatly in 
place, and that the cable is not under any strain, which may cause damage to the 
connections, undesired positioning or movement of the system. 

3.

 

Never use a loudspeaker cable for “tying off” – the purposes of preventing the system 
from rotating. 

 

18. Commonly used rigging accessories 

 

Here are some examples of rigging accessories which may prove useful in providing solutions 
to common problems encountered in rigging the Installation Series speakers in a variety of 
environments: 

 

Wedge sockets 

 

Bullets 

 

Rigging screws 

 

Hanging clamp 

 

STAC chain 

 

RUD Adjustable chain sling 

 

Bridles 

 

Master links / O links 

 

Shackles 

 

Wire rope slings 

 

Girder clamps 

 

Load Rated Karibiner 

 

Custom brackets
