Loudspeakers are ideal for adding music to an outdoor event. However, when set up outdoors, speakers are naturally more prone to problems. First of all, the outdoor environment is a fairly harsh environment depending on where you live. Some areas have very high humidity or heat. Especially rainfall can cause lots of problems.
In I will give you some tips for making sure that you speakers will survive when used outdoors. First of all, I recommend selecting speakers which were qualified by the manufacturer for outdoor use. Usually outdoor speakers have a suitable enclosure that doesn’t get damaged when exposed to rainfall. In that case, the control elements such as volume controls and indicators if there are those will usually be covered by a membrane.
In addition to the speakers, make sure that any sort of mounting hardware that you use for installation is rustproof. You don’t want a mounts to fail because as a result the speaker can get damaged. Also, rust can easily transfer between a mount and the speaker.
Also, try to set up the speaker fairly high in order to prevent dirt from entering the enclosure. You don’t want any part of the speaker to make contact with the ground. Also, I recommend keeping any speaker wires fairly short. Long exposed speaker wires can cause a trip hazard and also can attract lightning.
If the speaker itself is not suitable for closure to rainfall, you can alternatively mounted underneath a roof or build a small cover to protect it. However, when building a cover make sure that the sound can still radiate freely from the speaker. Some outdoor speakers are omnidirectional. That means that sound can travel in all directions equally. Traditional speakers, on the other hand, are designed such that the high frequencies will travel specifically in one direction. When designing the enclosure make sure you don’t block any acoustic vents of the speaker.
In addition, try to locate the speaker away from direct sunlight because excessive heat can damage components inside the speaker as well as the enclosure. Also, make sure that you don’t over drive the speakers by selecting an amplifier which is too powerful.
