Overview
EVOi.324 has been designed to be permanently installed. An eyebolt kit has been provided to facilitate suspension from above: a ceiling, a beam or overhang. EVOi.324 weighs 65 pounds (29.5 Kg) and attaching this loudspeaker to a surface is a task that should not be taken lightly. Always consult a qualified person.
Suspension
WARNING !! Suspending this system should be done by qualified persons following safe rigging standards. For more information, please refer to the JBL Technical Note Volume 1, Number 14 – Basic Principles for Suspending Loudspeaker Systems.
For Example: Maximum Load Rating divided by EVOi.324 Net Weight = The number of speakers in a vertical array.
142.8 lb (67.8 Kg) / 65 lb (29.5 Kg) = 2.1
Therefore only two EVOi.324s may be used in a vertical array if they are suspended from the points located on the top of the enclosure in either recommendations 1 and 2 stated above.

1Suspension Advisory and Tech Note
Before suspending an EVOi.324, be sure to inspect all components for cracks, deformations, corrosion, and/or missing or damaged parts that could reduce the strength and safety of the installation.
Perform all calculations to ensure that all components are used within their rated work load before suspending an EVOi.324. Remember the weakest component determines the size and safety of the entire installation.
There are 3 suspension points on the top and bottom of EVOi.324, two toward the front of the enclosure and one to the rear. Pull tests at a certified test facility have docu- mented
Installing Eyebolts:
1.Remove suspension placeholder screws.
2.Coat each eyebolt with
3.Using the included washers as

Figure 25 - Remove Placeholder Bolts
It is recommended that EVOi.324 be either suspended:
1.Equally from both of the front suspension points together, or
2.From the rear suspension point, with the addition of a safety cable to another suspension point.
For both recommendations, assuming a 7:1 safety factor, the load on the suspension points should NEVER be greater than 142.8 pounds (67.8 Kg).
