Any line array rigging experts here please?

Welcome newbie, feel free to post your question along with details. I can't help you with that, but there are many experts here!! HA. I'm sure others will answer. Until then you can simply search "line array" above in the archives. Much come's up. 

Try DIYaudio

I think that may be more up your alley.

Thank you. I would like to suspend a speaker up as close to my ceiling in my one car garage guys, the height is only 8'. This is the pic of the area with the red arrow showing where I would like to hang only one of the speakers in the pic

and this is the speaker here:

As can be seen it is 76lbs and does not come with flyable line array options. I have put the pair up for sale and working on getting one EAW speaker like this:

which has options for flying. 2 problems I am facing, the wall has hollow bricks type and the ceiling has 60 year old beams so I don't know if I should fully trust either wall and/or ceiling to hold the 76lbs? Therefore I am looking into all possible options for this please, thanks.

From what I can tell you're just looking to hang speakers up in your garage not a line array. A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. 

Yes, sorry for my lack of proper terminology. To hang just that one full range speaker over my subwoofer which is on the floor below.
