PA speaker

Hello Everybody !

I am new to speakers, however I have this project that I would like to realize, I was wondering if you could help me figure out what I would need to make it real

I want to build this speaker, it will be a big one, the question that I have would be where I should put the speakers, how many I would need, so it gives a equal spread of sound, however I was thinking if I could do it with two big PA speakers on each side, however would I need other small speakers as well ?

It would be great if I could find out what components I should buy, to make this work.

I am attaching a picture!

Thank you for your Time!

1 large driver per side will not cover an acceptable frequency range. It would seem from your diagram that you want a very large sub and then a smaller speaker on top. If you wish to keep it simple, you could do a large sub, and then a reflex mid top. The dimensions you are giving won't fit through all doors. I try not to make speakers wider than 636 on at least one plane so that they will fit through single doors. Also, a very large box like that may get you lower frequencies, but they will likely reduce your potential SPL. Perhaps a dual 18 reflex like a Gsub would satisfy? Bonus would be that stacked sideways it would put the mid top near head height. Then for a mid top a simple reflex 10 or 12 and 1. If you want to do horn loaded speakers you may need more bands and you will need more processing for timing alignment.

Thanks very much for your response and advices ! I will look into it and keep you posted of the result !
