Thanks a bunch for explaining. It makes more sense now.
I found some photos of a pair of IRS Vs.
From what I've read you can get them for about 30% of the original $80,000 they cost back in the 80ies. I'm still checking the yard sales!

Most of that money is spent on cosmetics. Sure are pretty tho..
Physics, Its actually an easy concept, its a true line-array system. Usually all same size full range speakers in a straight line. Anytime you put 2 of the same speaker with same signals next to each other, between each speaker you gain 3-6db of volume the amp is not producing itself. Keep in mind 3db is the doubling of volume.
8 speakers in a row, wired in series-parallel, you will gain up to 36db of volume the amp is not working to produce, physics.
If you get to liking having a mixer at home, and wwnt more inout channels look at Mackie small mixers.
Driveling off the map,…Todays concerts when you look up at the speakers, same thing. Most call them line-arrays, but they are really variable-arrays because we can bend the stack like a banana.
EAW makes a true line-array, we used for Tom Petty. These are top shelf of top shelf. Using computerized digital phasing we can actually steer the sound around the room without pointing the speakers that direction. Insanely expensive at $28k per cabinet , insanely heavy as hell, we usually used 10-12 speakers per array, 6-8 arrays. Pretty crazy to hear the sound move around the room. Add stereo mixing and you kinda end up with 3D sound image.If they were around during Pink Floyd it would have been epic.
All sound is 100% physics. These are the calculations we are doing.
Lighting and video projectors kinda work the same way. Before video walls using a screen we use two projectors, both images layered on top of each other on a screen, its twice as brilliant.
The biggest screen I did was 400’ wide, using 16 high-end projectors and video mapping to make a 400’ wide video look like a 4k TV. If you use IMAX cams its stunning.
