Since you admit you don't know what you are doing-exactly what "MATH" are you going to use to figure out how one system compares to another?
How do you know what parts/models to use?
I a line array from brand A won't fit-then what makes you think a line array from brand B will fit? I guess it is part of the "math"
BTW-Since money is an issue you are going about it TOTALLY WRONG!!!!!!!!!!!!!!
If you rent a whole system from somebody who will come set it up-tune it-run it and tear it down, it will be WAAAAYYYYYY cheaper than renting individual pieces. And if you rent it yourself-how do you know how to put it together-tune it etc?
There is generally no cost to go talk to a REAL sound company and at least get an idea of what it would cost for them to do the gig.
All it costs you is a little bit your time-which you seem to have plenty of by trying to come up with ideas that either won't work or don't make sense.
The Math i am doing is nothing more then finding out how much the PA will cost the numbers i am using are
x24 D&B Audiotechnik J-12 Element's
x10 D&B Audiotechnik J-8 Front Fill's
x24 D&B Audiotechnik J-Sub-woofers
x4 D&B Audiotechnik M2 Monitor's
x4 D&B Audiotechnik Amp Rack (Array only)
x8 D&B Audiotechnik Amp Rack (Subs only)
x2 D&B Audiotechnik Amp Rack (Front Fill)
x1 D&B Audiotechnik Amp Rack (Monitors)
I would hire a sound engineer to tune the system. In the last thread pretty much everyone said it was going to cost at least 10k which is the number i am at right now without front fills and a mixer and an engineer, so more or less its the same cost and im not comparing the systems at all I am simply just filling out numbers of what i think i will need based on what i've been told by you guys and what i've read. looking at it now i may have too many subs but you guys say its pretty normal to have lots of subs for edm.
