There are a lot of available data on PA speakers. Companies are used to share data mostly because buyers need them to compute how many speakers and which ones they need to light up a stadium. I discovered recently that a lot of companies published data in CFL and GLL format. GLL has a free viewer and you can export data. So that's what I did: I used windows automation to automate the extraction of data from the GLL files provides by JBL, QSC, Neumann, Genelec, Meyer Sound you name it.

I am transforming a lots of GLL files to something we are used to see. Thanks to @test1223 for this idea. That's not a fully automated process and results needs to be manually checked.
Concordance with speakers measured by @amirm is usually great but I also see a lot of very smoothed data.
Some examples below:
ASR v.s. Genelec gll data
ASR v.s. Neumann gll data
Things can diverge a lot more
Here are a few PA speakers examples:
Meyer Sound Ultra X20
Meyer Sound Lina
Interesting speaker, please not the DI is almost constant and that freq response can be EQed. They are for line arrays.
QSC K8.2 (data is very smoothed)
JBL 9310 (data is very smoothed)
Building a ranking system for PA speakers will be difficult since they don't necessary have the same domain of application.
Classical dipole or tri-ways, yes they match the directivity of home speakers.
Line arrays are different beasts and you cannot really compare them to something else.
Surround are also different.
Most of the PA speakers are also not covering the whole frequency range and subwoofers are
always added to the mix.
Some fun discoveries:
JBL C211
Interesting spike and very flat DI above 2k.
JBL C222
Freq response looks crap but look at the DI and the PIR:
Not bad at all.
Conclusion so far
- Lots of data out there some of it of high quality (Meyer Sound, Neumann, some of the Genelec), medium quality (JBL), low quality (QSC). I have found hundreds of gll files in a few Google searches.
- PA speakers have different DI (no surprise)
- Some PA speakers are excellent (Meyer Sound Ultra X20, X22, X23, X40) for example.
- You need to read the footprint in each gll file (smoothing, precision, low freq validity, which angles are available...)
