Comparing & plotting spinoramas

[radix]

I am trying to compare the F228be from ASR with the R11 from spakerdata2034. I know that Amir posts the raw data, is it also available for the R11? Also, what software does one use to make those plots?

Eyeballing it, it looks like the main difference in SPL is the F228be is a bit better < 30 Hz, and starts climbing the linear rolloff maybe a bit sooner than the R11 (say 35 Hz vs 40 Hz). Perhaps the F228be is a little flatter from 100 - 10kHz?

I didn't find directivity data for the R11. Can someone point me to that?

Thank you

@napilopez has tools to scan the kef whitepaper for the r series and compare to spins provided by amir, erin or himself
