Hello
I am learning to use ARTA using this tutorial Quasi anechoic loudspeaker measurements Part 2 | Audio Judgement
The first difference in reality was that when using the scale amplitude after measurement - I inserted the numbers (Aport/Aspeaker)^0,5 the result was that the port volume was 10db lower than the cone volume which is not correct at all.
Is there a different method for matching the measured port FR volume and cone FR volume?
To mach the graphs I manually tweaked the numbers until the desired results appeared
The second question is why does the summed graph look like this? The green line is summed FR, red is 1 meter far field measurement, purple is near field port measurement and orange is near field cone measurement. 12" driver
Thanks
