<10% THD <50hz is considered good usually I think? But what is acceptable? What is bad etc etc? And is 1% THD a lot better than 9% THD?
You mean something like this?:An exceptional THD figure would be something like 100db @ 20hz with 8%THD
You mean something like this?:

It's my setup at home (PB13-ultra in 15Hz tune ).
So would say a 5% reduction in THD at 30hz from 9% to 4% say at 100db make a lot of improvement?
Or because the THD is <10% this reduction does not matter
