I am French and I do not know how to write in English, so I use an automatic translation and I hope my question will be quite understandable for you.
I bought R80 monitors and am currently testing the monitors' placement distance from the rear wall.
For this I consulted the guide "Studio Monitor Placement" here: https://www.presonus.com/learn/technical-articles/studio-monitor-placement
It says this:
"Make sure that your speakers can be placed away from walls. Eight to twelve inches will be adequate to prevent sound waves from hitting the wall and reflecting back to you, causing phase cancellation and other potentially harmful acoustic interactions..."
What I would like to know is how to take the measurement, is it from the back of the monitors or is it from the front?
In advance thank you very much for your answers.
