Thanks for this. It is amazing how hard it can be to accurately measure anything. Interesting stuff, not just for those with a passion for speaker measurement...
Explanations in this video are sometimes way to quick to understand , especially for non-english followers! Reducing video speed helps but converting artefacts (sounds like hard clipping) disturbes sound , quite annoying!
Thanks for this video, this channel (Alpha Sound) have really good stuff on YouTube. Their video on bass and ports (link) massively improved my understanding of my topic, though it did take a few times to fully understand it
