So, you get a pair of loudspeakers and a room with comfortable foe you reflection pattern. You set up left loudspeaker (left for you) where I need to be. I always suggest starting from left loudspeaker as it cares the fist violins, sopranos of choruses and generally in western culture is associated with HF lead. You take RTA or TEF pulse analyzer and perfects align each channel of the loudspeaker to your listening position. Then you take a right loudspeaker and do the same.  Rgs, Romy the Cat

They the fun begins. You need to align the right and left loudspeakers to each other in respect to this position in the room. We are not taking here about arrival time and it will be skewed and hardly measurable as we will not be able to subtract the modulations from reflections. So you take pulse analyzer away and using just TRA we are trying to setup R and L loudspeakers to have max amplitude of each other impact.  Here is where you deal with true DPoLS. Rgs, Romy the Cat

Stirling Trayle and I exchange a few you messages. I sent him a link to DPoLS translation and he immediately identified some weaknesses of the article, very impressive. I find that what he does is exceptionally interesting and uniquely rare. I have a reputation do not patronize on recommend any business or services in audio but in this case I would like to make exception and provide my very strong recommendation to use Stirling Trayle while she is still able to operate. As I understand he is in his 60s and after he will be gone this knowledge, from epistemological perspective will be lost. I did suggest him to write a book, I do not think he will, and it is very unfortunate.

Hi - take a look, may answer your questions about knowledge transfer of the process, but the experience will be missed without his personal notes. https://www.audioaficionado.org/showthread.php?t=46634 I also use REW to capture room acoustics.  Then consider applying acoustic treatments to address. The "art" is where and what to apply - diffuser, absorption, thickness and how much.
