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
