Hi. Thinking to try putting my subs just behind the sofa to compare this to my current setup. In the this new configuration from my ear level the sub will not be visible due to the sofa back. Will YPAO calculate the distance as the one from the sub to the ceiling and back to my LP? In this case i will lose the whole point of nearfield placement. The question not just about YPAO but in general about getting higher max spl.
