Adding a bit of notes from my testing, as it was at this point I really began to notice the nuance in small changes to my system. While this is not a new experience - being able to adjust my system, and not just hear fabulous sound from dealer setup, was a pure joy.
Good or bad, I was able to begin pinpointing certain strength/weakness as well. For instance, @RonP when I pulled the speakers off the walls 4-5 ft, it added a great amount of depth and dimension of the soundstage! However, I lost most of my real deep bass (below 30Hz).
I didn’t worry too much as I just marked this spot and noted a 2nd spot to push back near the wall for when I played some organ tracks or similar ultra bass options.
However, during this period, I noticed I was gaining some listening fatigue when playing an hour or more; I also noticed a slight glare on many songs. Through some dialogue with the original designer of the speaker, he noted that what I was more than likely noticing was not only a drop below 30 hz, but also a drop in the lower mid bass all the way down, causing the speaker to sound slightly “bright.”
That was news to me, but to validate I measured and, sure enough, I lost anywhere from a 1-3 db from 160 Hz down to 26 Hz and then it took a nosedive below 26 Hz when I had it 51” off the wall - compared to when I couple it (2” or less) to the wall.
So I’m left with 2 different sounds - the awesome soundstage, but a slightly bright option when pulled off the wall; or a better neutral sound with proper bass, but decreased soundstage when coupled as the designer intended.
It was at this point in the summer, I was off to research some speakers to compare…
