Does the first reflection point actually matter??


Hello my friends,

So please read the whole post before commenting. The question is nuanced.

First, as you probably know I’m a huge fan of the well treated room, and a fan boy of GIK acoustics as a result, so what I am _not_ arguing is against proper room treatment. I remember many years ago, perhaps in Audio magazine (dating myself?) the concept of treating the first reflection points came up, and it seems really logical, and quickly adopted. Mirrors, flashlights and lasers and paying the neighbor’s kid (because we don’t have real friends) to come and hold them while marking the wall became common.

However!! In my experience, I have not actually been able to tell the difference between panels on and off that first reflection point. Of course, I can hear the difference between panels and not, but after all these years, I want to ask if any of you personally know that the first reflection point really matters more than other similar locations. Were we scammed? By knowing I mean, did you experiment? Did you find it the night and day difference that was uttered, or was it a subtle thing, and if those panels were moved 6" off, would you hear it?


Best,


Erik

Okay now you are questioning the holy grail. 1st reflection points.
I built 12each of  2' x 4' x 2" Owens Corning 703 absorbing panels.

In a room of 15' x 18' open to other rooms I deployed 2 panels on the ceiling, 2 behind the speakers, 2 for early reflections and 2 behind the listeners. Floor is carpeted.

The difference was so profound I nearly cried.

Now your post makes me question which panels are the most critical.
