Sure, you can have. One of the tests was with a cabinet on one side using a standard MDF panel and the other one with the same thickness panels but done with constrained layer damping (two layers, damping in the middle). The cabinet was a smaller 2-way, so no other internal bracing was used.
But this is the problem here at ASR: Whatever I say, somebody says something like "I don't feel like" - like you did above. On one hand, people are screaming for blind A/B test, but never did anything themselves to prove their own theory.
This is nothing against you.....but think about it and read some of the comments to understand why I'm turning around and walking away.
I have no problem discussing with people who have worked on the same things as we did here. It's only difficult to discuss with people who are biased in one direction and turn whatever argument does not fit into their world down with "I don't believe, show me the AB test".
well to some extreme I would say just like flat earthers, when things are biased it goes to extremes, but personally, I have no insult, just the explaination didn't get over my logic, say for the highlighted part, I am sure that would sound different, as damping was done, and sometimes even say, smooth/lined port could sound different as it can cancel out the port chuff. but also, in those case which was in my very early days of some noob DIY crap, the measurement did become different after some linings are added. I am not saying the material or weight of speaker cabinets would make no difference, what I am not getting is that sound is just physics, air vibrates and pressure waves reaching our ear drums and we hear the sound (and the mic measure it also), so if anything was audibly changed, it have to be measurable, maybe not in on axis plot, but maybe some resonance messy but tiny peaks and dips, maybe off axis gets messy.
Or even say, if the design excelled in on axis FR and have perfect directivity, and the excelled resonance is then pulled down aggressively by EQ, it could show up in weird distortion spike, or RT60 plot. Or another extreme, assuming one cabinet have zero "through the walls" sound emitting out, and another one have excessive through the wall sound, it have to have different directivity plot, as one only beams forward and the one with no blockage walls would become omnidirectional extra sound emitting out,
What I don't get/ was curious was not that same design, same thickness, just different side panel construction material would sound different, but that it will sound different AND not being measurable. I know that in the early days of measurement, ppl only measure on axis FR, so with directivity error messing up with final sound, it is more often than not on axis flat speakers sound like crap. but nowadays the plots done in SPINs are so complicated it have to affect one plot or another for it to be audible.
Please also understand here quite some members have had enough of some really huge snake oil designer BS, say the various directional cables.... and in various tests/auditions I've had the pleasure to join, I have yet to experience anything not measurable but audible difference, personal difference is another thing, Harman research is only a general trend of preference, which can differ a lot from one to another person, but more often than not what I personally found was that the mic is 100% of the time more sensitive to our ears, I've only experienced differences measurable but not audible but not vice versa
