I would be surprised if anyone could do a true blind listening test (having someone else take the grills on and off) and actually be able to correctly state whether they were on or off more than 50% of the time.
I appreciate this forum because it maintains a factual stance regarding many esoteric (and expensive) tweaks, etc.
Are there any studies of a few speakers with and without grills to establish that they are truly acoustically transparent in the high frequencies. I certainly do perceive a difference on some of my speakers (not all). However, I am human and this could well be more of a psychological phenomenon than an acoustical one. Certainly instruments could measure this better than
any person could hear it.
It would be great if someone knows of some testing to determine this.
Like I said I cannot notice the difference on every speaker I have, but I cannot understand how grill cloth could be completely transparent. I would expect that
all grill cloth would show a
measurable effect, but that I can only perceive where the difference is
audible to me.
