Replacing driver screws with brass screws

So what you're saying, to even talk about brass screws takes brass balls. The man's a poet, didn't know it. As Will Shakespeare once said, This s**t writes itself!"

Well, there’s three choices: try it, talk about it, or just forget about it. All valid.

Ok, "My turn"!
And please feel free to look this up!
There are several reasons replacing the screws with "Brass" will change the sound of your system. But it needs to be of the "Cast" variety.
There is actually, a single "published" study by a well known and very well regarded "Ivy League" university as well as many others currently, "Un-published" and still, um classified. "I know of at least fifteen of these".
The un-classified study is not hard to find online. Just ask the right question of your browser!
And ALL of them were commissioned by the federal government with most but not all paid for by military research entities. Also they were all offered, and completed within the same 12 year period. They were to study and classify all known alloys with the goal of ascertaining the effects on electromagnetic fields when different alloys are applied to said fields. They found some odd things. One of which is that "Cast Brass" works as a mid-range frequency, resonance and free harmonic filter.
It's been awhile but I believe the range was roughly 1.4Khz- to a little over 5Khz. The brass could also be used as a type of particle boundary. They can also help stabilize a field if used in a certain fashion. And since the voice coil works how it does this applies. No snake oil here.
I use cast brass machined screws to secure the transducers in certain bass columns I build with "Storm nuts", "I think that what some call them".
On the inside of the cabinet which are stainless steel with the (teeth), biting into the cabinets wood. I use fairly large screws and they are torqued to spec. so that the threads are not damaged.
If anyone really wants but cannot find that study I talked about above? And would like more info. I do have it here in hard-cover, book form. "Somewhere". I would just have to dig it out.

Color me impressed!

My question about wooden screws is very real. It is just another material. If brass, and we have no idea what composition we are even talking about, is allegedly making a difference then any material could be making a difference.

Same goes for "brass on the speaker". Different enclosure materials, many physical variables (location, number of screws, size of the screw, etc.). It is a nice start to think "brass", but it becomes a little suspicious when with all the possibilities "brass" is the answer and any development of that question becomes "not serious".

Is it maybe zinc in brass we are really looking for? Maybe copper? Or maybe zelkova?

Also, there is a mention of "tightened to spec" earlier. Do manufacturers publish those specifications?
