Replacing driver screws with brass screws


There was some discussion about this on Millercarbon's thread about the Moab speakers, and I wanted to pursue the subject further without interfering with his thread.
As I stated there, I have heard about this practice for quite a few years, but never tried it because it seemed like one of those lunatic fringe ideas; and even though I actually really enjoy trying tweaks, and have found many of them effective, I just was not prepared for what this one did for the music coming out of my speakers. 
Specifically, it improved the detail in ambient trails, focus in general, complex harmonics in voices and stringed instruments, and instrumental separation. It is not subtle, and it is immediately noticeable.
So, I am curious to know how many of you out there have tried this, and what your experience has been.

brass  screws  is not audiophile approved , you have to send screws
to stereophile to make acoustic measurement  and we have to see difference .  also is very important the  screws  size . you have to drill bigger holes and use big screws. Fantastic improvement
Hello,
One of the reasons manufacturers hate to use brass screws Is they are hard to keep perfect and scratch free. They have to be hand tightened which makes it difficult to torque with a specific amount of weight. Even on an expensive speakers it is something that could cause problems. Also you probably need a revealing system to hear the difference. Last is it costs more. Maybe not a lot but it adds up. I will bet you it might only cost about $20 to try it. What’s the harm. We all spend thousands of dollars on our hobby what is $20 more. Also, sometimes people ask how did the electronic measurements look or differ. Do you know how many speaker manufacturers have a perfect measurement but the prototype speaker sounds bad. A lot! I think we should try it and post our results on this thread. Maybe we can get the screws from Ace Hardware. They carry a ton of specialized harware. If they don’t work return them. Cover the screw driver head with tape so you don’t mar them. If they do work. Good for us!
“it improved the detail in ambient trails"
I usually just smoke another joint for the best ambient trails. Yea, I find it to be one of the best tweaks.
@cal91,

'I am a Harbeth owner and I don't see how I could do that with the screws securing my drivers.'


As an Harbeth owner perhaps it might help to be a little more familiar with the Harbeth website?

Alan Shaw stated that it's no big deal as long as you're sensible and use no more pressure than is required to meet resistance. 

Basically - Don't go mad!!

If you're really struggling I can try and dig up his exact words for you.


As for brass screws, let's not even go there!

How about simply trusting the manufacturers?

The people whose livelihoods depend upon their products.

The people who have spent a lot of time and resources building loudspeakers.

I might not like a lot of loudspeakers out there, but I'm not going to pretend for one moment that I, with my severely limited resources and knowledge, could do any better.

Seriously, if anyone is considering ruining their speakers in this way, it might be wise to contact the manufacturer first if they are of any value to you.
