I plan to first try uniformly tightening the stock screws using the Wheeler Fat Wrench as demonstrated in the video. If that proves useful, then I'm going to look into the brass screws. |
Brass is the metal of music.
Theaudiotweak (Threads | Answers) Maybe you could sell t-shirts! |
I'm going to try a couple of SP-004 under my Sonata III loudspeakers. What's the best technique for placing them? Seems that three people are likely necessary: two to lift, and one to place the stands.
BTW, I'm not an ad-man. |

I bought a Wheeler online from an outdoor sporting goods supplier. For some reason, I believe the equal torque on all the screws is as important as the brass screws. The screws are certainly the least expensive part of the overall tweak.
Of course, now you absolutely MUST have the screws cryo treated.
...just kidding. |
It does say 10 ft.-lbs on the ad I recently saw. Rick was using one in the VD video, and he mentioned it goes down to 6 lbs. He uses it to adjust gun stocks on his high end target guns.
Guess I'll find out when I receive the wrench. If 10 ft-lbs is the lowest setting, then 10 ft-lbs it shall be. At least all the screws will be equally torqued. |
Hope I ordered the right one! |
Perfect stocking stuffer for Uncle Jed Clampett. |

Sherod, you sure procured a torque driver lickety split! |

I just fashioned another tweak...a knock-off of felt tweeter surrounds presently being sold.
$23 worth of high density felt from McMaster dot com, an an arch punch purchased on E-Bay. Fastened to the speakers with TopStick toupe tape (my wife is a professional make-up artist, and TopStick is part of her kit). You can find it in drug stores, I think.
I have a 12"x7" piece of felt remaining for purchase if anyone is interested in making their own tweeter tweaks. |
I haven't listened critically,yet. However, I do notice a slightly less fatiguing sound, and I changed the toe-in of my speakers a little (toe-ed them in more). They are easily removed, and the TopStick used to adhere them will not leave a residue, so there's no penalty in trying them.
The Absolute Sound just gave the professional version of these tweeter surrounds an award, which you may have seen. |
That makes sense. When I replaced drivers on my Castle Acoustics speakers, the replacement drivers came with new foam gaskets. I suspect over tightening would eliminate the benefit of the gasket.
The VD video makes mention of not using too much torque on the screws. |
This thread is about to take a detour... |
Hey, it's your thread...
Buckle up!
:) |
I was surprised that with all my strength I was unable to tighten any of the screws on six woofers that I checked.
Albertporter (System | Threads | Answers) I did not take away from the VD video that getting the screws the tightest thay can be is necessarily the goal. I was under the impression that somewhat looser is better (not loose, but looser than cranked all the way until they cannot be tightened any further), and that all the screws be equally torqued. |
Well, after purchasing a Wheeler Fat Wrench, which is a real piece of junk...the hex adapter doesn't fit properly so the thing wobbles while you're tightening the screws...
...and after being unable to find brass bolts to fit my Dynaudio drivers...
...and after being unable to find a 3mm hex driver attachment for the Fat Wrench...
...I'm abandoning this tweak.
I was able to uniformly tighten 48 out of 52 screws on my speakers (the other four had slightly stripped heads), and I didn't notice any difference afterward.
Moving on! |
Mcmaster is a great resource.
Are your screws hex, slotted or philips heads? The screws that hold the Silverline's driver assemblies together (as opposed to the screws that secure the entire driver to the baffle), have flat sided, cylindrical, hex driver heads.
If yours are the same size as mine (I don't know my size...maybe send me one of yours as a sample?), I might buy some. |
Mine are metric.
I did drive to a local fastener supply house a few weeks ago...one of the largest in LA...and they sent me away in a hurry. They didn't carry metric machine screws in brass.
Frankly, I have little interest in doing the research to determine their size. |
They arrived damaged, so I was unable to try them. |
