Aluminum dust caps?

Hi,

Was fooling around trying to fix voice coil rub & I ended up mangling one of the dust caps... It's aluminum-type, @1-1/2", the only replacement I can find are 4" JBL's, if I cut these down (carefully) will they work ok? Is there somewhere that might sell smaller sized aluminum dust caps that I'm unaware of?... Right now I'm just using the remains of the dust cap taped together... Any thoughts?

Thanks! T.

You might try Weber speakers, they make guitar speakers with aluminum dust caps.
While I doubt they would sell you any, they could probably tell you where you could purchase them?

Good luck!

Ooh yeah, I took a look at that "beer can" DIY dust cap thread... the aluminum on a can bottom does seem a bit sturdier & heavier than the caps I have, maybe I'll try it & see...

Thanks, T.
 
All kidding aside, Pillsbury cinnamon rolls come with icing tubs that have very rigid 2.25" aluminum caps which are slightly beveled at the edge. These may also be a candidate for substitution.
 
Mmmmmmm....Cinnamon Rolls.....

You only mention the diameter. As you can see from the collection I have in my photo, the diameter is just one aluminum dust cap characteristic. Some come with down outer edges so their ID can be directly coupled to the OD of voice coil formers. Some have an angle up lip around the outer edge to provide a glue surface for attaching the caps to cone bodies.

The gauge of the aluminum used in dust caps is thinner and lighter than aluminum used for such things as soda cans. Using any material with more mass would completely defeat the purpose of using aluminum in the first place.
 
I suppose it would be fairly easy to make a potential substitute, and compare mounting, mass and other characteristics against the original.
