Small dents in my speaker

Can't see the dents from here?

 

I guess you are referring to the dust cap, i.e. the domed centre? The cone itself is not usually prone to dents, but tearing. If it is the dust cap, you can usually press it back to shape, or use a vacuum cleaner as a suction tool, or replace the dust cap altogether.

 

+1 A picture is worth a thousand words.

 

That's a weird speaker injury. Do you mind telling us the story there? Shouldn't have an effect on sound unless it opens up a hole, though.

 

They don't "look" like they will cause any misalignment and I would leave them be. I also wonder how they got there?
Might want to pull that speaker so you can look for something behind causing it?

 

+1.

Definately looks like something caused it from inside.

 

Looks like a kid was enjoying himself with a pen or pencil.

 

This^^

Whenever something defies logical explanation, I suspect kids.

Hint: Teenagers most certainly qualify as kids....perhaps even more so than younger children.

 

Weird thing is that the dents appear to be convex. So they must have been made from the back. Very strange.

 

Maybe something loose inside the cabinet hitting the back of the speaker when you're moving it? Screw or bolt perhaps but I would think anything metal would get stuck to the speaker magnet.

 

Have you pulled the grille and speaker to see if there is anything loose in the cab?

 

Hard to see on the phone but if the dents are pushed outward, there is almost certainly something loose inside the cab. Possibly a T-nut fell loose from a speaker mounting bolt?

 

Not wanting to alarm the OP, but my experience with aluminum dust caps is that dents and crinkles in aluminum can and will lead to tears.

 

Indeed they do - it's called fatigue points.

 

You may have a screw or bolt flopping around inside or someone put something in one of the ports and that is bouncing around inside and hit the aluminum on the inside.Move thecab in all positions and see if you hear anything bouncing around.If not it may already be attached to one of the magnets so you may need to remove one at a time to see if that is the problem?
