Dented Dust Caps?

[ontime1269]

I've searched the net to find out if dented dust caps affect speaker sound and can't find out a definitive answer. Some say yes, some say no. Some say dented dust caps affect midrange frequencies but not subwoofer frequencies. Does anybody know the definitive answer? Thanks.

It would have to effect dispersion to some degree but so expensive drivers do have angles and what not in the cones dust caps so should not be tooooo big a deal. Looks bad though if you can see it.

Actually had an accident with one of my SLAs and we popped it back out after putting a tiny hole in it. Hard to tell now.

I've pulled dents out of dustcaps with a vacuum cleaner hose. Probably not the best idea, but it worked and I haven't screwed up any drivers doing it. Try it at your own risk.

scotch tape on it and pull it up

I would say it depends on the dust caps. Some dust caps are more of a thin mesh that contribute nothing to sound. I don't think a dent will matter much with those.

A paper dust cap will be more important to reproducing highs, and even more so an aluminium one.

The big issue, however, is what the dented dust caps do when you push bass through the driver. A dented aluminium dust cap will very likely rattle since the structural integrity relies on a spherical shape. That rattle can be clearly heard. Been there...

I tried using the vacumm cleaner but there just wasn't enough suction to pull it up. I tried using some duct tape and some gaffing tape but the adhesive wasn't strong enough on either of them. I'm about to head to Lowe's to try to find some tape with stronger adhesive. Hopefully it works.

But if the dented dust caps don't affect sound in any way, I'll just leave them be as they won't be seen. By the way, the speakers are S2010's. Do you think their performance will be affected by the dented dust caps?

Take a needle or a fine pin and bend the tip into a little hook/L shape.

Poke it into the middle of your dent and use the hook/L to pull the dent out.

If you're worried about the hole, put some white glue on it.


I've done this many times after trying vacuum and tape first.

Yeah, I tried the tape and it didn't work either. I was trying to avoid poking a hole but I might have to. I wish I could test the speakers to see if there is a difference in the sound with a dented cap versus an undented. No built cabs yet, oh well.

How many times have I told you young man? Bad things happen to your speakers when you play with them before they are married to a cabinet!

In addition to the vacuum, blow into the pole vent at the same time. I have had to do this when the vacuum wasn't strong enough.
