How to clean drivers
« on: 10 Oct 2021, 12:17 am »
Yet more questions for the crowd as I get my kit ready.

Some of the drivers have a white substance on the cones (see photo). This raises a few questions.

1 - any idea what this is and if it is an issue?
2 - if it is purely cosmetic, any safe suggestions on cleaning? A wet cloth got another driver with this cleaner, but it still looks a little discolored. Also, the one in the photo is closer to the dust cap, and I am worried I will not be able to clean it effectively near the dust cap unless I use something thin with a solvent, but I fear a solvent will damage the cone.

Any advice?

I use a make up brush that one of the daughters didn't need.  It's probably over 4 inch handle and almost 2 inch of very soft bristle.   It's also about as big as my thumb.  Great for keyboards and louvers, knows etc.

This is a doped cone?
I dont know this driver but IMO in my past experience clean doped cones/suspensions or silk domes by rubbing or brushing is a dangerous job as they stick on everything.

Is it an optical illusion or does your phase plug have a dent in it? If it’s dented, is it possible the cone has damage as well? It’s hard to tell on the reduced resolution photos on here what exactly is going on.

I just got most of the parts for my nxtremes today as well - and they also have some kind of white powder or residue on the cones. I think I'll be able to clean them off just with a microfiber cloth or something but haven't tried it yet.

Optical illusion. The cap is fine, just that weird stuff on there.

The brushes are a good idea generally, but this seems to be more adhered...

I wouldn't ever use any solvent or cleaner on the cone of any speaker.  Especially these that look like they have a coating on them.  If it doesn't come off with a brush, I use paint brushes, it was meant to be there.

Got it. Like Letitroll98 I’d not recommend a solvent as it would be hard to know if it would dissolve the treatment on the paper cone. Hopefully you can get it dislodged!

You might want to try a foam tipped swab and a can of compressed air. The "great satan of retail" sells both.

Similar to the previous post, what about a Q-tip cotton swab, possibly dampened with just a drop or so of water?

A good idea unles the cone has a sticky surface, regular q-tips can shed fibers. An example of foam tips.

Don’t use rubbing alcohol. Learned my lesson.  That’s the only gripe I have with my Nx-Treme’s is all the imperfections on the mids and woofers.

I took the brush advice and it worked pretty well. There is still a discoloration on the cones, but I guess I need to live with that.

Thanks all!
