Dust removal - Tweeter SBL

Hi-Fi Corner
1

Hi
when I had moved the upper front grill from one of my SBLs I (again) recognized that there is some dust laying on the cone of the tweeter.
Must been very long and from a time, where I had no grills on.
Nothing bothers me during listening to the music.

But is there any chance to remove the dust - looks like it sticks there.
I have not tried anything yet as I do not want to come near the little cone.
A small and smooth brush from lens cleaning? No idea?

I can also leave it as it is. With grill on it is a no see :slight_smile:

Thanks for any advice

edit: found in article from dynaudio (sorry in German). It says - hands off! The dust you can not blow of is no problem for the sound. Anything else is too dangerous to manage!
OK - I have done the right thing :O)

Also Foul s suggestion with dishwashing liquid in a forumā€¦ this is not my preferred option :slight_smile:

Iā€™ve never needed to do this but if I did Iā€™d think about a puffer brush of the type you might use on a camera.

A vacuum cleaner with a long horse-hair-brush attachment on very low power, with some dexterity applied.

I have thought about the optionsā€¦ none is valid for my gut feeling.
Will go for a very soft brush and try it on an older speaker not in use.
Only if I have a good option, I should post a pic.
I know me - what if someone will mention that it is too much dust ā€¦
No audible for me - maybe the fine dusty hairs give the good analogue sound :slight_smile:

The Scan-Speak tweeters are as tough as old boots. I wouldnā€™t worry so much. Itā€™s not as if they have ferrous-fluid or aluminium domes.

That is good news. Will think about giving it a smooth brush

8

I think a ā€œswifferā€ dusting kit would work

Not a good idea

10

Itā€™s not an idea, from personal experience. What was you thinking?

11

Yes I would not take a Hoover to fragile transducers. Just my opinion of course

12

Do you have ā€˜actualā€™ experience of the ā€˜transducersā€™ that iā€™m on about?

13

No but do you :wink:
I would ask Scanspeak first if that was a good idea instead of relying on a suggestion from someone on this forum

14

Yes i do. Many years, of experience. BOOM!:wink:

15

Good for you Stephen. I would still ask scanspeak and not a builder or brick layer double BOOM

16

Cheers mate. Ok. Good for you.:slightly_smiling_face:

17

Sorry I donā€™t want to appear rude. I have a lot of respect for good builders. Just that I would bounce a question off scanspeak to be on the safe side.
All the best

Iā€™m going from my own experience. Not what iā€™m led to believe. Just trying to share my outcome.:sunglasses:

19

Fine, but some transducers are quite sensitive to forces that are exerted by a hoover.
Donā€™t try this at home children :rofl:

Yes. But not ScansSpeak SBL ones. It will not bother them. They wonā€™t go BOOM.
