View Full Version : Tannoy dust caps
I know it's a fairly common practice to remove the dust caps or not bother installing them after a recone and was wondering where they all go?
I'm after a pair of the 4.5 inch nylon mesh ones from the K/DU models(3128/3828 etc).
The cloth HPD ones are still available from that man on eBay but scrap or mint would do....

When I sold my K3808 project, put them in the cabs for the buyer to use at later point.. Think others just throw them out..
There must be numerous types available on the web, I would go for the coarsest mech you can find, and nylon is likely to attenuate HF less than cloth/fibre types.
Genuine pair now sorted, thanks.

I have heard the opinion that without dust caps you need to blow off compressed air every year to avoid accumulation of dust. Because dust can become a conductor and cause problems.

Not so. Dust will not build up in the voicecoil gap as the oscillations of the cone produce a pumping, bellows like effect blowing air back and forth through the coil area.
Dust accumulating on the cone surface can be brushed off carefully with a soft paintbrush or makeup brush. Use of compressed air is not a good idea.
