I was re-finishing the cabinets of my Klipsch Heresy speakers today and had the front grills off for the first time in a long time. They are quite dusty inside, including on the surface of the woofer. I have never cleaned a cone before. Or, it's been a very long time and I didn't know what I was doing when and if I did.

What do people recommend I use/do to clean them? Slightly damp cloth, feather duster, don't touch them?

By the way, I sanded the cabinets to 220 grit with garnet sandpaper and will be giving them 3 coats of polymerized pure linseed oil and then a coat of beeswax. The first coat looks fantastic already.

I use a soft paint brush and gently go around. This can take a little time. Removing the woof after an initial dusting makes it easier and safer for finishing.

+1 Paint brushes will gently remove the dirt, will not snag anything and will not leave any residue.

A paint brush just smears the dust, a swiffer attracts the dust away.

With the accordion style suspension you can use a vacuum, they are tough enough to take it.

No one said your process is wrong, but there may be more than dust.

The question is

No debate, just stating what I use as you did, some ways may work better than others, the poster will have to decide the one they prefer...

Okay great! Thank you. I will give both methods a try and experiment a bit.

I used the swifer duster that has more wax on the cloth to take up more dust. Also use a silicon roller for the other edges if its really bad. Then I used a can of air and blow from an angle away from the center to clean it. I have also read where using that goop putty for cones that are made of plastic or other shiny material works well. Good luck. I have Heresys also .

Awesome thanks. Can I ask what amp you use, or have used, to power your Heresys?

Some good ideas here,

Just think it through - you'll figure it out.

Personally, I usually (as others stated) get a soft bristle paint brush and use low power compressed air. Like a can of air, I set my air-compressor equally as low and brush while giving some light blown air at the same time to lift the dust.

Heresy's don't have doped surrounds (or at least not the sticky type) pending the year manufacturered. I've had 3 pairs over the years - so, the edges do not typically attract much dust; however, if they have - I will first try again as above & (if need be), I will (literally) pick the crap off the surrounds with a pair of tweezers to not damage the surround. Usually, the wooden edge (around the bass driver) is what attracts dust. It is usually NOT a smooth surface, making it harder to remove (read below where I address this)

You may be able to (as another posted) get a vacuum in there - just be smart about it. You don't want some monster vac creating too much suction and distorting the surrounds or pulling the speaker unnecessarily to the left or the right as you do so. Remember, old things come apart. Surrounds, speaker spiders, etc. Be careful. You may want, if you go this route, to attach a very soft bristle end to the vacuum - controlling the distance to the speaker and helping loosen the debris if necessary.

IF the surrounds are sticky, they have been probably redoped by a previous owner. I had a pair of Altec that were redoped by previous owner, if took me about an hour per driver with tweezers to remove the large hairs and such; however, it was worth it as most anything else will add dust to the equation.

I also agree that if you are going to refinish the cabinets, removing the driver carefully is worth it as your hard work will only be lost to the dust created in sanding. Remember, the fronts of the Heresy are a flat black. Sometimes, not so smooth, making rubbing a damp cloth on the flat black a no-no as it will generally leave bits of fabric on it or paper (if you are using a paper towel). Better to use a brush here and vacuum to lift the dust - even a damp cloth at times with affect the finish on the flat black fronts, test an area before adding damp to this area.

Take you time and enjoy!

who is the manufacturer of the polymerized pure linseed oil and the product name?
If vaccuum be real careful to use strength adjustments-as weak as possible enough to draw the dust off a fine brush will dislodge and draw the dust away from ie-accordion and other fragile areas

It's called Tried and True Danish Oil and is sold by Lee Valley tools. It's top notch and I've used it for years on many different projects. It's a beautiful product that is forgiving and a joy to work with.
