While on the theme of questionable upgrades, I've just bought a pair of
S/H ATC SCM 19 speakers - an older pair, the same as these:

They arrived with the dust caps pushed in - both:

The seller sent them in decent boxes, but packed them solid with bubble
wrap. I think the bubble wrap just worked its way in during transit.

They work fine - but obviously I'm not happy with them like this.
And no
grilles.

I've contacted the buyer, and I'll see what he says - but I was
wondering what the thinking was on making this good.

** A sewing needle usually does the job.

Just dig the point into the depressed centre of the dome, lean the
needle
over and pull back. May need a couple of tries to get it all out.


Phil's remedy is a good one.

An alternative, is a small soft-plastic suction cup
(for example the kind used to attach a parking
permit to a car windscreen)

Gentle suction, and improvise something from whatever you find in the
house.
For instance I would use a VAX vacuum cleaner on its lowest setting,
with the bypass hole open, and a clarinet, though a kitchen funel would
do instead.
Regulate the vacuum with the hand holding the VAX to the funnel.
Or you could just suck. It needs very little force.

What you need is a self-limiting force - an initial jolt to get the
thing moving, but you don't want it to move further than the position
it's supposed to be in. I'm thinking of something like a cross between a
breast milk pump the shape of the dome and a solder sucker. Once the
dome material reaches the dome shaped breast pump bit, any further
movement has to be somewhere else. Someone on here with loudspeaker
design experience ought to be able to design the parameters of the
solder-sucker bit, but as long as it's a good fit for the dome and the
evacuation hole[s] are small enough that the suction doesn't break the
dome material, a play-it-by-ear solution ought to work.
