#1 Dust cover been crushed by inquisitive 2 year old.

Post by Andrew »

Does anyone have any advice on how to pull out the damage done by a two year old's finger on the dust cover of the pole piece on an Alpair driver? Not mine, I may add two year old or the driver..

Suck on a straw and create a vacuum was my initial thought.

Use the hoover pipe ?

My Dyson has a slide on the tool holder to decrease the amount of "suck" so one could try it on low suck first.

No euphemism intended. :)

The audio forums are littered with this sort of discussion !
Do you have any double-sided tape ?
You could experiment with increasing amounts of contact patch ; start small to be on the safe side.

My grandson has produced this problem for me recently on more than one occasion. Certainly on my Audax units with thin plastic dust covers, suction is the answer although I would steer away from using a vacuum cleaner even if the amount of suction is variable. What worked for me was a stainless steel tubular egg cup which had different circumferences at each end. Coincidentally the fat end fitted exactly the total area of the bass driver cap and the thin end fitted exactly the total area of the midrange driver cap. Fit the appropriate end over the impressed cap, apply your mouth to the other end and make a short, sharp but shallow suck. On all occasions, my dust caps popped back without any lasting damage (much to my relief).

Failing that, you could spike through them with a bent needle and pull them gently out and seal the hole afterwards or carefully remove them with a scalpel, reshape and then glue back into place.

Certainly it is a worry should replacement drive units be the only other option. My bass drivers are now well over £200 each!

Hope that helps.

Velcro. Thats the answer.

Glue one piece to the main wall in whatever room your relatives and their young children being 'received' in.

Glue the other piece to the backs of any visiting children.

Grasp child, lift, then force gently onto Velcro taped on the wall. They'll stay there until your guests are ready to leave.

Saves a fortune in speaker drivers.

HTH, :-)

Perhaps one of these for the car park at the next meeting? I think the colours would suit too.

Small bit of blue tac and very gently ease the dent back out with a dabbing motion, for heaven sake don't use a vacuum cleaner! :shock:

IIRC, MA drivers have vented pole pieces.

Take the driver out, push at the dustcap through the magnet. Use the blunt end of a pencil, should do nicely.
