Default 7.3 pushed in dust cap

Hi,
I bought Alpair 7.3 to build Frugal Horn MK3. In transit one of the driver's dust cap pushed in. Can it be fixed? Will it affect the sound? Or I need to ask for the replacement? Help please.

Thanks
Badri

If it was indeed a shipping accident, get a new one. I have yet to hear reports of what that will do to the sound.

i ever got my driver's dust cap pushed by a random brat
what i do, is cut a duct tape for a few cm, then put a part of the duct tape to the pushed dust cap, then pull it slowly..

also, hold the dust cap to prevent you pull it way too strong..

I doubt you will hear any difference, some people do this as a modification.

really? - we have more than a couple of MA metal drivers with mush less severe damage on cones that we've set aside

maybe Mark should pipe in on this one

at the very least wouldn't you want matching "modifications" ?

Yes, ok for a plastic or paper dust cap, but this looks like a metal one. A powerful vacuum cleaner with an appropriate nozzle to just cover the dustcap might be an idea, but I doubt it would provide a low enough pressure to pop that one back out!

If I received a new speaker with a dust cone pushed in like that I would definitely be p'd. Do you have any recourse with the seller or shipping company? If it was shipping then you would think the box would have been damaged in some obvious way (or some evidence of it having been opened).
