I recently purchased a nice bunch of B&O units that came with a nice pair of Beovox S-80 speakers.  I don't know whether the seller had it or I did it while transporting it, but once I finally had a chance to try them out I found that the woofer on one speaker is a bit "punched in". Not the entire speaker but that top cone - the part that reminds me of a Studebaker. The peak is pushed in about half an inch, with a "pushed in" area about an inch in diameter. I don't notice any audio problem, but it's not right and will drive me nuts if I don't fix it.

Any suggestions how I can pull the point out so I have a proper point? I opened up the box and found the woofer has a metal "box" over its back, so I'll have to pull the tip out. I've tried various sticky tapes, but nothing sticks to the fuzzy-ish material the point is made of. My desperation move will be to poke a tiny hole in the tip and hope I can pull the point back into place, then apply a bit of rubbery liquid to seal up the hole. I really don't want to do that.

Some will think I should just put the cover back on and enjoy the great sound, but I'm too retentive for that.

Thanks for the help.

Have heard a using a vacuum cleaner may work with sufficient suction.

Those dome pieces are just dust caps for the center part of the driver.  The caps are not there any sound characteristics.  They are there to prevent dust from getting into the working parts of the driver (like the spider and voice coil).  I have used a large sewing needle to pry/pop the dome back into its original shape.  Worst case you can remove and replace the dust cap with a new one.  Speaker supply shops sell various diameter caps. 

When replacing the surrounds on old speaker drivers the cap is typically removed so the driver voice coil can be shimmed to properly align the new surround. After that the dust cap is put back in place.

I wish everything had such a simple and effective answer. It took longer to plug in the vac than to "pop" out the woofer and all's right with the world.

Thanks, all, for your help.

As to the comments about the "stack o' tronics", I can't say I disagree with much. But I got it all for a fair price, knowing that the cassette unit doesn't work and the TT makes noises I never knew a turntable could make. It needs a lot of attention. But I got an excellent remote controlled radio and CD player, which is mainly what I was looking for. The rest is a fun project for a snowy day sometime in the future.

And the S-80s sound great!
