Pushed in Textile Dome Tweeter

Archived from groups: rec.audio.tech (More info?)

My son accidently pushed in the textile dome tweeter of my new speakers. I
took a band aid and pulled it out lightly with the sticky part. I know this
may sound anal but if I look close I can see a spec the size of a dot still
pushed in a little but there is no tear. The speakers sound fine. My
question is, could the tweeter be damaged in some way even though it sounds
fine at this time.

Thanks

Most likely the sound will not be effected. But, you can probably order
a replacement from the manufacture.

It's probably not damaged but probably not working the way it did
before either.
Next time use some less sticky tape, like Scotch tape or masking tape.

I've used the vacuum cleaner trick described by others and some domes
will respond to gentle warming. Don't use the vacuum cleaner at full
strength.

There can be some fabric stretching that cannot be popped out. Since
your "spec" is so small, let it alone. You'll probably do more damage
in an attempt to achieve perfection.

With very specific testing you may be able to find some defect in the
tweeter's performance. If you plotted the 3-dimensional sound output
over a range of frequencies, you might be able to find a difference
between your tweeter and an undamaged one at a few specific frequencies
in a few directions.

If you have a sound test CD with a frequency sweep, play it through one
and both speakers and compare the results. Don't expect both speakers
to sound the identical -- even if they are both in perfect operating
order. (Even if they were identical, both speakers can't simultaneously
be in the same location.) Precise speaker measurements are very
difficult. Listen for extra tones or buzzes. Since one tone at a time
is being presented to the speaker, you should expect only one tone out
of the speaker. Note that *ALL* speakers will rattle and buzz if you
push them hard enough. Also, you may discover some buzzes in your room.

One last suggestion, although it's probably overkill by now. Being that
this is textile dome, it's possible to pierce it with a thin, sharp, hooked
object; and work out the dent. I've used a staple to do so. In one case, I
closed up the hole with a dab of rubber cement...in other cases it was not
necessary.
