Tweeter question

[3-LockBox]

I'm talking about a 1.5" cone tweeter

One of my tweeters, a cone tweeter (old Ratshack make) has had its little dome pushed in by a curious child, but it still seems to work (the cone wasn't effected). How important is the dome (dustcap) on a cone tweeter? I have replacements, so I'm not hurtin, too badly anyway.

Sounds like an opportunity to execute a dustcapectomy and play with phase plugs. I have successfully used foam ear-plugs as phase plugs.

Hi
Sadly dents do sometimes occur. A dent in the dustcap does not normally seem to affect the sound. However to date I have always managed to pull out the dents with a pin or needle.

1 1/2" cone. Is it a phenolic ring type? Can you show us a pic?

With care, sometimes adhesive tape can pop-out a minor dent.

Its similar in appearence to the old Pioneer phenolic ring type, but its a ratshack tweeter; what makes it a phenolic ring type?

The phenolic ring is the plastic (usually orange) ring around the tweeter cone. I think it's purpose is to deal with the wavefront as it attempts to exit the tweeter. I guess it's better than the metal frame but others will have to chime in and fill you in.

If you have the RS version, it may not have a very big voice coil and popping the cap might be tough as it is somewhat of a bullet shape rather than a rounded cap. Can you hear the difference between the two tweeters?
