Re-purposing tweeter diaphragms?

[Cohoangler]

I have a question on tweeter diaphragms for my Heresy II and kg series speakers.

 

I’m starting the process of upgrading my HII with new crossovers and titanium diaphragms.  However, there is nothing wrong with my HII’s.  In fact, they sound just as good as they did 25 years ago when I bought them new.  But since it’s been 25 years, the caps are likely at the end of their useful life.  So I’m going to be replacing both the crossovers and the tweeter diaphragms, per the advice provided on this forum. 

 

However, I also have a set of kg 3.2’s that I bought recently at a second-hand thrift store.  I don’t use them much, but they are functional.  They sound okay, but there is distortion from the tweeters, particularly in some high notes.  My sense is the tweeter diaphragms are bad.  They need to be replaced.   Bob’s website indicates the replacement tweeter diaphragms for the HII is the same as the kg series. 

 

So here is my question:   If I replace the tweeter diaphragm on the HII with titanium, can I put the old HII diaphragms into the kg tweeter?  

 

I ask because there is nothing wrong with the existing HII diaphragms.  If they are interchangeable, as Bob seems to indicate, can they be re-purposed for a kg speaker?   I’ve never replaced a tweeter diaphragm, so I’m not sure if this can be done.    

 

Okay, okay…..  I already know that I should just order two sets of titanium diaphragms from Bob.  But I’m trying to improve my speakers with existing equipment before I buy more. Plus, I’m cheap (my wife tells me that every day…..).

Yes.

I'll give it a try, and report back.
