    Misleading Title! Def not for TWEETERS
  

*by N***N on Reviewed in the United States on December 5, 2020*

Incorrect title! These rings are not made for tweeters at all. These are made for the mid-bass in a 3-way setup. The description does have the measurements, but people search for what they need by name AS IN TWEETER! Not by measurement

### ⭐⭐⭐⭐⭐ 







  
  
    Great
