Davey, Thank you.

But I still could only assume this was applicable to the i's.

Understand I am leaning on the knowledge of others, as I am a noob but capable of following directions (sometimes!)

If one peeled the skirt up on the i's would that tell others of knowledge more?

Are you dissatisfied with the sound of your 1.7i's??

Dave.

  Davey, No. Quite happy.
  
  But if it improves on something already good then why not :)
  
  I'm a man of constant tinkering.

    Nothing wrong with tinkering, but a guy like Danny Richie would not be tinkering with any of my speakers. :)

      But here again, a noob like myself, and the improvement DR did on my 600's I have respect.
      
      I'm open to upgraded parts.

  Davey why would one would want to modified the 1.7 super tweeter to revert back to 1.6 status? Curious! Thanks, Sam

    I don't consider it a super-tweeter because it doesn't extend any higher than it already would. It only changes the polar response of the speaker at the top end because the tweeter is now 1/4 the width.
    
    But, the main reason people might consider switching back to the "normal" configuration is the impedance drop at the top end. It drops down to 1.3 ohms. If you disable it, the impedance is 4.8 ohms minimum.
    
    Much would depend upon the power amplifier used though. Some might not have any issue with that impedance load.
    I'm not advocating one way or the other. Just mentioning that's very easy to reconfigure it.
    
    Dave.
