In Reply to: Schematic 1.7i's for a DR x-over upgrade??? posted by HappyTrails on January 15, 2021 at 09:46:08:
I posted the 1.7 schematic on the audiocircle jerk forum quite a few years ago.

That schematic is correct. I didn't have 1.7's at the time, but I do now and have confirmed it.
For those interested in defeating the supertweeter modification it's pretty easy to do. Just clip one leg of the 10uF capacitor.
The impedance drop at high frequencies will no longer be there and it won't drop below 4.8 ohms. The tweeter is in the 1.6 configuration then.
