With my somewhat limited experience with speakers utilizing a ribbon tweeter I have not found this to be an issue, this "head in a vise" scenario. Perhaps because the full range, three way towers I have listened to are approximately 44" inches tall? IDK, they are quite wonderful sounding. I do realize everyone's experience can/will be different .

Hi Strider. When photobucket stopped 3rd party hosting my build thread was pretty much gutted. The last dozen pages or so in the thread Bridgman linked pertain to the speakers. Here is a pic of how they turned out. I built three as an LCR set for behind our screen wall. Pretty nice for movies.

Serenity Now, wow they look great! Hope they sound as fine as they look. What ribbon tweeter did you use?

It's disturbing that I knew the answer from memory (I really enjoyed the build thread), but IIRC according to the plans it is this one .

It occurred to me that the degree of "head in a vice" behaviour would probably be a function of the mid-tweet crossover frequency, but it's too late at night for me to remember whether higher or lower is better.

Yeah that's the one.

In this design it was crossed at 3500hz I think to the Mids. I think the designer uses a rule of thumb of filtering a whole octave outside of the drivers "safe" range. I think the tweeters could be crossed at 2500hz according to the manufacturer.
