I have used the design they were referring to a long time ago and did other variants of it. I drove the Tympani IV through those initially in all their ear shearing glory, aided by the thin bright Bryston 4B NRB. I later made a separate tweeter speaker lines with a simplified version. The complex weave of Venhaus' (sp?) design is not necessary for the bulk of the benefit and it brings out the brightness even further.

Satie, thanks for your input. I always very much enjoy reading and learning about the experiences of knowledgeable inmates such as yourself. If you haven't already seen it and have the time and patience to read the Ven Haus story, it can be found here:

Those were the instructions I followed.
The results are a very good but brightly balanced cable, which I think the OP would appreciate for his tweeters..
You need to fine tune the aspects of positioning from offset from the front wall, to your listening angle (meaning as determined by your listening distance) ,to the spread between the speakers, and tweeters in vs.tweeters out. Once you have these things aligned as well as you can for your preferences then start experimenting with absorption and diffusion.
Instead of watching for tonal shifts and focusing on timbre, you should find a well regarded recording where imaging is known to be very well done. Then do the fine adjustment of the positioning for image related issues, soundstage size and width and depth as separate aspects, image specificity and solidity and detail retrieval. These are all better when the speaker's time behavior is closest to good alignment.
So long as the room is essentially raw there will be tonal balance issues as reflections balance with direct sound.
Thanks, Satie - can you suggest some recordings?
A good listing is provided by these audiophile sites.

We recently had a discussion about recordings with interesting soundstaging

There is also this discussion where Stereophile test CD 2 and 3 are suggested, I use #3 for some testing and have done so since the mid 90s.

Personally I use The Stravinsky Haitink ballet suites recordings, Modern Jazz Quartet the last concert, Vivaldi La Stravaganza on L'Oiseau Lyre, Billie Holliday's last recordings (stereo), Benny Goodman's live recordings from his 1958 European tour. Decca Ashkenazy Beethoven Piano Concertos, Telarc Beethoven 9th Symphony and the early Karajan DG Beethoven symphony cycle, and a few others used more for late fine tuning once you are closer to being done.
I got the speakers 6 feet out from the front wall and I am making progress. Seems like sometimes I'm sitting closer that what would seem "normal". There is that distance where the direct sound and reflected sound reinforce each other. And the timbre changes with the amount of direct sound. What might happen if I lined up my guitar amps on the front wall behind the speakers? More absorption and diffusion. Vocals are a little thin right now....
Diffusers are a common treatment behind planars. I'd recommend however that you decided where you're going to keep them first. With 1-D's that can take quite a while! Then you can try some QRD diffusers at the first reflection point of the tweeter panels on the front wall (where you see them in a mirror when seated at your listening position).
Thank you, Josh358, for your insight! I have a lot of experimenting to do.
Good idea of the amps on the wall behind the speakers, and if possible the guitars too. They will act as diffusors, a good thing for the rear wave of Maggies. The distance between the T-I's and the wall behind them will create different interaction between the front and rear waves, leading to varying degrees of comb-filtering. Trial and error will be necessary to find the optimum position to minimize that.
