Hello,
I'm new to the forum today. However, I thought I share a Planar speaker build I did last year for a friend.
So friend of mine hands me some 6x9 three way car speaks he had hanging from his HVAC duct by the magnets for about 10 years. He says, "can you build me some speakers with these?"
I created cutouts to rear mount the driver to a a plexi sheet that fitted to 3D printed feet. I angled them back to make the stable and not forward heavy. For wiring I used 14AWG wire to a terminal block. I did not wan the wire direct to the driver connections to prevent pulling when running the wires.
I attached REW SPL charts for these. As you can imagine they don't have a lot of low end. However from about 400 Hz on up they have really good separation and sound stage when listening to them with music. They really need to be paired with a sub. My kids were asking me why I was shooting phasers in the basement! I think that was when I was running the sweeps for the charts. 🤣
In the end, he loved the speaks. He says they are the nicest desktop speakers he has used. 🙂 After all, what are friends for if not to make crazy speakers for you.

Welcome. Hope you enjoy the community.
If you want to improve the low-end extension at some point, an EQ app on the computer (if that's the source) or a passive response shaping circuit could be used to counter some of the dipole cancellation. You could probably get pretty good output down to 100 Hz or so without much trouble. With a passive circuit you do lose significant voltage sensitivity though.
