I own Innersound Eros Electrostats which have flat panels like yours, I dont run mine anymore but still own them so here is what I learned.
As you know they need room from backwall, 3ft atleast but side wall is not very critical because of the narrow dispersion, placing items behind them to break up the backwave is very helpful.
When aiming the speakers I used a flashlight help next to my ear in my listening seat, when you see the beam reflected in center of panel on each side your in!
Also if they have spikes or feet you can lower the fronts or rears and play with the angle they fire towards you at, this can help define the soundstage and its height.........very useful.
You are going to need to use a Vacuum cleaner on that ESL from time to time......scratch that and please refer to owners manual, I will only say mine needed cleaned with a hoover every so often, the sound can get dull and cleaning them helps again look at your manual but I can share how I did things if you wish.
If I can help feel free to contact me, cheers
