MartinLogan ESL 15A review sold me on the panel, worried me about the seats

Read through the Renaissance ESL 15A review and the engineering still fascinates me. A 15 inch wide curvilinear electrostatic panel running from 300Hz all the way up with no crossover in the middle of the vocal range, roughly 690 square inches of radiating area, and a diaphragm quoted at 0.00048 inches, about an eighth the thickness of a hair. Below that it hands off to two 12 inch aluminum woofers covering 22 to 300Hz, each with its own 500 watt amp and its own enclosure, run by a DSP with Anthem room correction available. One power cord for the whole thing, which is a small mercy on a speaker that needs the panel energized.

It sits second from the top of the Masterpiece line, which runs from the $7,500 ESL 9 up to the $120,000 Neolith. No price for the 15A in what I read, so I am not going to guess at it.

Here is my hesitation, and it is a home cinema specific one. Everything that makes a big electrostatic magical for one listener works against a room with three seats across. The panel is deliberately controlled in its dispersion, so the person in the middle gets something the people on the ends do not, and a dipole wants real distance behind it, which fights with wherever your screen and center channel want to live. MartinLogan sells centers for exactly this reason, but a panel center under a screen is its own compromise.

Anyone running big MartinLogan panels in an actual multi seat theater rather than a two channel room? Did you end up treating the front wall behind them, and how bad is the falloff off axis in practice?
