I agree with Audiokinesis. Three Marquee's is probably a bad idea. I tried to tweek a theater that had 3 5000c Meridian center channel speakers in the same configuration. It never sounded good no matter what I did. You have the right idea matching all your speakers, but sideways center channel speakers, in general, are a sonic compromise. Two Dynastats would be a better choice.
ET's are very directional, although they do a great job at their price point if you are IN the listening position. Move above or below the small ribbon and the highs roll off considerably. For a dedicated listening room on a budget they work well.
If you want some dynamics with wide dispersion electrostatic top end in a smaller package, you might look at some used Gallo Solo or Reference II's or III's.
I sold SoundLab, ET, Gallo and Meridian.
