I have a long love for electrostats and planers. I have a pair of the Maggie 1.7s. in a medium sized room (14'W x 27'D with a 8'-10' cathedral ceiling). At first I found them to be a bit bright and used a 1ohm resistor in place of the original solid jumper on ea. speaker. After hanging acoustic drapes across the wall behind and carpeted flooring I found that I could go back to the solid jumpers. After a good deal of detail to set up and placement, I am completely amazed at how incredible they sound - a large deep stage with a perfect balance of detail, musicality and imaging. Unlike some who say the Maggies have a very limited sweet spot - my set up does not. Wether the listener is standing or setting, in center or either side of center the stage remains large and rock solid, with vocals and instruments staying firmly planted, where they belong. I can imagine how great the larger 3.7i could sound when properly set up.
Regardless of wether you choose box or planers, as others have suggested, moving your seating location in to about 8-10 ft. and doing a bit of experimenting with placement and positioning (sometimes as little as 1/2 " one way or the other) can make a huge difference in how they sound.
Best of luck Jim
