Your favorite Electrostatic, Panel spkr

I entered a high-end music store in the early 1980s in Oklahoma City, just to compare what they had to my great Altec Lansing Flamenco 848a horn and large woofer speakers. These rocked and shook my walls. I was in my early 30s with a limited budget. I saw a pair of tall skinny screens in a frame with a large tubed amplifier attached. I asked what they were and was told that they were electrostatic speakers. They were Acoustat or Martin Logan, I do not remember which. He turned them on and I was blown away. I had never heard any speakers that were so realistic in the midrange and treble. Instruments and vocals were so real I could feel their presence. I had to get them. I asked the price and was told I would have to get the amplifier and the speakers and the combination would cost somewhere between $8,000 and $10,000. I was extremely disappointed because I knew I would never be able to afford them. I left the store and dreamt about those speakers for years. I eventually forgot about them.
In early 2017 I was in Best Buy with my wife and saw a section of the store that was labeled Magnolia. It was a Hi-Fi and TV store. We were thinking about getting a new TV so we went in. After a while, I entered a separate room that had a number of speakers with McIntosh and other amplifiers. They also had a pair of tall skinny screens in a frame. I know that my heartbeat got faster, my face flushed, and I froze and stared at my fantasy speakers. All the memories came back and I just stood and enjoyed the Deja Vu. I asked the attendant to connect them and they sounded as good as I remembered and/or fantasied about. The sharpness, clarity, musicality, detail, speed, dynamic range, separation, soundstage, and solid bass were marvelous. I compared them to the Bowens Wilkins 800 D2 and other high-end speakers and there was no comparison. The electrostatics were so much better in every category that was important to me. Even my wife, who has hearing aids, also noticed and enjoyed. Her hearing has gotten progressively worse in the last 20 years. She has been unable to enjoy most music in the last 10 years because the speakers she has listened to were not clear enough. These electrostats changed this. We now listen to concerts and musical shows and she enjoys what she is hearing as well as I do.
For me, nothing I have ever heard is better.

I own ESL63s and have enjoyed them for about 5 years,  even in a "way too small - that will never work" bedroom converted to a listening room.  I thunk that room is even smaller than what you are describing. I drive them with an Innersound Electrostatic amplifier. 

For those who assert that Quads can't do bass, i can only say that when i got my new Supratek preamp the bass went way deeper. I now use them in a much larger listening room, and their sound has improved.

For your room and style of music, I believe the Maggie 1.7s or 1.7is with well integrated subs, would be incredible.
Over the years I've had many very nice speakers, but developed a particular fondness for stats and ribbons. For many years I had and very much enjoyed a pair of Quad ESL 63s. In my 14' x 26' with 10' ceiling, audio room, I now have the Maggie 1.7s with a very well integrated single ADS sub and the sound is amazing. With a bit of time and attention to set up, the little Maggies can present a very wide, deep, detailed and focused stage - both in and away from the sweet spot.  
I'm considering moving up to the larger 3.7i, or possibly the Sound Lab 645s,  but that would mean a need for more power and the 1.7s sound so very good driven by my 100W Rouge integrated tube, I'm not sure the gain would be worth the cost.
I can not imagine that you would be, in any way, dissatisfied with the Maggie 1.7s in your space.
There are a lot of good suggestions here for various other very good speakers, but If you do choose the little Maggies and would like some helpful suggestions on set up, feel free to PM me. The idea that ribbons and stats can not image out of the sweet spot is not true.......Jim

Jim, your Rouge integrated amp will have no trouble driving 645s to a reasonable level probably louder than the Maggies. However the 3.7i is an incredible speaker for the money. It is purely a financial decision. Either speaker will benefit from  subwoofers down the road. 

Mike,

I don't want to hijack the thread.   Yup, the panels are curved like the ML’s.    The total speaker height is 75-3/4” and the panels are approx 13” wide by 65-1/4” tall.

thanks.
