Differences among the electrostatics of Martin Logan models?

I am looking into ML 11’s. The dealer near me didn’t have a pair on hand, so he suggested the ESL X, from the Electromotion series. I was not impressed. The one aspect that bothered me the most was the disjointed  nature of the upper range with the bass. Two weeks later, the 11’s were set up in his shop. Although their placement was not optimized, the sound from the 11’s was totally different from the ESL X’s. The sound was of one piece, bass + upper range, probably similar to the 13’s that you heard.

I believe it is a mistake to go the ESL X route, not I in the same league as the Masterpiece series. I don’t know about the Summit or other similar range past models. If price is the issue, perhaps you should consider the 9’s. After much research, I have moved my gaze from the 11’s to the 9’s.

Thanks ledoux, I agree with you; the X is not as good as the 9; unfortunately, the 9 is out of my budget too, so I'll have to save up for now.  Good luck finding your ESL 9's!

If you can get them with good panels, the Monolith III was a great speaker. I have the latest panels in mine and they can't be touched for sound quality.
I always said if I didn't have these a used pair of Summits would be on my list for a more manageable (waf) speaker..

Figure the cost differently....mine are 8 years old...bought them used.....Figure they last you 12 years....divide the price you are looking at by 12 and that is your cost per year....about the same as a new iPhone....
