Thinking of upgrading to ML ESL 11 or 13a. Thoughts?

My experience is that a larger panel sounds better, not just louder (more detail, more musical, etc). It doesn’t seem to make sense, but that’s how it works.  The Montis is not that much more visually imposing than the Ethos.

Yes my SO did not even immediately recognize that I had swapped the Montis for the Ethos.  They are bigger in every dimension, but the difference is somewhat subtle.  The new Masterpiece series is noticably larger in the bass cabinet.  And yes the larger panels sound better not necessarily louder.  If you can find Montis, I can easily recommend them.  Personally, I liked them better than Summits.  The DSP seems to be the secret sauce for panel / bass cabinet integration.

Great, thanks for the responses. I may try a Tekton Moab out - apparently its great for HT usage...and if I don't like after the 60 day trial, Ill go montis maybe

And now wavering back to ML haha. I am adding more music into our routine, so maybe stickign w/ something thats good all aroudn is best for me. Would the Ethos to 11a be a substantial move? Or am I better off going to 13a for  noticeable bump?
