Martin Logan 11a vs 13a


Hello-
First post on this forum and new to all things related to good audio, though I have heard some great systems. I've started to build one up (albeit super slowly). My question is I really like the martin logan speakers and narrowed to the 11a or 13a. My current room is 14'x28'x8' tall and the speakers would be on the short end. However I may build out a new room that is 24'x28'x12' tall with speakers on short length. I have no specific genre of music, I truly listen to it all and enjoy it all and like now the ML renders the sound. I am also not a fan of too much bass. I also listen at relatively low to medium volume and don't go high volume.

Would the 11a be too small for the future room, would the 13a be too big for my current room. Right now anything would be an upgrade from what I have but looking to get a speaker set-up I'd be happy with for 4-5 years even if the new room ends up getting delayed. Appreciate the forum's thoughts.

In my old home, the listening space was very similar to yours, 22 x 14 x 10.  I originally had ML ethos with the 9 " panel.  I upgraded to Montis with 11" panels.  They were perfect for that size room.  My new home has a much larger living area, 18 x 28 x 12 and is open to other areas of the house.  The Montis still do ok in that room, but I would rather have the 13's.  Even the 15's would be better, but they are really huge, and at that price point, there are lots of alternatives.
Get the 13's.

You want the 13's  for more panel and definitely bigger woofers. After trying the ML Theos, I've decided If I go for another ML  it will be with 12'" woofs/bigger panels. I will also consider the other brands like Magnepan or Sound Labs.

For maximum bass performance, minimum 2 subs with whatever setup.

Neither model will be "too small/ big". The 13's will just eliminate future audio itch for "whats better". I recently picked up a pair of Theos, just to see if I'd like the ML sound in my room. I do, and am selling the Theos to go big. My room is similar size, with speakers on the short wall, about 7 feet out.
