Duke makes some excellent points - and he is right on when he says that the most important thing is to correctly match your amplifier with panel speakers. I have no idea whether or not your amp will match well with Martin Logans, but Ascents are not overly difficult to drive so you should be okay.
I have heard Ascents in a room almost exactly the same dimensions as yours, and they will sound just fine. Odysseys and Prodigys probably need a little more breathing room than 14' of width, and you will need to move your listening postion forwards and backwards a bit to find the sweet spot, but this won't take too long to accomplish.
Two more points - first, Martin Logans are not the sound for everybody, but if they are your "cup of tea", don't waste too much time talking to people who don't like them because they hear music differently than you. This is not a slam at anyone, it is definitely a "different strokes for different folks" issue. Instead, spend lots of time listening to other speakers to try to find something you like better. If you keep coming back to the panels, then you will know that you are a Martin Logan guy. I am a Logan owner, and with my gear, in my room, Logans (CLS IIz) are the answer for me. If I were to move to another listening space, I might change my mind.
Second, a subwoofer is not necessary with Ascents, but if you are a real "bass hound", you may eventually want to go that route. Martin Logan makes a decent sub, but there are other brands that may do the job as well. If you decide on ML speakers, give them a few months of breaking in and getting used to before you get too worried about a sub.
Happy Hunting!
