Focal Aria 926/936

I listened to the 948 (just as tall as the 936) and the 926 in the same room for several hours before buying the 936. The tweeter height isn't an issue. I do the same thing with my 936's jerroldls does with his 948's. You'll be listening a little further than I am. My biggest worry would be the size of that room. You will have exaggerated bass in that room with 936's. If that was the space I had to work with I'd certainly have got 926's 

Canibefrank,
I for one couldn't care less about anything Tekton makes. Kinda tired of the Tekton fanboys trying to be the marketing department, too. When you buy Focal you know you're getting grills and the same parts in the speakers every time. Not so with Tekton. 

There is no increase in bass output from 926 to 936.  All you get is tighter bass due to it being able to use three drivers not working as hard and the fact that the crossover point is lower also frees them up to do a better job.  The other aspect you gain is a slightly lower bass reach.  

Definitely not MORE bass.  The only more you get is the ability to play a little louder.  

Huh.... I've heard the 906, 926, and 948 all in the same room. That certainly wasn't the case. The 948 was vastly superior in bass depth and volume. That room was probably 4 times larger than what the OP is working with. Indeed in an anechoic environment they're all going to sound about the same to 55Hz, but the room is going to reinforce the bass more severely given it's size. My room is about 14 by 23 so I can avoid some of the corner reinforcement he's going to be dealing with. I feel in that room those things will still be making decent bass below their -6dB low point. I don't know what the OP wants for bass. I want clear, muscular, fairly balanced bass and in that room I'd put 926's if it was my money. I came real close to doing that when I bought my 936's and only didn't because I knew I'd have a bigger room at some point. 
Looking at anechoic measurements of the 936 and 826W, it's obvious that the 826W has half the hump in bass response that the 936 does. I would expect the 926 to perform almost identically to that. I think that reinforces me point. 

I’d feel bad if the OP ended up passing on the vastly superior 936 due to your comments. The difference between the 926 and 936 is not bass output, period.

I also have no idea why you kept mentioning the 948 as they have zero relation to the question and are so different from the 936 it’s almost as if they are a different speaker line.  Then you go on to bring up the 826, which is literally a different speaker line.  

Its midrange quality, bass quality, and bass depth. Very simple.
