Ethan: Thank you for ModeCalc!

Welcome! Need support, you got it. Or share you ideas and experiences.

Hello Ethan,
I have been reading your Acoustics FAQ, and I've just been playing around with ModeCalc, which is very handy. Thank you!
As I have posted before, I am in the planning stages of constructing a listening room/home studio in my basement. The height I have to work with is 8'5" (measuring up to the underside of the floor above), and I am in the fortunate position of being able to decide the room's length and width. The *maximum* dimensions I have to work with are 24'8" and 16', respectively.
I understand that ModeCalc presents a list of room modes for each dimension, and provides a graphic presenting the same information. As I understand it, I'm looking at two things: (1) the spacing of the modes, which I want to be as even and as spread apart as possible, and (2) modes that coincide or come close to doing so, best seen in the graphic when lines of two different colors appear one on top of the other.
I do want the length and width of my room to be as great as I can make them while still being as acoustically advantageous as possible, so what I've come up with is a length of 24'8" (my maximum), and a width of 15'11". According to RoomCalc, this gives me a ratio of 1 : 1.89 : 2.93, and a volume of 3304. I only see one instance graphically of modes coinciding (represented by colored lines one on top of the other): 134.26 (height) and 137.43 (length). The mode distribution, while not perfect, doesn't look too bad to me. (Please let me know if I'm deluded here!)
Have I missed anything important, or does this seem like a good plan for my room? In any case, thanks for the FAQ and the ModeCalc program, Ethan. You've helped make some complicated ideas much easier for a relative neophyte like myself to understand.
