Basically its a room of dimensions 10 feet by 14 feet by 19 feet or scaled down with the same proportion.
This would give the best spread of "eigentones" or standing-wave distribution for a rectangular room.
Any "normal" household room (unless its a fully damped and super dead sounding recording studio or similar) would have standing waves due to parallel walls and other geometrical factors. The idea is to try to spread these standing wave frequencies evenly thoroughout the audio band, then they may be more easily corrected/treated with stuff like Roomtunes , bass traps, Helmholtz resonators, RPG products, big wads of padding, chicken-egg carton trays, etc etc etc... and yes ... even with a small round piece of wood called "Shun Mook" that some people swear by it. (Please don't ask me about "Shun Mook" but Google it up, have a listen if possible, then form your own opinion about it
Tuning the listening room is perhaps the hardest part of hi-fi and the part that most people tend to overlook.
Basically, I would go for a room dimensions thats got just the right amount of liveness, and ideally flat freq response and no peaks or suck-outs in the audible range. Of course, speaker placement and listening position are also part of this equation.
Then there's stuff like the mathematical "golden ratio" ( something advocated by Cardas & gang) and the string of Fibonacci number sequences and how they apply it to hi-fi such that resonances won't built up etc etc etc...
Anyway, people can do (and have done) a PhD out of this whole topic alone; so if anyone is interested to know more... Google is your best friend.
Its from RH's book, the "complete guide to high-end audio" now in its 3rd or 4th edition already i think.

Robert Harley's top choice dimensions of 10-14-19. Tell me more??
That's one serious stuff you've got there mugenfoo...
