Dedicated listening room 25' L X 9' H and ? W

What would be the best width for a room that is 25' long with 9' high ceilings? It is also said that non-parallel walls is the way to go. Would a slow taper of one foot in width difference be enough from front to back? (Ex. front wall 17' and back wall 16'.) Would rounded corners also help? Thanks for any help that you can give.

15.45 feet wide for a 25 foot deep room.
Use the Golden Ratio which is 0.618 = (sqrt(5)+1)/2
This is also the ratio used in the Cardas speaker placement formula.
This is a truly remarkable number with numerous websites dedicated to it:
