For the early reflection points I generally recommend 2 (4'x4')panels for the each side wall and ceiling (cloud) but one in each area can work also. For the back wall it really depends on how much of a problem you have and what you are doing for as far as design/budget. http://gikacoustics.com/early-first-reflection-points/
Also one bass trap in each corner is a good start but plan on adding a lot more.
A "Cloud" necessarily means hanging a panel on the ceiling 90 degrees above the speaker all the way to 90 degrees above the listening position? Or just the reflective point On a ceiling where one can see the speaker from the chair??
Same goes for sidewalls?? Is it good enough to horizontally mount a 4'x2' panel such that It covers both points on each sidewall??
I guess not much can be done with respect to the floor except laying a thick carpet, when the ceiling points are treated that way??
Also, is placing the chair, the starting point & then place speakers by measurement ?
