Near full range BMR (Balanced Mode Radiator)

I confirm that I am still in that price range plus shipping costs.
However, my idea was to exploit the characteristics of the BMR speakers to make pendant speakers rather than something to hang from the ceiling where my wife cannot easily reach to move and put aside like she does with the bookshelf speakers they made. 5 times around the room... 😡

the question is? Are two 3.5 inch BMR speakers enough to provide sound from above in a 16 square meter room? or would it be better to move to 4.5 inches rather than 6.5 inches and have greater extension towards low frequencies?

Is this an idea to discard or does it make sense?🤔
