i have 1.6 maggies and they are dipolar;i recently bought 2 fake ficus trees and put them behind each speaker.they diffused the sound and killed the slap echo.the sound wasn't deadened and the soundstage remained.
use of absorption material can have an adverse effect on the sound,so use it sparingly.
in your case ,you could use them accross from the speakers on the far wall.the cost is only about 40$ a piece.
