acoustic ceilings

My room is 15d by 9 wide by 8 high. I have scanned the internet re room acoustics and have a good idea of side\rear wall and floor treatments. Previously, I was going
to use a supended Armstrong ultrimo ceiling (basically 703 with a facing, but I read some feedback saying this would deaden the room (all absorbent). There is no "w" i.e., WAF,
so I would consider the hanging panel method, if anyone could direct me to an affordable application or D I Y ideas,
I would appreciate
