Yeah hanging from pipes mounted to the ceiling Joist would be sonically much better, all things considered(should strongly consider finding best sonic placement "in space first"). simply letting the speakers "hang" wouldn't sound so good, unless the speakers were "so heavy" they wouldn't react much to movement in the speaker.
I would "X" the hanging idea with chains, etc, yes. I mean, if the speaker is haning there anyway(obstructing walkways, etc), you might as well "hard mount" the suckers!
