Can I suspend / hang speakers?


All right, I'm setting up a home theatre for dad (father's day and all), and he'd prefer to suspend the rears from the rafters rather than have stands. It seems...well...you know. Can someone give me a sound technical reason this is a bad idea? Thanks. -Dave

inpenin- I agree with your comment on intuition. Point made. However, I do not believe that allowing a speaker to move freely in space (even a small amount) is beneficial to good sound. I must admit I will NOT hang my 90 lb Merlins from the ceiling when they arrive to experiment.
The movement of the enclosure will indeed be small, but given the generally universally accepted goal of rigidly mounting speakers, why in the world would you hang them in space, to let them move (swing) on their own? Imagine a recording with bass almost entirely in one channel, with large excursions of the woofer and small excursions on the other side, sending the imaging info all to !@#$. Remember that our ears/brains use millisecond delays to localize sound. YOu would't consider mounting speakers on a columnar spring which could move around in response to the driver motions; isn't this similar to what you are considering by hanging them? Maybe one of our speaker designer/builders could chime in. Maybe my intuition is completely wrong here.
Non-rigid mount would be a bad idea, since the speakers would move in the opposite direction as the cones, according to Sir Issac Newton's First Law of Thermodynamics (at least I think it #1)- for each action there is an equal and opposite reaction. Only a little bit, but think how hard we try and make sure that speaker stands are rigid.
Thank you Wade- Its been over 30 years since I studied any physics. I was just guessing on which law. I'll gladly take you word for it.
