I have suspended speakers for years. Suspension of subwoofers eliminates all kinds of floor vibrations for a start, and the speaker is decoupled from the structure of the room. I would definately give it a go, be careful as subs can be very heavy. You have to make sure the rope or threads (I have used very strong fishing line) can take the weight.
subwoofer suspended from ceiling?
I have an open trussed ceiling. I am thinking about suspending the subwoofer between two trusses. My question is as follows- will the quality of sound be negatively impacted if I move the subwoofer from the floor (concrete slab) to a suspended location up in the ceiling? Thanks for your help.
