Powered subwoofers are not intended to be located anywhere but on the floor of the listening room for proper LFE production and extension. It would be an interesting experiment but as Elevick states, you'll lose a great deal of bass extension from the sub by doing this. If you do try it for the heck of it, let us all know how it sounds as compared to it located on the floor.
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.
