In order to create an effective soundstage, I want to suspend side speakers for a 5.1 or 7.1 system at different heights, relative to the ceiling, because the ceiling slopes to a lower level over the soundstage on the right side.Attaching the speakers directly to the ceiling would leave them at significantly different heights,relative to the listener.  The side speakers are not adjacent to any wall and I do not want to run wires under rugs or drill through a hardwood floor, hence, the ceiling.  Any suggestions on products and methods that would result in an aesthetic result?  I am planning to use nanosat prestige speakers.  Thanks.
