My living/dining room is large (30 x 35) with high ceilings and my couch is sort of out in the middle. (I know this isn't ideal, but there's no helping it.) My JBL N24II satellites are supposed to go to either side of the couch, 5-6 feet up. I've looked at speaker stands, but hardly any even go up to 58" and it seems like a light breeze would knock them over when fully extended. Any creative ideas for speaker placement or speaker stands? Thanks.
