I'm looking for speaker stands that are higher 45" or higher. I have found a pair at audio advisor that is adjustable to 48" and can be sand filled. However, the weight limit says 15lbs and my studio 20's are 28 lbs. a piece I think. I don't have the wall space so I have to have the tallest stand available as I like the surrounds to be above my head and a little behind the listening position. I think there is one over at Omnimount 400 A/H series that look a little more solid and look like they could handle more weight and are adjustable to 45". What is everyone using or suggest?
