The Ascendo’s weigh about 275 lbs each. The stands are filled with about 50 lbs of silica sand for a total weight of approx 120 lbs. I recently moved and although the speakers break down into 3 manageable pieces, the stands were rather heavy as we opted not to remove the sand.
I first heard the Ascendo System M at CES around 2005 and was really impressed with their sound but new these are quite expensive so I had to wait until 2014 before the price came down enough for me to afford them. Two of my other audio friends also own a pair of these.
