I'm driving myself looking for stands for my old Yamaha speakers. They are built like a tank (only about 2-3ft tall) and, hence, too heavy for any of the new mid-height speaker stands. What I had (until the feet broke) were just some very low MDF "platforms" that raised the speakers a few inches off the ground and angled them up a few degrees. Anyone have any idea where I can get something similar these days? Brick and mortars are useless apparently so any web directions would be greatly appreciated.
