Anyone know of reasonably priced speaker stands that are 12" tall, about a 10"x10" platform, with little or no tilt and that will support 90 lbs?
Try the guys at Mapleshade. If they haven't got them, they'll probably build them to your spec.
How about these filled with sand?http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=240-748
I have a friend with those stands and I have even borrowed them for playing "visiting" speakers. They are terrific!
My buddy uses a combo of sand and shot.
If I was shopping, I'd start and stop right there!
