Used Sanus SF26B1 Black (Pr.) 26-inch Steel Bookshelf Speaker Stands. They are very sturdy and can handle a bookshelf speaker up to 35lbs. They are in great condition, but there is a small chip in the metal down on the base of one of the stands, which can be seen in the picture. They have adjustable steel carpet spikes.
Note! The way to get the best speaker response with these stands is to place them (steel spikes) on concrete slabs, and use 1" Dia Sorbothane Hemisphere Rubber Bumper Non-Skid Feet to limit vibration between speaker and stand, and to keep the speakers from moving.
Great stands without having to spend a fortune. I tried many wooden stands, including Sanus, and they all ended up in the trash eventually. These Sanus steel stands will last a very long time.
I've been selling on Craigslist for about 13 years with no problems. I guarantee everything I sell, so if you aren't satisfied bring it back for refund.
