Using these speaker stands is easy. First, place them in the desired location. Then, attach your KEF LS50 speakers to the stands using the integrated mounting system. You can fill the pillars with appropriate materials to increase stability. When it comes to maintenance, simply wipe the aluminum surface with a soft, dry cloth regularly. Avoid using abrasive cleaners. Remember, the stands are sold in pairs, and the speakers are not included. Also, the spike disc feet are there to protect your wooden floors, so don't remove them.
