Using these Kanto S2 Desktop Speaker Stands is easy. First, place them on your desktop. Then, carefully put your YU2 or similar - sized speakers on the stands, making sure they fit well within the minimum and maximum base, depth, and weight limits. Adjust the speakers to the 16° vertical tilt for the best listening experience. When it comes to maintenance, keep them clean by wiping with a soft, dry cloth. Avoid using harsh chemicals as they might damage the aluminum or the foam padding. Also, make sure not to place overly heavy speakers on them as it could cause damage. If you move them around, handle them gently to prevent any dents or scratches.
