Using these Kanto S4 speaker stands is easy. First, pick a stable spot on your desktop. Place the stands where you want your speakers. The 16° tilt is already set for a great listening angle, so no need to adjust it usually. Then, put your YU4 or other compatible speakers on top of the stands. Use the 1/4'-20 screw that comes with the stands to secure the speakers in place. This will make sure they don't move around. When you turn up the volume, the foam padding at the top and bottom of the stands will help reduce vibration and resonance. That means you'll get cleaner sound. As for maintenance, keep the stands clean. You can use a soft, dry cloth to wipe them down. Avoid using harsh chemicals as they might damage the metal or the foam padding. Also, don't put speakers heavier than 8 lbs (3.6 kg) on each stand, or it might cause the stands to tip over or get damaged.
