The AT-ST3 speaker stands position your AT-SP3X or other similarly sized bookshelf speakers for optimal sound projection. Made from rigid alloy steel with vibration-damping cork feet, each stand provides rugged support for a speaker weighing up to 3 kg (6.6 lbs). The stand’s speaker support surface is layered with urethane foam to further suppress unwanted vibrations and is angled at a shallow 13 degrees under the assumption that music will be enjoyed a short distance away from the speakers. The angle also prevents sound waves from reflecting off hard surfaces, which can negatively impact audio quality.
