Spring Design: The speaker stand employs a spring design to prevent acoustic feedback from speakers caused by vibration. This delivers a more focused and lighter sound, while minimizing noise and vibration for an enhanced listening experience. High-Quality Materials: The audio stand is built from premium materials. The tray and base are constructed from thickened density board, with a thickened column for support. The steel tubes feature a baked enamel finish, providing load-bearing strength and sturdiness for increased durability. Anti-slip Pad Design: A non-slip sticker on the stand's bottom fits tightly on the contact surface, offering solid support. This effectively prevents displacement from accidental bumps or slight vibrations and significantly reduces sliding noise, allowing you to enjoy your music.
