These two On-Stage studio monitor stands are built with heavy-duty steel construction and sturdy hex-shaped bases, perfect for elevating studio speakers and monitors without vibration and rattling. The stands adjust from 36.5-54" in height to customize any listening area, and easy one can safely hold speakers up to 90 lbs. Rubber feet and EVA rubber on the platform add stability and shock absorption when installing on wood, tile or other solid floors, and six leveling carpet spikes can be installed for extra stability when using these stands on carpet.
