If you need to support two relatively heavy loudspeakers, check out the Pyle Pro Universal Monitor Speaker Stands, offered here as a pair. These stands are engineered out of steel to be rugged and reliable. The height easily adjusts from 34 to 53", and the 2mm speaker platforms can hold units up to 90 lb each. Atop the speaker platform sits antislip rubber grip speaker pads.
Lock the tripod legs in place, and their rubber-capped feet will provide stability without scuffing up the floor. A safety support pin assures the stands will stay in place, as does a lock-tight tension knob. When you're done with the stands, they can fold down for easy transport.
