MS-90-36 studio reference monitor stands are 36" tall column-style stands made of sturdy, Series 6000 aluminum, and are designed for both exceptional support as well as practicality and style. They feature three internal cable channels that run the length of the column, giving you the opportunity to run a power cable and audio cable through two, while filling the third with sand or shot for even more stability.Speaking of stability, MS-90-36's feature four non-marring sound decoupling pads that also help keep your monitors more stabilized regardless of their size (up to 75lb. each). They also have two rubber couplers between the column and the top/bottom plates and spike decoupling designs under the top and bottom base plates for even better acoustic isolation.
