Modern bookshelf speaker stands made of glass and aluminum create a striking accent in any room. The glass top minimizes vibration and is supported by an aluminum column that hides the wiring. Rubber decoupling feet beneath the stand lend stability and further reduce vibration, increasing the quality of sound. For carpeted rooms, floor spikes can be substituted for the decoupling feet. The unit weighs 22 pounds, making it substantially lighter than comparable steel units.
