I need some ideas on my QLS6 & 9. They are almost full with Galileo mpc's and are raised off the carpet by Hifi Pyon cable elevators but the problen I have is the QLS pivots down towards the side the MPC's are plugged into and is not stable. Does anyone mount it on a wall or anything else? I would think on a wall the subwoofer would vibrate the QLS and interfere with the whole idea of vibration control. Any Ideas??
