I received, but have never installed, the Audio Selection cones underneath my Lorelei’s. I’m concerned about the ‘stickum’ on the cones not holding them in place if I were to move the speakers around. Has anyone had this problem when using the cones? I haven’t looked at the bottom surface of the cabinets, but am assuming there are no threaded receptacles there for spikes / cones. Has anyone experimented with affixing any other type of spikes or cones underneath their Lorelei’s?
