Why are the ELS SUBs feet spiked?
The energy that is generated inside the cabinet of the subwoofer has to be dissipated somewhere. If not, it will cause colouration to the sound it produces. The best way to do this is to mechanically decouple the energy into the floor by way of the four spiked feet provided. If your floor is precious and you would prefer not to mark it or make holes in the flooring, please use the solid washers also provided, placing the spike into the small indentation to prevent it from sliding away and falling off the washer. The spiked feet are custom made for Epos speakers and are an unusual pitch 8mm thread. Do not try to use other makes of spike as you will cross the thread and may not be able to remove them easily with damaging the cabinet insert. Together with the spike, there is a locking not. This should be tightened up against the cabinet to stop the spike from twisting, once the level has been adjusted of each spike to stop it from rocking or wobbling.
