You probably know this already, but the spikes are there to puncture through the carpet to make contact with the concrete floor and keep the speaker coupled to a firm surface. You are effectively connecting the speaker cabinet to a large mass - the concrete floor.
Plonk speakers directly onto a carpet and they tend to wobble about. Remove the spikes, put the speakers onto a granite slab on the carpet and . . . . . it will wobble about. The wise ones tell us this is rather undesirable because a wobbling speaker acts like the recoil from a gun firing, because as the drivers move there is an equal and opposite force acting on the cabinet, which are then wobbling about while this goes on.
Max Townshend produces speaker supports that - wobble about, yet the difference they make to sound quality has to be heard to be believed. Touch the speaker cabinet and they flop around quite frerely which really is counter-intuitive to what we have been told for so many years.
