I lost count of how many 4 spike speakers and speaker stands I have owned and I never had a problem with leveling. If you are going through carpet you need to apply enough pressure so the spikes will penetrate the carpet and pad. If the floor under the carpet is wood rock the speaker back and forth while applying pressure so the spikes will sink into the wood floor a little. You have to use caution if your floor is concrete because rocking on concrete can damage your spike tips.
