Hardware stores stock "furniture leveling feet", some of which have the same threads as your spikes. Essentially, it's a bolt with a disc-shaped footer at the end. Serves some the same purpose as spikes, but easy to slide. Bring your spike so you can match the thread & bolt size.
Alternative to Speaker spikes
My Silverline Sonata's MK.lll come with spikes that screw on but I prefer not to use them because of carpet damage, and they make moving the speakers nearly impossible (Speakers weigh 110lbs. each). Are there rubber feet out there anyone can recommend that will do the job of spikes? Please keep in mind the weight of these speakers.
Thanks.
Thanks.
