Herbies Pucks floor spike protectors...

I’ve used quite a few of his products over the years. He’s easy going and let you know what product to choose. I never use the spikes, even with carpet. He had a product years ago that replaced the speaker feet with a much better non-abrasive concept. I always try and use a wood platform under my speakers with the upgraded feet on that.
You can spend more elsewhere for basically the same concept, but why?

@jtcf ..I remember those days, couldn't afford something and my mind kicked in for a inexpensive work around. Thumbs up.
