My expectation is very low when buying products that drastically undercut the price of the main players. If I want a good product I never buy the cheap product. I might not buy the most expensive product either. Also, in this time of supply issues, a lot of the junk Chinese products as well as high quality products need to source components based on availability. For a product like the one you discusses, the main/only driver in sourcing components is price.
SVS SoundPath Subwoofer Isolation Feet
I like to have these feet around to play with on various speakers/subs and I even put them under an AV cabinet. I just bought two new sets and noticed they’re SIGNIFICANTLY stiffer or "harder" than previous versions. Older ones are more "squishy". Has anyone else noticed this? It kinda shows me there was zero thought or engineering to them except to make something rubbery and bouncy and charge a bunch of $ for it.
