“You can try these Pads can are good up to 60 lbs per square inch. thats 960 lbs per individual pad. 4 PACK ANTI VIBRATION PADS ISOLATION DAMPENER SUPER HEAVY DUTY BLUE 4x4x7/8 | eBay I have used these under speakers and to also isolate my TT
free shipping also 2 packs should be enough for both speakers at a cost of $26.00”
These are good products and you can get them with cork instead of plastic in the middle, and I use them everywhere damping is needed, e.g. clothes dryer, garage air compressor, heavy isolation transformer, and my subwoofer. A word of caution is they’ll leave black streak marks if placed directly on light hardwood floors and loaded with heavy objects. If you decide to go this route, make sure you place a thin layer of something like plastic wrap between them and the wood floor.
