Cheap Speaker "Isolation" Solution for 300 lb. Speaker


 Good Afternoon All,

I am looking for advice on a cheap and simple isolation solution for large, heavy (325 lb. each) floorstanding speakers. 

I've read much advice on granite or marble slabs, multiple layers of cork, springs, etc; while this has been helpful, it is neither a cheap or simple solution. 

Ultimately, I am looking to protect my wood floor from damage these very heavy speakers might do, as well as decouple the speaker from the floor in order to reduce bass resonance (I am in an apartment complex and worry about noise complaints). I've looked into sorbothane pads, but they never seem to be able to hold this much weight.

Thanks!

Another vote for Herbie’s. My speakers are 265 each and I use the Herbie’s on a ceramic tile floor. Allows them to be moved a bit if need be and seems to isolate them well. Lots of interesting discussion on “isolation”, coupling etc.
I have gaia under my tannoy arden.... Bit my speakers only 45kg so middle of range. The difference is huge... Can play pretty load and feel bass in chest but nothing in feet. 

I live in tenement flat Glasgow built 1880 so large proportion but with gaia neighbours comain 'less' 
Speaking of Diamonds there are the Shun Mook Diamond Resonators to consider. Nothing transfers energy faster than diamond. Yes, I know what you’re thinking: why would you want something resonating in the room?

Let’s try this again:

The thing that is closest to equivalence of final result (of 2 Hz) when using the diamond dampers, is a precision/lab grade anti-vibration wideband safe table.
