Tell us about those bases for the 3's. They must be about the size of a hood off a Buick.
... and of course, "can you hear a difference"?
Ha!
It’s come up many times before, but because it’s you, Alex!
I have a suspended wood floor that is super spongy... either wide joist, thin floor board, or both.
Regardless, I knew vibrations were going to be a problem.
Short version, after researching a lot, I came to understand that neither isolation nor coupling by themselves were a solution. The combination is.
Outrigger bars, concrete scrap from a local custom concrete shop, and isolation feet: this is what I did for my subs and Phil3s.
The concrete counter tops that were rejected by the shop were in their bone yard. I found two pieces of similar thickness and color, they cut them for me, drilled them out, sealed them... all for a very reasonable contribution to their holiday party.
The isolation feet handle most of the direct energy transference, the concrete pads deaden most any residual mechanical energy transference that the feet don’t, and then the outriggers couple that system to the floor.
The only things these don’t prevent is rattling from extreme LF Waves.
The subs, directly on the floor rattled things. The subs on concrete directly on carpet rattled things.
The introduction of the outriggers, when they were finally delivered, changed everything.
It is not so much that the sound improved because of all of these things, rather the sound improved because I removed a significant amount of residual energy resonating in the structure of the house.
I will never be on board with claims about magical sound improvements from isolation and coupling...
...these aren’t going to make well designed gear sound better still. They may, as they did for me, help ease other problems (which are easy enough to describe with words like “tighter bass” and whatnot).
