RE: Sub isolation.
You may want to look into some appliance isolation feet. I got a set of 4 from Amazon for my HE washer I put on my second floor. Before the feet, (they're simply a dense hockey puck type thing, with an extra layer of far less dense material touching the floor) you could clearly feel the washer during spin cycles. Afterward, the vibration is greatly reduced. I wanna say I paid about $50 for a set of 4 of these.
It's my understanding, that for isolation decoupling type devices, that a certain density of material must be used to effectively "shock absorb" whatever weight it is that they are carrying. A 100 lb. subwoofer could likely be compared to the weight of a running washing machine.
Then again, I have a Wedgie, and it works really well for bass amps that weigh quite a bit.
Ah well, back to the screen thing. |
