Essentialaudio - The copper foil I'm referring to is 1 inch by 1/2 inch. One per window. Non-conductive adhesive.

Understood, Geoff. Copper foil is good for shielding, and I suppose as long as it's completely adhered to the surface on which it is mounted such as a window, its acoustic effect should be small. But aluminum foil rattling in the breeze is quite another thing. We're still laughing about it. You would, too. |

Bungee cords are used in many Engineering grad schools as an inexpensive but effective solution. A Bungee system can achieve a very low resonant frequency. It helps considerably to know which bungee cords to select and how to implement them, naturally. |
I know a guy who suspended his CD player on bungees from an aluminum ladder stretched across some crates several years ago. It didn't sound very good, sucking the life out of the music. Later on he scotch taped aluminum foil all over the walls, so that should tell you something, even though that's another story. Ironically he jumped into the industry making racks and stands using stacked up blocks of Sorbothane inside the completely enclosed shelves that couldn't be opened without destroying them, compressed under the weight of the component, later with threaded bolts through the shelves to compress them and prevent the stacks of Sorbothane from buckling, which had caused some shelves to collapse (structural engineering 101) and outraged early customers. As he made the exterior cosmetics fancier and raised the prices through the proverbial roof to become some of the most expensive on the market, the performance improved some but was still fundamentally compromised, as Sorbothane is intended for use in impact absorption, not steady state vibration control and isolation, not to mention the constraints on movement of the platforms mostly to the vertical direction. Don't do it. You probably won't like it. |
This is too funny. I thought I was the only loon (or at least my wife thinks I am). I came across an ad here on A'gon for a device that basically "clamps" your equipment to some sort of base or plinth. Sort of like a big wood clamp. In the category of vibration control, I guess. It got me to thinking about use of a bungee cord to do the same. I ran a bungee cord under the hardwood plinth my CDP sits on (the plinth is on 4 anti-vibration pads so there is a gap underneath it) and hooked the two ends of the cord over the top of the CDP (have a rubber piece under the hooks to keep them off the top panel). Seemed to clean up sound a bit...at the very least - it did no harm and cost me virtually nothing. Have floor standers so not needing to anchor them. Glad to hear someone else thinks they help with coupling (which is what I assume is going on with your speakers too). |
Under the theory that if it cost more it must sound better I'd recommend an upgrade to Rok Straps. They are a great product, I use them for motorcycle touring and they have the advantage of being flat so that they don't roll like round bungees. |
