Coupling or isolating floorstan. to the floor?


Best thing to do with heavy floostanding loudspeakers on the tile floor? Spikes vs Rubber feet. Whereis best place to buy spikes?
Thanks!

Because a speaker cone is coupled to the cabinet, the cabinet will always vibrate to some extent with the cone. This causes a dissipation of energy which can result in loss of efficiency as well as phasing inaccuracy. So the idea is to hold the cabinet as rigid as possible so (ideally) all the work is done by the cone and none by the cabinet. Now it seems that vibrapods may hold a cabinet more rigidly than if it were standing unrestrained on the floor, but they cannot hold it as rigidly as spikes can. Am I missing something here?
awdeeofyle: ya got me how the aurio's work (or even IF they work). I'm actually a skeptic of many of the tweaks on the market, including most isolation devices. Of course, I can respect someone's differing opinion. Having said that, I certainly do believe in SPIKING speakers for the reasons said. I can also imagine a theory as to how the Aurio's work although I cannot believe they work as well as spikes, particularly when efficiency is at issue.

Here's my theory: when speakers are flush on the floor, the cabinets move slightly in reaction to the cones moving. If the friction coefficient is not exactly the same for each speaker, each speaker will be affected slightly differently, causing a slight phase shift. Because the Aurio's are ultra low friction, and because they are machined with such low tolerances, any two speakers are more likely to vibrate in phase with eachother. How's that?
