should speakers be coupled or decoupled?


I have seen a bunch of threads that touch on this, but I wanted to ask the question directly: I don't understand the idea of putting ball bearing type decoupling devices underneath floorstanding speakers (with or without a platform). Doesn't this mean that the speaker will move around as it's woofer fires? And isn't that decidedly not good sonically?

I do understand the idea of having a very solid base for the speaker: either spikes down through carpet to the base material underneath, or a solid platform.

I'm very interested in people's thoughts on this matter.

Markphd, I understand what you are saying and feel that your logic is sound, but recently I have read reports and reviews from credible and reliable sources that claim that the use of a decoupling device such as Symposium's Ropllerblock jrs., can and do outperform spikes, when placed under a loudspeaker. Now a device of this type, basically a ball bearing of some sort sandwiched between two discs with a concave surface, will allow a fairly large amount of movement of the speaker cabinets, even if they are fairly heavy. Do you have any theories as to why this result may have been reported? Are these people hearing things? I certainly hope that, one such as yourself, wouldn't go down that road as it would seem to be, well for a lack of a better term, a cop out way to explain what these industry professionals report to be hearing.
