Talk:Why do my speakers come with spikes/@comment-31022905-20171228225155

But you do not want your speaker cabinet to 'couple' to the floor mind you!

The cabinet was designed for a certain response at a certain input, and your flooring was not considered in this design process. The response of any well designed speaker is best when it interacts with the listening room as little as possible. Apart from room modes you should avoid exciting, and from excessive reflection and absorption, that also inlcudes not using your solid floor as a resonant baffle.

So, spikes are useful to keep your cabinets from taking a stroll around the carpet and rubber feet are useful to keep your cabinets from coupling with a solid structure, like floors made of stone, wood, tiles, etc. (Reason why Genelec, for instance, supplies rubber decouplers with all their monitors.)

Coupling to the floor may raise your LF-levels, but only so at the floor's resonant frequencies and mulitples thereof. Meaning you get spikes (pun intended) in the LF-response at frequencies the recording artist did not intend!
