Help needed with Rattle in my floorstanding speakers.

That particular piece enlightened me to the fact that the voice coil in my Martin Logan ESL woofer was rubbing.  I had to get a replacement from them.  It stresses parts of the system and the room so aggressively that anything prone to rattling does.  Make sure the sound is coming from the loudspeaker first, then try tightening any screws around the drivers.  I don't think you have too many options around securing things within the cabinet.  Take solace in the fact that "Fading Sun" is an anomaly amongst the tunes that we generally listen to.

I don't know how Simon got in there but you need to get him out.

Perhaps you need to change the floorstanders for something smaller he can't get into.

Without knowing what speaker it is, I would suggest removing the grilles (if any) before going further. Some grille frames are steel or aluminum and may very well cause an audible rattle if not secured against the speaker or if the frame came loose at a joint.

If the drivers are tight, and it's not them, the most likely culprit is a loose wire.  After that a crossover board and lastly cabinet component.

I really think it is one of the scenarios mentioned above regarding loose wire or so. I will remove the drivers and check this weekend. 

probably a wire routed too close to a bare wall or a driver magnet.  take each upper driver out.  As you pull it out note the wire routing and look for the source of the rattle.

I tighten my drivers yearly, mine have removable backs and all drivers are fastened from within.

Otherwise, you will need to remove them, I would do them all at once, perhaps adding bullet connectors in-line for easier access.

If insulation, you can remove existing, partially or all, and replace with polyfill, I got mine from Walmart, one small bag expands to a heck of a lot.

Once, when a woofer was facing down (speakers on 8" high open base, a buzz turned out to be a staple that had fallen out and landed on the back of the cone. i.e. you never know, just be thourough.

Could be a crossover component vibrating. 

Is the wiring secured inside the cabinet so it can't "rattle around"?

I just checked all the screws and looks secure to me. 

are your drivers secured to the cabinet....I had a B&W that had a loose mid

I was listening at very moderate volume and I can only hear the rattle on the upper part of the speaker were it house the tweeter and the midrange. The bass woofer is located at the bottom of the speaker. I only heard it on this particular song.

Well... in listening to this I believe the quietness of the music caused you to turn it up too high and you fried a woofer. Liked the bass though.
