When I got my unit I had a similar side-speaker buzz/vibration thing going on. I took the speaker out (very easy to get to 4 screws on the grill in the side cut-out, just keep a hold on the speaker from the other side as you remove them) and discovered that there were splinters from the edges of the hole cutout that were protruding and touching part of the speaker cone/surround. Sanding those off and replacing the speaker cured the buzz for me. Definitely worth checking. Interesting. So you took the side speaker out completely to do this? Removing the grill from the speaker side and the screws from the back side? Oops, yes, remove the speaker with screws on the back side. You may not need to remove the grill side as the issue with the splinters was only on the speaker side.

I just received my SSv3 yesterday and I had a harmonic vibration buzz out of the box coming from the side speaker only. Upon further investigation, pressing hard on the cabinet next to the grill would stop it, but tightening the screws didn't help, so I removed the side speaker and discovered painted splinters around the edges of the cutout that had been rubbing on the speaker surround when mounted. I filed them off, remounted the speaker and everything is fine now. I notified Aspen about it, but thought it might be relevant to you folks here, in the context of zaphod's question. Now the fun of finding the best location in my room to get the best bloom (and bass).
