subwoofer buzz - how to eliminate it

MartinLogan Dynamo 700w 

At low frequencies, it vibrates, like it wants to fall apart. It does have a rubber feet, sitting on a hardwood floor, what could prevent it? Isolation feet? More rubber? Also it's facing the floor but can be turned sideways, would that help?

This may be a long shot but check the mounting screws for the drives I did this for my two powered subs and was surprised how many were lose Hey I do the same for my tower speakers

Doubt that was it, but always good to tighten lose screws especially on a sub woofer
