@grislybutter I initially missed your comment that it's downward firing. If it were me, I would also use a subwoofer platform with the Nobsound feet on top of it to get the sub raised further above floor level. This combo together will give you cleaner sounding bass and should probably help with the rattling or whatever it is.
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?

@grislybutter Turning sideways may or may not help. You'd have to try it. Raising the height using a platform helps whether it's front or downward firing. Personally, I wouldn't bother with the slab, even though it's probably a good solution. I would just put the Nobsound springs on top of an Auralex Subdude platform for excellent isolation and a little height, and also play with placement if you are so inclined. |
@grislybutter Sure, happy to try to help. The Nobsound are going to be more classy looking than the Auralex platform. They are brushed aluminum with some shine to them, and when the springs are compressed about halfway as they should be (no more than halfway), I think they look really nice. And with the inserted black foam earplug mod, you can expect them to perform in vibration isolation better than the more expensive foam-based platform. |
@grislybutter I previously suggested both the Nobsound springs and the Auralex Subdude in part because the Nobsound feet have free 30-day returns, so you can decide if any additional isolation benefit is worth it to you. They isolate in a different way than the foam on the Subdude, so it will have additive benefits; neither solution being perfect by itself. They are very effective and inexpensive. The point made above about using three feet vs four only applies to spikes, not spring loaded feet. Lastly, the Nobsounds perform best with a foam earplug stuffed inside of some of the springs for a damping factor. Best of luck |
