Tertullus4 Pcs Speaker Isolation Feet Anti Vibration Pads with Stainless Steel Ball Speaker Pad Stand 39mm×24mm Aluminum Absorb Shock for Audio Speaker Amplifier HiFi Equipments(Gold)

I used 2 of these to elevate my Streambar! Sound seems improved to me!

Order 1 packs of 4Got 1 pack very used ones make matters worse, the feet were unnecessarily difficult to install.

My husband used the barrel fitting on his subwoofer that already had feet on it. It did reduce vibration and gave a tighter base sound.

So how do you really know if these make a difference?I am getting a lot of floor vibration on my Sub Woofer, so I decided to try them on thatsince there was no screw holes to attach these on my model Sub, I just set it on them on the floorand yes I am getting a little less rattling, so it seems that these do have a function and offer some sound isolation.The set I received is nicely engineered with good aluminum feet and ball bearings, The set is a quality made and manufactured. But they did not come with any instructions, which would be nice for people new to these king of products
