This is a versatile product from the craft world - intended for hanging posters or canvases. We use it primarily to secure monitor loudspeakers to stands.
Stick this clay-like polymer to the top plate of speaker stands. Then simply place your speaker cabinet on the squares and press into place. Mechanically couples yet isolates the speaker to the stands similar to spikes without damaging the speaker cabinet. Tack-it is a non-reactive, resistive damping polymer which behaves like a tacky, flexible, semi-liquid clay. It provides excellent mechanical energy absorption.
We like this product better than BluTack.
Note: may leave a faint oil mark. A safe solvent will usually remove it. Recommendations are a guide only.
