Default Damping speaker frames

There has been mention of ductseal for damping stamped steel speaker frames. Is this the ductseal that is water based and applied with a tube gun or is it some kind of self adhesive tape with a lead component.

thanks to Cal Weldon and Dave for your replies. Have only found a water based one locally so will keep looking. Mod podge is available in most craft shops here. Thanks for the link Dave.

I think plumbers putty might be just the ticket. It comes in tubs and is really cheap also.

It doesn't work as well because it doesn't stick to the baskets.

Bostik Blu Tack also works well but I imagine not as good as ductseal.

Interesting thought.

Blu tack would sure stick well. I wonder if the diference in density would be a plus or minus to the damping factor? The obvious answer is it would be less effective but I wonder.

Have you considered a tube of Silicone Seal? Comes in cauking gun sizes if its that important to you.

I think you would do better worrying about dealing with vibration, resonance, sound wave propagation, and harmonics in the cabinet itself before worrying about damping the metal of the speakers.
