Only the beginnings of an idea I bring the ideas - it's up to *you* to implement them !  They say > insulates and sound deadens I assume it could isolate and dampen kit and could have sonic benefits Someone brave or (stupid ?) enough could try spraying it inside the case of kit with plenty of air space and of course the airflow still left clear Maybe a layer for kit to sit on Damping in speaker cabinets, on it's own or with other material Anything else ? |

Don't mean to patronise you, but be really careful with this stuff, we use it sometimes at work and it is the messiest, stickiest, most uncontrollable of all products.
GOOD LUCK !

I wasn't volunteering, hoping someone else would ! Came to mind as we found various holes in our factory unit to be filled yesterday We'll do that first and gain experience I've seen builders use it and it was messy but blocked the gaps. Best if out of sight |

I don't think it's the right stuff to use inside a speaker, for 2 reasons:
1. it sets pretty hard so might cause internal sound reflections etc.
2. are we sure the chemicals don't have an adverse effect on the speaker cones ? I have heard that the fumes created as it cures can eat away at rubber surrounds.

Sounds like a double no for speakers then
Deadening cases then may be all

We used to have a laugh filling each other's tool boxes with this stuff. Took bloody hours to clean out!

Umm, Not packing, or for spraying around in enclosures, but backbox chamber volume reduction! Lightweight, absorbent and cheap!
Take it from me, I've used it - there's baking parchment and clingfilm protecting the driver / cone / box whilst the foam is setting - once set and the skin is removed it is a foam - quite good absorbency actually. Left to cure properly before fitting. I also use a layer of felt around the cone for damping - 1.5 years on still doing the business on several pairs of mid bass horns;)

Yes the protective items can control it well. Once dry and hard pretty much harmless - unless exposed to heat, like say a power supply or power amp ?

Not sure if it is flammable, it's often used to seal cable ducts.

So maybe a use is growing somewhere
Remember the lunatic who first mentioned it !

Oh yes.
Think they used it when they turned over the tyre place next door to where we used to be

It's useful for dampening the ringing of an inner sub platter, such as those once used by Thorens on the TD125 MkII.
It might even work on a Sondek if you can work out a way of containing the foam once it starts expanding.

It might even work on a Sondek if you can work out a way of containing the foam once it starts expanding. I would be more inclined to use self adhesive automotive bitumen sound deadening panels cut to shape for that application. It can also be used to dampen the suspended sub-chassis. I used it very successfully on a Thorens TD150 which, many years ago I tweaked to bring a considerable improvement to sound. |
