Can you smell your speakers when youre rockin out?

fibreglass and polyester are different materials. The PMC and B&w used foam. Nothing like fibreglass.

I agree fibreglass is great when it comes to sound absorption but i am talking about health and safety. And what I have posted is completely relevant to the title of this thread. I am just offering my opinion on another aspect of speakers which is often not spoken about.

The fibreglass industry would suffer a loss if they started to admit it is actually more dangerous than it is often claimed.

The danger exists when the invisible particles become airborne and then breathed in.
If GMA can prove using an air particle counter that no fibreglass is released from the port when playing music, then they can claim its safe. Otherwise I would like to know how much of that stuff comes out.
If you think there is a safe limit on the amount of this stuff you can breath in, thats your opinion. My own view is to avoid the stuff completely. Its safe in the attic because nobody goes there. Its not airborne. You can easily avoid this by simply using other materials like polyester. GMA used polyester in my speakers at my request. They dont do it routinely as it takes more effort. Neither polyester or fibreglass has any effect on bass anyway. It takes much more than a bit of fibreglass, to get rid of bass energy inside a tiny cabinet.

If it was this "dangerous" don’t you think it would be unlawful to use as home insulation.

No. You cannot depend on the law. If you want to avoid air pollution, you cant depend on the law because its being broken all the time. Car pollution IS dangerous but the law does not protect me every time I go out in public and breathe in all of those fumes.
