Is anyone aware of any health problems by using fiberglass in the interior of enclosures. It seems as the woofer pushes air thru the port, it also will spew fiberglass particles into the room as well???

Lol... Well among other things, you're at least talking fibreglass particals getting sucked into the motor, which could cause big problems.

If you do use fibreglass, try to get the oil covered stuff, it's like a weird greenish brown colour. I don't even know if they sell it anymore but I have found some in some old speakers and used to have some laying around the house. You won't have much of a problem with it.

I'd like to rise this from the grave instead of creating a new thread. Is there any substitute for the R11 or R13 insulation that does not use fiberglass? How about polyfill?

I prefer R13, real fiberglass. It seems to work best.

You know, the speaker doesn't really push this stuff out the port. When the speaker is first used, some of the loose fibers break off but after a very brief time, it settles down and doesn't give off practically anything. Just run the speaker for a few hours in an unused room for "break-in time" if you're worried about it. After that, the speaker won't produce any fibers for you to be concerned about.

There's a lot more stuff in the air - mold spores, pollen, dust, microbes, pet dander, radon, dead skin, particulates, gases, etc. A microscopic amount of glass fiber is pretty benign compared to all the other stuff in the air.

I guess I'm just scared of the fiberglass hairs flying out the ports, not being able to see them, and breathing them in.

If we use R13, is there a netting or spray that can be used on the fibers to keep them from separating and getting air born?

Is there "netting"? Sure

The X-Tra Queen Size is for hip sizes, according to the sites size chart of up to 64"!!! Should handle netting for Voice Of The Theatres!

Very Happy That is a great idea! It should be fine enough to do the job. Does anyone know if they will change how the 4pi sounds?

Make the sound a little "fat"?

Give the music "weight"?

I'm fairly new to home audio. What exactly does this mean? Is it good?
