Yes Fibreglass can be ejected out of the port - not really ideal for domestic use.if fibreglass damping is used inside a ported cabinet instead of the polyester, can the air flow from the port cause particles to be emitted and cause health problems? What do you think?
Wrap the fiberglass in an old pillowcase or other scrap cotton.
Bagging fiberglass in a pillowcase would be adequate to prevent quantities of glass fibers being ejected from the port.Will this be sufficient to prevent emission of fibreglass particles in a ported speaker?
Volume filling a reflex boxWhy are you adding stuffing to a ported speaker?
fiberglass will not do anything to damp panels.
If fiberglass is fairly transparent to low frequencies, why would fiberglass stuffing reduce sub output?Bagging fiberglass in a pillowcase would be adequate to prevent quantities of glass fibers being ejected from the port.
Using string stapled in a zig-zag pattern over the fiberglass also works.
Fiberglass is effective for keeping upper reflections (above 400 Hz or so) from being heard through the ports.
That said, this is the Subwoofer forum, fiberglass damping in ported subs used below 125 Hz or so generally reduces output and does little else, as fiberglass is fairly transparent to low frequencies.
So, was it the fiberglass filters that gave the smokers of KOOL cigarettes lung cancer rather than the tobacco LOL?NEVER use fiberglass nor mineral wool (rockwool): they are carcinogenic.
The fibers can be really small so they have to be completely sealed. Pillowcases and such are absolutely insufficient.
You can use other damping materials; there are other nice materials.

Sorry, I didn't realize subwoofer drivers didn't produce any frequencies above 80Hz.that's about midrange frequencies this for a subwoofer 20-80hz.
