Ported sub: Fill with poylfil or no??

Alot of peole don't know this trick, but you can change the Q of your port by putting fill inside of it... It will reduce output, but will yield a wider bandwidth from the port...

That is why God invented chicken wire.....to hold polyfill in place....(and hold chickens in place).

For those city kids that do not know what chicken wire is....sorry.

Usually you can just glue it and it will stay in place.

I have a pair of old circa 1980 Radio Shack Realistic Optimus T-300's (34"H x 12.5"W x 13"D) sitting right in front of me here at work ... 10" woofer and a 10" passive radiator (1" tweet & _"? mid). These are some great sounding speakers! The bass is like vibrant and lively. Unlike the sealed 10" sub in my truck, which does thump pretty good, I don't have to search for a specific song to try to "demonstrate how good these speakers sound", because all songs sound great on them. Sure wish I could transfer this sound to my truck!

X2 I would love to get that studio sound in my car.
