So I built a sealed box, i was super tight on space. The box ended up being .27cf inside (not excluding any space the sub takes up if that matters)

The specs call for a .35cf box. I havenít installed the speaker into the box, but with it being smaller than the specs will polly fill help? how much?? Any suggestions???

Also the magnet is like 1/8" from touching the bottom of the box (it fires up). is that a problem? should i place a small spacer between the magnet and the bottom of box?? Any suggestions???

It should be fine. Qtc of that box is .779, will drop a little with some fill.

It would be better to give the pole vent more space but I think it might be OK.

Rule of thumb is 1 lb. per cubic foot. So .27 lbs. :)

4.3 oz... so about 1/3 of that bag.

Unless of course you have to pack it in. You don't want it to be dense, ruins the whole point.

Only reason I say this is because i'm having a hard time picturing both 4oz of pf and a .27 cuft box. :)
