I'm with sdbimmer...sdbimmer said:I wouldn't use water, it's messy and it'll ruin your box. Use foam popcorn or sand. Then transfer it to a measuring cup. I think that how people are doing it.
Yeah - get your box volume then figure out the port. Then use the chips again to measure the port volume (the part that will be in the box anyway) and recalculate to see if you have to fine tune. Also don't forget the woofer basket!PLAZAMAN said:i can figure out port later right?
If it's not a huge box, this would work out rather well I think.kwang125 said:i put big trash bag in the box like the way i put trash bag in the trash can. then, i pour liters of water in until i fill the box. this way, the box will stay dry.
ps. i use 2 layers of trash bags to be safe.

No, the port changes as the box size changes. The problem is that a certain internal volume can give you some crazy port size, like 4" dia x 36" long. Get with someone who has a box design program or download one to plan this out.PLAZAMAN said:Jae... Im trying to port an odd shaped box.
Are you saying for example if i want to tune a box to 33hz... 33hz of port will be 1 size no matter how big the box?
