Quick question, cuz Im a little confused. When you punch the numbers in the port calculators and it tells you the length, does that mean length of all the ports added together, or each one needs to be that specific length?
Like, if I put 3 4" ports in a 4.2 cube box, http://www.mobileinformationlabs.com/HowTo-1Woofer-Box-CAL%20Port%20lenth%201.htm says they need to be 18" long. Is 18" total for all three (6" each) or 18" for each tube?

I divided it up so mine came out to 27. something i divide by 4 and thats each port and it seems to work lol bt i am not builder more elecitrical kinda guy

09-02-2009, 07:38 PM
its each port. if you divided by 4 then your box is tuned really high
