im would like to know if port are is THAT important. freind of mine has a BL 12, he wants to buy a box that another friend built, but the port area is under 12 sq inches per cube. the sub that was in the box before sounded pretty good. just wondering if the port are being a lil small is restricting output or SQ in any noticeable way. its off by like 8 sq inches. thanks

If you are off by too much not only will it change the output but you will hear it huff air. I really, really despise the sound of port chuffing.

is the chuffing caused by too little or too much port area. or is it both?

too little. i figured it would "chuff" or you would hear some port noise. but it didnt sound bad before. i think hes just gonna try out the old box and if he likes it he'll buy it, if not we'll make a new one. thanks for the input.
