having a cnc router is very nice. i used to work in the cad dept. at a company that made store fixtures and i used to use their router to cut all my boxes. you could lay a full 4'x8' sheet on there and it would cut the parts perfect every time.

wrong. the loudspeaker101 calc dosent take the correction factor in account. not everyone uses the edge of the box for a slot port.
if you still think they are right, try just changing the height and widths around. leave the same numbers.

here is a new box i just designed. its tunable from 23hz to 42hz. im going to make a plug for 27, 35 and 40 to see what i like.

heres my design so far. the volume after the port and brace is 8cu feet. the port is 14x3x 13" long, which should tune it to 28hz. the shorter port will be 2.5" long and tune it to 42hz. is that going to be too short?
will port noise be a problem?

i been wasting my time over there. just realized on the port calc, if you swap the height & width numbers, the answer shouldnt change cause the port area dosent change, but it changes alot. i knew i needed that formula in excel for a reason.
