Confused about RE calculator

[jdawg90]

On the re audio calculator i have the "port length 2" set at zero and the port is 16.5" deep but it says total port length: 27.5

How is my 16.5" port 27.5"....

what are all your dims, ill try it out

i think i know what it is.. the port is measured down the center, not along your port wall edge, thats why it looks weird on that calculator

how would that change the port length?

dimensions are

48w x 19h x 24d

port width: 7"

Port length 2: 0"

red mark is how the port length of wood is measured, you have to calculate the whole line for the total actual port length

so even though the red mark is X long, thats not the whole length of the actual port

lol, thats like a dual port?

i could be wrong, but i was always shown that the port was measured down the center of it, no matter how many curves or turns it had

[edzy]

yes, correct, but the pic threw me off. it looked like 2 ports, side by side.
Anyway, on the calc, it should just give the total lenght. Why ist 27? idk.

with it like that the port length is 24... re says total is 27.5

im stumped

i agree, idk :confused:

unless they are calculating the remainder 3.5" (half your port width) out into the box for some reason...:confused:

Re calculator ***** *** :fyi:

RE's Calculator is known to be alittle off.
... It's good $hit though.

[edzy]

well, i ran it, and it shows in the cuut sheet, 2 pices that size. Maybe a dbl port wall? idk.

Looks like its measuring the outer port wall.

Alot of people say the calculator is off, so i would use a different one.
