well nobody would answer my bassbox pro question so can someone just check my design and tell if it comes out to what i think it should?

here's the design:

http://img150.imageshack.us/img150/4365/8cube35hz5nw.png

also there will be 6 wooden dowels (2" in diameter and 18.5" tall) inside taking up .202 cubes and my subs should displace .36 cubes

all those dimensions are external btw and i will be using 3/4" mdf for the box and port

basically bassbox says after all displacement the box should be 8.177 cubes tuned to 35.11 Hz

is that right?.....if not please let me know what u calculated it to be....thanx

that port looks way to short to be tuned to 35hz or whatever in that big of a box.

I don't know much about ported boxes but the dimensions don't seem to match up...

you are way off

to make that box right make it only 20 1/4" deep and make the port 10Hx10Wx17 deep

according to my BB6 :)

A pen and paper and a regular calculator.

A pen and paper and a regular calculator.

did u account for the sub displacement and the bracing displacement as well?

8.122cuft

34.26Hz

assuming 20 degrees celcius, and 30% humidity...

:p


:crazy: :crazy: I don't like BB6... it always lies to me

for 8cu ft (including displacement of things) I get

20 x 41 x 20.57 on the box, exterior dimensions and
17l x 10.1w x 10.1h for the port @ 35.9hz


For 8.177 @ 35.11hz it wants
20 x 41 x 20.94 and
17.5l x 9.974w x 9.974 h on the port

:crazy: :crazy:
