I have tried best to input data in Bassbox pro 6.

However the vent box is not in normal shape

the front width box is 218.2 mm but the depth is shorter 149.4 mm.

Normally, Cabinet will have depth longer than front width.

Can anyone help? :confused::confused:

I attached parameter and output in attachment section.

A few points come to mind:

1/ Before the 1980s, that was how most speakers were sized.

2/ Put the driver on the narrow face of the box you mention. It won't make any difference to the internal loading.

3/ If you don't want to put the driver on the narrow face of the box dimensions BB6 has calculated, then tell it to maintain a fixed volume setting (RTFM ;) ) and simply adjust the width to whatever you want it to be, letting the software recalculate the height and depth for the calculated volume.

4/ If you don't like any of those options, take the volume and vent dimensions BB6 has spat out, and use those to size the box yourself.
RTFM = Read The Flipping (or other words to that effect) Manual. ;)

For the other, it's in your own screenshot. Select internal dimensions, and ensure 'lock vb' is ticked. Change the width (dimension 'B') & let the software adjust the others.

Alternatively, as I noted, just put the driver & vent on the narrower of the faces you state above. It won't affect how the box performs with a cabinet this small.
