question about box volume

[rd22]

I noticed on the parts-express speaker enclosure specs it says VB=1.25 cu ft and V(total)= 1.366 cu ft. What is the difference between vb and V total? Thanks in advance.

Part number, or link?

It means net internal volume for your first number and the second volume calculation includes the woofer and port displacement. So make your box is the recommended volume, PLUS the displacement of the speaker and the displacement of the port if applicable. I'm sure those numbers will now make sense
