the abv data as been collected from pioneer site, below is a cutout from w257 manual, i would have pasted all the cutouts of pioneer woofers but i dont remember the link from where i downloaded those

abv, range of enclosure size is given, use the middle value for better performance, u can see from the pic below that extreme values are not really as good.

also the given graph in the pic is not the actual output of the woofer, rather it identifies the characteristic of the encolsure.

well something i tried with my pc sub enclosure to reduce its boomy sound, i stuck a paper towel roll's center cardboard material roll some way into the port, so port is lengthened outside the box as well. No boomy sound now. Its more defined and accurate! weird.....
