Why do you think it's not useful for me?

This URL is a simplified formula for a series of straight pipes, so it is only valid for certain structures.
"It's just a “here's how to do it if you're designing for the first time" kind of thing, but I don't think you'll make any major mistakes.

I purchased P830985 about 10 years ago for 980 yen per piece (6.34 USD at current rate).
It was sold by a Japanese discount store from the manufacturer's large inventory.
This driver is well balanced and can put a lot of power. It is a true little giant that can be used with many different types of boxes.

I have used that driver before……really nice tone through the upper midrange to lower treble…….but sounds absolutely fantastic with a 3/4” tweeter crossed over at 5500hz
