I'm interested in this speaker. Anyone has built one and has the plan to share with me.

Many thanks!
That looks like a horn loaded speaker. I don't have details. But a guy here tried to make a pair very similar for a 5" full range driver. No matter what amp he used, the sound was very poor and well below the quality expected, ie, he ended up with "expensive firewood" so you really do need to be some kind of expert to succeed, and enclosure resonaces can be quite a bother.
I witnessed several fellows trying to make horn speakers, all failed, except those who used restored midrange and treble JBL drivers where they just renewed parts, but didn't have to do any woodwork or calculations to try to get good bass.
