Have you read his document?

This document is based on research data below; You can read all
the research data going back 30 years or read the simple text.
Read post #28 again. Gallo claims 'line source' when it obviously is not, it's
impossible because he's using seperate drivers {many elements = line array}.
So....Gallo claims it's a line source, but it's not. If you claim that it's a line array instead,
that's ok, but it's the worse design if you wanted to mimic it.
Don't you think it's cool to look at commercial product and analyze it?
It's educational and makes you stronger. It might even motivate a person
to build their own and it will be superior without having to spend $20k.
