No my friend, you are wrong; this crossover was designed by a crossover engineer who was working for a company that sold speakers. It is a 3-way 4th order crossover, T-type.
92 DB efficient.
What I'm listening to has solid firm bass.
These are the capacitors that are in the bass leg of my crossover.
