I am sure you measured the speaker and you are correct about the measurements. What I would like is for someone else to listen for themselves without the network and report what they hear and measure. All parts in series or in shunt affect the sound. Even the resistor type in the shunt network will affect the sound. I have never heard any part in a shunt network of any kind that was totally transparent.....except maybe very small values (couple hundred picofarad) of copper foil props from Amtrans. I am not saying that Tyson or anyone else will like what he hears without the network.........but what if he likes it better? It does not hurt to try and listen and learn. I am mostly in the less is more camp as I know from over 40 years of listening tests that nothing is transparent and the less parts we can use.......usually results in better sound. However, not always. In this case? Only those who try with open mind will know. There can also be other ways to tailor the response other than adding a network....you already know this. For instance, some people listen to computer audio with a player that has EQ built in. If they use very little of it, it could be way mo betta than a bunch of distorting passive parts.....maybe. Then there is felting and baffling and on and on. Maybe adding a thick felt pad between the midranges would tame this. There are many paths up the mountain.
