  Is the 30 ohm resistor on the tweeter L pad correct as intended?
  Thank you again.

    Yes of course, all parts are as intended ;) You can adjust that resistor to taste if you like, but should replicate Dan’s design very well at 30 ohm. If you find the speaker sounds too dark/dull, increase to 40 or 50 ohm will bring up the tweeter level slightly. If you still want more treble at that point, remove the resistor entirely.

    Looking at the simulation again, I actually wouldn't bother with 40 or 50 ohm as I suggested. If you find that you want a bit more presence (forward sounding), just remove the 30 ohm resistor and try that. If you find the speaker a bit too forward, try decreasing that resistor value to 20, 15, 10 until it is just right.
    
    If you want a bit more top end sparkle, you can adjust the 3 ohm resistor to 2.5 or 2 ohm to taste. The values I posted were intended to reproduce Dan's crossover as closely as possible, if it were me I would probably go with 2 ohm and 20 ohm in the tweeter circuit based on my preference.

  Thank you for your post on the Wavecor 4 ohm crossover variant.
