The Markwart crossover(s), as example, set the VHF at max and adjust the balance by increasing or reducing the amount of compensation.

I don't believe you have enough headroom to do the Patten HF boost.

Build the "T" filter using tabs 1 and 2 of your 8-Ohm L-pads for the adjustable resistor, and use that to balance your lows and highs. Tweak your Zobel for the smoothest response through the crossover region.

With that, I think you're done until you go active....
