TAD 4002 crossover advice

80.163.52.21

A friend got a set of TAD TD-4002 2" 16 Ohm drivers with 800 Hz exponential horns (TAD clones), plus TL-1601a 15" 8 Ohm woofers in Onken cabinets.

It is possible to use a 1. order 6dB/octave filter at 800 Hz, or would it have to be a 12dB/filter at that x-over frequency?

We found these online calculators:

The horn is 110dB, the woofer 97,5 so a damping of 12.5 dB is required. According to the Lpad calculater above, this requires a serial resistor of 20 Ohm, and a parallel resistor of 5 Ohm. What do you think?

Would it be a better solution to use an autotrafo, and what does that set up incorporate, and does it sound better than (high quality) fixed resistors?

He will eventually consider other horn types, maybe a 400 Hz, and other cabinets, suggestions are welcome.

Thanks in advance for any help!
