Zilch,
Here’s what I plan to do tomorrow, let me know if I’m missing something:
All tests nearfield and with 902 on dummy load. Tests 1& 2 with inductor at N-800-F output only, tests 3 & 4 from both x-over input and output.
1. 20mH shorted, both woofers playing.
2. 20mH in line, both woofers playing. (Video at change from short to in line.)
3. Helper alone, coil at N-800-F input.
4. Helper alone, coil at N-800-F output.
I think I should dummy load 16 Ohms at main woofer for #s 3 & 4, yes?
Unless I missed something, next one will be with M-19Z.
