by inserting a filter at 1.00 kHz, 120/60 octaves wide, down -30 dB. This obliterated whatever noise the receiver was generating, all of which was above the subwofer band
Interesting that your receiver is outputting a noise around 1000Hz.

When I look at your filter (in green) I see it has almost no effect on your existing filters. That's good.
The phase (in red) only effects the crossover area by about 5 degrees, so that's good.

Too bad you had to go to so much trouble to track down the problem, but that happens sometimes.
