Paul and hennfarm, let's say the primary is only 10H. I don't know the typical DCR, but I'll check this evening after work. For now, I'll assume 500 Ohms. If I drive a signal across that inductor using a generator with 100 Ohms output Z (similar to the followers I have in mind), 20 Hz response is down only 0.26 dB relative to 1 kHz. If the inductor is 20H and 1k Ohm, 20 Hz is down only 0.13 dB. This isn't as good as 50H or larger, but I'm still thinking the concept might be viable.
