Good point. An informal test was that one of my amplifiers, and Adcom 535, runs cool at full volume, with other crossovers I tried I could get it warm, which makes me think the speaker in it's current configuration is pretty easy to drive. Maybe the impedance of the woofer goes up in the frequencies where the capacitor is active. Thanks for the suggestions. I thought about adding a small value .22-.33ohm resistor in front of the capacitor to match the inductors resistance. But I can usually hear resistors so I hesitated doing so and don't have any on hand anyway.
