You're right about the Delta 12LF and some tube amps. The trouble is that a notch filter probably won't help you. You can try it, and the way to calculate values is with the standard reactive formulas for capacitors and inductors. But sadly, I'm certain you'll find it is of little value.

I recommend that you either run the woofers with a separate amplifier, or perhaps substitute a Delta 15 woofer in place of the Delta 12LF. That of course will require a pretty large box, so it may not be your favorite option.

Sorry, but I'm afraid those are the best things I can suggest. But I think you'll find one of them will satisfy you, and it's better than attempting to use a notch filter to solve this problem.
