Need a crossover for my new 400 lb center channel speaker...

OK, here you go.
LP is: 3mH-53uF-0.9mH
HP is: 11uF-2.2mH-40uF then 6R series resistor paralleled with 4uF followed by a 9R shunt.



That takes the horn down 6dB. According to how my active crossover was set, the horn was 10 below the woofers, but that doesn't seem right from what we measured.
If you use that Stromberg amp then you can easily roll the tweeter channel in or out. The 6dB attenuation should help with the noise of the amp. The 4uF bypass of the resistor works as a shelf to tip the top end up.

Let me know how this works out. Hope you have some caps that big. The cap on my low pass filter here is about 50uF. I think I bought a Solen or a Dayton.
