I'd say 430 Hz approx.

An excellent guess. It was actually 431Hz!

Now I see how stupid I was not to see where the crossover frequency was. I've recalculated the values with a shift factor of 0.69606 and the schematic can be seen below.

An externally hosted image should be here but it was not working when we last tested it.


The peak is now at 123Hz and crossover at my desired 300Hz.
