Notch filter power handling question.

[Music is life]

When a speaker rated at 300 watts uses a notch filter like this:
3.3 ohm (10watt), 125uf, 52ml (120 watt) are those values (resistor, coil) good enough for the 300 watt rating? (I'm thinking that the notch filter does not draw much power)
Are they good enough for a 600 watt rating?

Trying to get my PA midbass horn good enough to use when EQ is not possible.
Thanks in advance.

Cap ratings are based on voltage, while what matters most for the coils is DCR; it should be no more than 5% of the driver impedance, and usually when you get the gauge large enough to realize that it will have adequate power handling. The resistor is what's hardest to call, you have to calculate how much power it will drop.

EQ is not optional equipment.
