All speakers in a cabinet have a resonance. It's perfectly normal.
For a bass reflex it has 2 jumps. One from the speaker in the cabinet and one from the reflex port.
See picture. Blue line.

So if you see in a closed cabinet 1 jump it's OK.

I agree with Piet; The resonance peak of these woofers will be somewhere between 55 and 65Hz in this volume but that's an educated guess. If you want I can do the measurement on my set but that will take some digging. These are not the only speakersystems in the house. :mrgreen:
Since the crossover frequency is arround 500Hz an Fc of 55Hz to 65Hz won't be a problem at all! :wink:
