Ah, SeaQueen, thank you!
I posted that question specifically hoping that you would answer.

Without actually looking at any data or thinking too hard about this, my physical intuition is that the arrays shouldn't be very good at detecting signals with wavelengths larger than the array itself. So... dropping the minimum frequency strikes me as a bad idea.

That was my feeling as well, I don't think the sphere arrays on submarines are THAT large, compaired to what can be achieved in the size of the flank or towed arrays. However, the ambient noise should be considerably less on that sensor given the ownship shielding and flow-noise reducing nose cone design.
Thank you thank you!
You're the best!
Cheers,
