 IB subwoofer cones are "unloaded" at all frequencies. Excursion is the limiting factor. If you run out of excursion, you need more displacement. Many IBs generate clean output down into the single digits. The DC filters in most consumer electronics serve to high pass around 5 Hz, which works out very well.

I was thinking the same thing.
I can get well over 90dB at 9 feet at
10Hz (RS SPL meter
uncorrected) from my 4 x 15" IB with virtually
no cone movement at all.
One day I'll double the number of drivers and finally get some
real bass out of it!
I don't need a high pass filter. I just need more turbo boost!
