Gerald, On my FireBox at 48000s/s, the 25 Hz filter is 25 Hz at -6dB, and at 96000s/s it's about 50 Hz at -6 dB. It's substantially wider at -40 dB too; I couldn't measure it much more than about -40 dB because of lack of dynamic range with my setup. I'll email anyone who wants to see some plots with the DSP buffer at 2048 and 4096, sampling rate 48000s/s. Ask. 73
