It would mean that 1-st order filter is properly implemented (-3dB fall at 250Hz). The other filters no so well. I have to admit that different types of filters could have different definitions of cut-off
Not -3 dB.
Crossovers are -6 dB/per per order / per octave. So 1st order is -6 dB per octave....4th order is -24 dB per octave.
Here's what I don't get:
Why would Devialet implement this in such a non-intuitative way?
