I don't understand frequency response readings for the Asgard 3.

On the site it says Frequency Response: 20Hz-20Khz, -0.1db, 2Hz-400KHz, -3dB

I'm trying to figure out what -3dB. Does this have to do with the gain switch?

Is low gain -0.1dB and high gain -3dB or vice versa?

I would like to get to the -3dB for that 400KHz frequency range even if humans/most humans can't hear past 20Khz

It means past 20hz and 20,000hz it starts trailing off at a slope of -0.1dB/octave. So for every octave below 20hz and above 20,000hz, the response only trails off by 0.1dB; by the next octave, it's at 0.2dB; then 0.3dB, and so fourth until you hit 2hz and 400,000hz. At which point it starts trailing off at a sharper -3dB/octave slope. For reference, most 2-way speakers are most usually crossed at 12dB/octave, with some variations from -6dB to-24dB (although in some cases the low pass and high pass slopes can be different and the the frequency where the cut is applied might have a bigger gap between them).

Basically, what that actually means is there's practically no difference in effective range from 20hz to 20,000hz...assuming whatever you're listening to actually even has anything past 20hz and 20,000hz.
