We're all familiar with the requirement that our systems accurately reproduce every audible frequency from the lowest to the highest.
But what of those bass frequencies we cannot hear but we can feel?
We don't hear earthquakes but we certainly feel them. Or the rumble of a faraway train, the rush of 1Hz air from a falling object, or the 10Hz thud of a foot pounding on a wooden stage.
If we're in the room we hear and feel all the pressure waves below 20kHz.
Wouldn't it makes sense to reproduce those too?
I would hope that any reference level HiFi system would take seriously the effort at full range audio—not just the expected 20Hz to 20kHz.
If live music is felt, please don't leave me out.
