Keith,
in the specifications sheet of the Kiis, it’s stated the following: «Frequency response: 30Hz to 25kHz +/- 0.5dB».
Because higher sound frequencies are absorbed in air, I wonder how you can state an error of just 0.5 dB up to 25 kHz.
In normal atmospheric conditions, like in a room on earth, 25 kHz is absorbed by about 0.7 dB after 1 meter.

So I wonder how you can have a speaker with a flatter response than what’s possible in a room on earth.
This raises the question if the Kiis were measured on the moon, or even Mars? Or were the measurements done at CERN, maybe in a special gas room?
It would be highly entertaining if Kii could comment on which special circumstances they were under when these measurements were made.
