The whole speaker is designed around this corner loading and to measure it in an anechoic environment will give results that are completely irrepresentitive of the actual performance when the setup is done as intended by the designer. In order to get flat frequency response from them they must be corner loaded as the designers intended.
Actually the frequency response from them is far from flat, corner loaded or not.

Many speakers are designed for specific placement. This does not mean that the manufacturer has the right to claim a specification that is in total disregard of standard measurment practice. FWIW; you could corner load any speaker and come up with wildly enhanced readings. It would be very tempting to fudge the data that way but as far as I know there's only one speaker company that does.
