Flat frequency response


I am often surprised by the number of speakers with "gee-whiz bang" technology but can't even get speaker design 101 right. I can see the benefit of avoiding a lot of signal processing but preferences notwithstanding, flat frequency response seems like the logical place to start and then progress from there.

1) Why is it so hard to achieve?

2) Does it matter?

3) Is it reasonable to say when you skip the basics you are only progressing on a flawed foundation.

JBL engineers speak about flat frequency response in monitor speakers. They believe it should have uniform on and off axis frequency response both horizontally and vertically at all angles. 😎 See article below:

Flat frequency response

''There is another aspect of the spatial domain that is important. This is that the frequency response should be the same in all the directions in which sound is radiated. That is the same as saying the directivity pattern is independent of frequency. If this is not the case, the speaker may fail to excite reverberation that can be identified as such by the ear because it will be coloured.''
