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.

I agree with you.  I'm often surprised when I get to the measurements part of a Stereophile speaker review, and read about strange anomalies of the design, and then see a not-so-good waterfall plot from a very expensive speaker.

It might be because a speaker that measures ruler flat sounds like crap in an actual room.  Just a semi-educated guess.

but can’t even get speaker design 101 right.

 

Can you please point us to speakers you have designed in the past? A write-up or measurements of them? Where did you take Speaker Design 101?  Is there a particular author /  engineer whose course or book on speaker design you are referring to?

That’s the sort of background I would expect from a post that claims speakers are not designed correctly.

My guess, based on your questions is that you have none of that background, but are interested audiophile who is trying to understand the meaning of frequency response measurements. 

Best,
