Frequency response + or - 1 dB ??

You are right, @viridian 

I meant to say that with better manufacturing this is a thing of the past.

But I think different approaches were taken. One, to match drovers, another, to change the crossover for each speaker

Can a single driver of any material provide flat frequency response within its operating range?

@ptss

A number of them can, some more expensive than others, it's just a matter of picking the right operating range for them. :)

I agree with the others that it really isnt that important. I think the main point is and should be what does a manufacturer have to do to get his speaker to measure flat. In my experience you lose more designing a speaker (with this as its main goal) that measures flat than you gain when this goal is achieved. But I was never a Dunlavy fan so what the hell do I know.
