Frequency response + or - 1 dB ??


The technical material world is full of incredible precision - watches as a mundane example. Why can’t the best loudspeaker manufacturers create a loudspeaker with + or -  1/2 dB frequency response within the rather limited 20 to say 30,000 cps range?

I do want to point out that components are a lot better than they were in the 1980s.


Drivers are, by and large, more consistent, and cheap 1% film caps are readily available.


It's a lot less important to match drivers and caps than it was then, and it is a lot less effort. This is a good thing especially when you consider having replacement parts on hand. Imagine if a driver in a hard to match speaker goes out. You'd have to send both speakers back to the factory to have them matched and possibly have the crossover updated. What a giant PITA!

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. :)
