Frequency response + or - 1 dB ??

I realize the simplest crossover better the sound.  Frequency response starts with flat responce drivers.  Next the cabinet is, especially the front baffle, designed to help naturally flatten drivers.  Finally proper crossover points and the least amount of notch filters possible.  The more crossover to flatten response can certainly make a flat responce sound horrible. Keep it simple, simple, simple.  

As I remember, John Otvos' Waveform speakers actually achieved this via NRC measurements.

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
