Is flat frequency response desirable?
What is really desirable is flat frequency response AT THE LISTENING
POSITION - the "sweet spot."
The speakers need not be perfectly flat but should be reasonably so over the
full audio spectrum. High end speakers plus a good subwoofer is usually
needed to achieve this. Room acoustics are usually very unflat due to
resonances and reflections, but this can be improved by proper acoustic
conditioning and speaker placement.
Then the serious audiophile uses, or hires a tech to install and set up, a
GRAPHIC EQUALIZER - at least 10 band, preferably more - to minimize the
nonlinearities in the frequency response at the primary listening position.
I use a DOD 231Q 31- band dual (2 channel) graphic EQ. The settings for
both channels are the same as the speakers are matched and symmetrically
located.
Truly flat response input to ear, even if only within +/- a few db over the
entire audio spectrum, will absolutely amaze you!
